6 BLL BERINGS INTROUTION EXTR SMLL SERIES Extra small bearings are available in the 30 Metric Series, the 33 an S Inch Series an the F Flange Series. These bearings can sustain raial, thrust an combine loas proportionate to the capacities of the small shafts for which they are esigne. They are appropriate for use in fractional horsepower motors, precision instruments, omestic appliances, film projectors an similar evices. The F flange series has external shoulers with the bearing for mounting in through-bore housings. This series is use where compactness is essential or where it is not feasible to machine housing shoulers. ll series in the extra small family inclue shiele versions. The 30 Metric Series is also available with felt seals, Mechani-Seals an rubber seals, while the 33 an S Inch Series is available with rubber seals. Some sizes in the Extra Small Series are manufacture from stainless steel. Extra small 33 an S series business machine bearings Stanar an special extra small bearings are available an often use in business machine applications. They inclue clamp-type collar bearings for slip-fit mounting on shafts, bearings with Wireloc in the outer ring, an rubber cushione O series with special house units. EXTR LIGHT 9300 N 9100 SERIES Bearings in the Extra Light 9300 an 9100 Series are ieally suite for applications where housing iameters are restricte an it is esirable to maintain relatively large shaft iameters. Both series are mae in the onra or non-filling slot construction with the 9300 Series having a somewhat thinner section. The 9100 Series is generally available with shiels, rubber seals an snap ring combinations. The 9300 Series is selectively available with two rubber seals. Machine tools, textile machinery an jet engine gear boxes are some of the en proucts in which these series have foun wie use. LIGHT 200 SERIES Bearings in the 200 Series have a greater section height than the Extra Light 9300 an 9100 Series bearings an feature a close imensional balance between bore, outsie iameter an with. These characteristics make them well-suite for a broa range of applications involving light to meium loas combine with relatively high spees. Their versatility has mae them a popular esign choice of esigners an has resulte in many variations in the series. They are available in either the onra or maximum capacity type an with shiels, rubber seals, Mechani-Seals, felt seals or a combination of shiel an seal. Snap ring combinations are also inclue. Wie-type 200 Series rubber seal (W200PP) an Mechani-Seal (W200KLL) bearings are mae with stanar bores an outsie iameters, but in withs equal to the corresponing sizes of ouble-row bearings. This series offers a larger support area for shaft an housing contact an extra space for lubricant. MEIUM 300 SERIES The 300 Series raial ball bearings are similar in construction to the 200 Series, but have consierably heavier cross sections throughout. They provie greater raial an thrust capacity an are able to withstan heavier shock loas. Because of their rugge construction, these bearings are particularly suite for heavy-uty applications like those foun in large electric motors, wooworking machinery an gear boxes. This series inclues both onra an maximum capacity esigns as well as shiele, seale an snap ring variations. In the 300 Series wie-type, rubber seal (W300PP) an Mechani-Seal (W300KLL) bearings are mae with stanar bores an outsie iameters, but in with equal to the corresponing sizes of ouble-row bearings.

TRI-PLY SEL ISK HRROW BERINGS Bearings with Tri-Ply Seals are esigne for service involving severe contamination, such as isk harrows, isk tillers an other see preparation equipment an certain conveyor applications. Tri-Ply seale units come in two esigns one consisting of three Timken rubber seals separate by steel spacers an retaine by steel caps in the outer ring an the other, a highly effective one-piece, mole seal esign. Both esigns have an exterior shrou cap to protect the seals an reinforce the exceptional sealing action of the complete unit. patente notche seal groove esign, provie on selecte sizes, is one of the most positive seal retention methos ever evelope. HEX BORE BERINGS These bearings are esigne for either outer or inner ring rotation in low spee, moerately loae applications such as farm machinery an conveyors. Their chief avantage is ease of mounting. Except for axial positioning by ajacent parts, no collars, setscrews or other external parts are require to lock the inner ring to the hex shaft. R-SEL ISK HRROW BERINGS R-Seal bearings are esigne for a wie variety of farm machinery applications where single-lip positive contact seals are require. Each sealing element has a Timken Fafnir rubber seal that effectively seals the bearing with a heavy flare on the cylinrically groun O.. (inner ring). steel back-up plate supports the seal rubber an prevents the seal lip from inverting. n outsie metal shrou cap gives maximum abrasion protection to the rubber element an completes the assembly that is rolle into the outer ring seal groove for positive retention. R-Seal raial ball bearings are use in positions in planting, cultivating an harvesting machinery. They are available in various configurations incluing roun bores in metric an inch imensions an cylinrical an spherical outsie iameters. NGULR ONTT SINGLE-ROW 7000 PROUT FMILY Timken offers a 7200WN Light, 7300WN Meium an 7400WN Heavy Series singlerow, angular contact bearings, which are esigne for combination loaing with high-thrust capacity in one irection. The 7000WN bearings are manufacture with better than BE 1 inner ring bore tolerances an BE 3 running accuracy. These bearings, when mounte in a uplex arrangement, provie axial an/or raial rigiity in applications where control of shaft isplacement is essential. These bearings are available with various cage esigns as efine in the imension tables. The external imensions of all 7000WN bearings interchange with corresponing sizes in the 200, 300 an 400 single-row raial series. NGULR ONTT OUBLE-ROW ouble-row ngular ontact Bearings are available in the Light 5200 an Meium 5300 Series. These bearings have the same bores an outsie iameters as the corresponing sizes in the 200 an 300 Series, single-row, raial type. hief avantages of the ouble-row type are rigiity, compactness an high capacity. The two rows of balls provie for bearings large raial capacity combine with moerate thrust capacity in either irection. ouble-row bearings are available in both the onra (K) construction with uninterrupte race shoulers an the maximum capacity type. The latter has a filling slot in the shouler of both rings an a maximum ball complement. Sizes with the W suffix have the filling slot on one sie only.

41 Raial an ngular ontact Ball Bearings 7000WN Prouct family Introuction The high performance 7000WN ngular ontact Prouct Family is specifically esigne to support heavy thrust loas at lower operating temperatures at high spees. Inclue in the angular contact series are the following esign features: Refine bore iameter Better than BE 1 bore tolerance iameter tolerances Increase thrust capacity High operating contact angle Extene loa capacity Improve ball section ratio Lower operating Low shouler inner an outer temperatures rings improve oil flow feature of this series is the refine bore iameter tolerance. The closer bore tolerance in the WN prouct family reuces the broa range of interference an thus prevents the evelopment of unesirable high preloa in mounte uplex pairs. s a result, longer bearing life is achieve an high operating temperatures are avoie. This prouct family can support heavy thrust loas by combining high shoulers on the thrust sie of both rings with a high operating angle. In aition, uniformity of loa per ball uner combine loas is more favorable with a high contact angle an results in longer bearing life. Maximum clearance between the one-piece brass or bronze cage an the lan iameters of both rings is achieve in the WN construction. Utilizing low shouler iameters on the non-thrust sies of inner an outer rings promotes efficient oil passage through the bearing resulting in lower operating temperatures an longer bearing life. The 7000WN Prouct Family is ivie into several esigns. Sizes WN an WN have a 40 egree contact angle an a one-piece, ball-pilote, presse brass cage. Sizes WN an WN have a 40 egree contact angle an a one-piece, outer ring-pilote, high-strength machine bronze cage. The 7412WN an 7415WN both have a 40 egree contact angle an a one-piece conical, high-strength machine bronze cage. The 7000WN Prouct Family is available as single bearings an uplex sets. single with the suffix SU is flush groun on both faces for universal mounting. Such bearings can be use as singles or uplex mounte back-to-back (B), face-to-face (F) or tanem (T), epening on the functional requirements of the esign. The mounting of uplex SU bearings will result in a preloa range of minimum internal clearance to a soli preloa. Bearings without the SU esignation are not flush groun an are intene to be use as singles. These bearings are use to support thrust from one irection an are often accompanie by a preloa spring. Bearings with the suffix U are flush groun on both faces for universal mounting. uplex pair of U bearings can be mounte (B, F, or T), epening on the functional requirements of the esign. These bearings, after mounting, will result in a range of positive light preloa. MOUNTING RRNGEMENTS pplications These esign features are avantageous in applications such as oil refining pump systems where higher prouctivity an longer system life is important. Other applications where these features are equally suite are eep well pump motors, vertical an horizontal pumps, worm gear an right angle rives, spinles, live centers an gearboxes. For applications requiring a high egree of axial an raial rigiity, these bearings are suggeste in preloae uplex mountings. Mounting lthough each 7000WN Prouct Family bearing is a self-containe unit, the construction is such that they are frequently mounte as two bearings oppose, so that thrust can be carrie in either irection. Unlike the raial type, the angular contact bearing, when mounte alone, requires ajustment an must be installe with care. s the bearing is relatively loose axially before mounting, it is important that the esign incorporate some means to move the outer ring axially into its correct position relative to the inner ring. This ajustment shoul be mae when the bearing is mounte. common metho is to place a preloa spring or shims at one bearing location. The correct ajustment of the single bearing is obtaine when the initial axial looseness of the assembly is remove. This eliminates the possibility of premature bearing amage ue to excessive preloaing or looseness through improper ajustment. Bearings esignate SU are groun on both surfaces to permit universal mounting. These uplex sets are ieally suite for applications which involve a combination of raial loas from either irection. SU bearings are flush groun so that uner a specific axial gage loa the inner ring will protrue beyon the face of the outer ring. This esign results in an internal axial clearance within the bearing pair that helps to minimize buil-up of excessive preloa within the bearings when mounte on a shaft with maximum interference. To assure correct mounting of bearings in the 7000WN Prouct Family, the wor THRUST is marke on the thrust face of both the inner an outer rings. This face shoul abut against the housing shouler or the en cover, epening on the require irection of "thrust". orering information SU Suffix: ll bearings are package singly.

The latitue of these classes allows for a significant range of variability in prouct performance among bearing manufacturers. haracteristics such as raceway curvature an uniformity; the balls conformance to sphericity; race an ball surface finish; waviness of contact areas; preloa offset tolerance; cleanliness; calibration of envelope imensions; matching of bearings within a set; cage esign an material; lubricant; raial play; contact angle an precision of ball complement are not efine by BE/ISO. ll have a irect impact on the service life an performance of a bearing. The lack of a comprehensive stanar allows inferior bearings to be markete as BE 7 or 9 (ISO P4 or P2) without the ability to prouce superior performance. ll Timken MM, MMV, an MMX precision grae comply with strict controls over these non-specifie parameters, to provie premium performance. OPTIMIZE GRES OF PREISION MM, MMV Super Precision, Super High Precision (BE 7/9, ISO P4/P2) Super precision bearings manufacture to the MM(V) tolerance class operate with running accuracy an performance levels meeting BE 9 (ISO P2) yet maintain non-critical features at BE 7 (ISO P4) level for cost-effectiveness. Bore an O.. surfaces are coe in micron units for the convenience of the iscriminating machine tool builer striving for optimum fitting of crucial spinle components. MMX Ultraprecision (BE 9, ISO P2) Super precision bearings with closer tolerances an running accuracies than BE 7 (ISO P4) bearings are mae to BE 9 (ISO P2) tolerances. Bearings prouce to these tolerances are generally use on ultra-high-spee grining spinles esigne for tight imensional tolerances an super-fine surface finishes. ontact your Timken representative for availability of prouct range. bearing types ngular-ontact Bearings 2MM-WI types with 15 egree initial contact angle are esigne to meet the nees of machine builers for precision bearings which will operate at as low a temperature as possible for a wie range of spees an operating loas. In orer for machines to prouce more accurate work at a higher prouction rate, the bearings must provie a high egree of rigiity in both axial an raial irections while operating at minimum temperatures. For example, precision machining or cutting tools impose heavier loas on bearings than those encountere in precision grining. In the former, spees are slower an loas heavier than the latter, where spees are high an loas light. The 2MM-WI Type gives the machine builer the flexibility require to meet such variations in applications. 54 TIMKEN PROUTS TLOG

57 Super Precision 3MM-WI manufacture with 25 egree contact angle, are for use on applications where the loaing on the bearings is preominately thrust an a high egree of axial rigiity is a efinite requirement. Typical applications for these are large vertical rotary surface griners, horizontal an vertical isc griners, an thrust bearing applications for heavy-uty lathes where the bearings must irectly carry extremely high tail stock or chucking pressure. 2MM-WI & 3MM-WI Types 2MM-WO with 15 egree initial contact angle are esigne for extremely highspee applications where centrifugal force of the balls is the principal loa on the bearing. Unlike the MM-WI Type, which has a low shouler outer ring, the 2MM-WO Type has full shoulers on both sies of the outer race an a low shouler on one sie of the inner ring. This esign permits assembly with a maximum complement of balls an a one-piece cage which pilots against the precision-groun lans of the outer ring. Generally this bearing series is supplie with a separable inner ring an ball retaining cage along with special race geometry for extremely high-spee operation. 2MMV an 3MMV-HX are imensionally interchangeable with equivalent 9100, 99100, 9300 an ISO Series-10 an 19 bearings. These esigns enable spinle heas to remove more material in less time while maintaining superior machining tolerances. This is achieve through a proven combination of unique ball complements with precision engineering raceway geometries. 2MMV an 3MMV-HX VV possess all of the high-spee avantages of the HX but with true high spee seals. These bearing seals protect lubricant from outsie contaminants while ensuring internal lubricant retention, extening service life significantly. 2MMV an 3MMV 99100WN are available with 15 egree or 25 egree contact angle variations an have been evelope to operate uner the emaning requirements of high-spee machine tools. They incorporate esign features which permit operation at higher spees than stanar angular contact ball bearings. The bore, outsie iameter an with are the same as the MM9100 Series. Ball Screw Support Bearings To meet the emans of the servo-controlle machinery fiel, the Timken Fafnir ball screw support bearings are specially esigne with steep contact angles an offer high levels of stiffness for ball screw application requirements. Timken s most recent prouct offering in this area is a series of ouble-row, seale, flange (or cartrige) units that use an integral ouble-row outer ring to help simplify installation proceures.

58 BLL BERINGS Introuction Workhea an tool spinles are the most important components of machine tools. onsequently, to reach the requirements for spinle spee, work accuracy an finish, selection of the proper size an type of ball bearings to support these spinles is a critical esign problem. Of all the anti-friction bearing types, super precision ball bearings have prove to be the best value for the wie variety of bearing applications covering broa ranges of operating loas, spees an lubrication conitions. uplexe, preloae, angular contact bearings with one-piece composition retainers, have excellent capacity an provie maximum spinle rigiity. These bearings are wiely use in achieving faster spees, greater accuracy, smoother finishes an higher prouction rates. Many consierations are involve in the choice of bearings for precision applications. mong those which influence the performance of machine tool spinles are the internal fit-up an geometry of the bearings, the mounting arrangement, the shaft an housing mounting fits, the balance an alignment of the rotating parts, an last, but equally important, the lubrication. While many of these factors are significant in slow-spee applications, all of them must be consiere for high-spee spinles. To minimize eflection uner loa, shafts for machine tool spinles are esigne to have a minimum unsupporte length an maximum cross-section. For the same reason, spinle housings are esigne heavy enough to carry the work loa. Their cross-sections are mae as uniform as possible to reuce stress concentration uring uneven eflection of the frame ue to thermal changes. In aition, heavy, well-proportione housings can function as sinks to conuct heat away from ball bearings. Selective ssembly Uner certain conitions it may be esirable to control fits more accurately without the ae expense of using closer tolerance bearings an assembly parts. This can be accomplishe by selective assembly of the bearings, shafts, an housings, after they have been size an sorte accoring to bores an outsie iameters. Timken provies bore an O.. micron coing as stanar practice for super precision angular contact raial ball bearings. This improve fit-up at assembly provies a higher egree of precision from the spinle. Successful pplications etaile assembly rawings on the following pages are representative of successful applications of Timken Fafnir super precision bearings on such equipment; high-cycle wheel heas; high-spee internal grining spinles; super precision work heas; an high-spee router spinles. It is hope that these arrangements will stimulate questions regaring your particular application problems which will promptly be aresse by your Timken representative. Special Requirements High-spee grease-lubricate spinles an heavy precision workheas requiring unusual rigiity an running accuracy are a few of the many special problems involving super precision bearings. These an many other applications generally require esign features that can be reviewe by your Timken representative. 56 TIMKEN PROUTS TLOG

59 Super Precision pplications High-Spee Internal Grining Spinle esigne for internal precision grining, this spinle incorporates 2MM9106WO-R super precision bearings, preloae by a nest of coile helical springs mounte in a cartrige. Thrust loa exerte by the springs assures intimate contact of the balls with the bearing raceways uner all operating conitions. The seale construction provies highly effective protection against intrusion of coolant an foreign matter. Grease, packe in each bearing prior to assembly, is seale-in for life. Operating spee of this spinle is RPM. Ultra Precision Surface Grining Spinle 2MMX9122WI-UM super precision bearings, prouce to BE9 tolerances, are employe in this horizontal surface grining spinle for maximum rigiity an accuracy. back-to-back pair of 2MM312WI-R-UL super precision bearings is use at the floating location. This spinle grins surfaces that are accurate within inch, flat an parallel, are square within inch, an to a surface finish of 5 rms, or better. The spinle, riven by a 30 hp motor, operates at 900 RPM. Bearings are packe with grease prior to assembly. Precision Surface Grining Spinle This motorize surface grining spinle, operating at 3600 RPM, uses 2MM9107WI-UM uplex super precision preloae bearings at both locations, mounte back-to-back, with one pair floating. Labyrinth slinger-type sealing prevents entry of contaminants an seals in the lubrication. Bearings are grease lubricate for life. Heavy-uty Precision Boring Spinle Super precision, uplexe, preloae bearings mounte backto-back are use at each location in this boring spinle to assure smooth performance an a high egree of raial an axial rigiity. Operating spees vary between 200 an 3000 RPM. Equal-length spacers between the bearings at the work en increase spinle rigiity. When the bearings are properly positione on the shaft an the respective rings securely clampe, the preloa is reprouce an no subsequent ajustment is require. Just prior to assembly, each bearing is packe with grease for life. Six-Spinle utomatic Screw Machine This bearing arrangement meets the eman for a high-spee, heavy-uty, multiple-spinle screw machine to operate with constant accuracy at maximum prouction. Because of the hollow shaft construction an the short istance between bearings, extralight series uplex pairs are use at each location. This affors a high egree of raial rigiity an as stiffness to the shaft. By mounting a uplex pair of flange (3MMF) bearings with a 2MM super precision bearing, back-to-back, uner a preetermine preloa at the front en, accuracy an rigiity of the spinle are assure an permit a straight housing bore. The rear pair of back-to-back bearings is allowe to float in the housing, making an outer-ring spacer unnecessary. Lubrication is by pressure-fee oil circulation. TIMKEN PROUTS TLOG 57

60 BLL BERINGS High-Spee Precision Boring Hea This high-spee boring hea operates at 2500 to 3000 RPM, employing angular-contact, super precision bearings. The front bearings are of ifferent sizes. The outer ring of the larger bearing abuts an is clampe against the housing shouler. The inboar bearing is permitte to move axially in its housing uner spring loa. t the rear location two bearings, of the same size an spring loae, are allowe to float in the housing as temperature ifferentials occur in the operation spinle. With this hea, interference shafts may be permitte without affecting bearing preloa. Excessive heat generation is prevente, resulting in low operating temperatures. Bearings are grease lubricate. Ultra Precision Grining Workhea This workhea must maintain straightness an rounness accuracy within ten millionths ( ) of an inch. To meet such rigi requirements for extremely close imensional control, ultra precision ball bearings an a shaft of extra stiffness are use. The bearings for such applications are manufacture to tolerances closer than those for BE 9 (ISO P2) specifications. Equally important is the high egree of workmanship an accuracy with which the shaft, housing an component parts of the workhea must be mae. Upper section shows a four-bearing arrangement for heavy work. Lower half shows a two-bearing mounting for lighter work. In either case, the bearings are packe with grease, prior to mounting. Precision Toolroom Surface Griner Spinle Timken Fafnir uplexe, super precision, preloae bearings use in this spinle provie the high egree of rigiity in both irections necessary to meet requirements for moern surface grining an to assure efficient performance at a low operating temperature. The housing is bore straight-through to assure true alignment the housing shoulers are eliminate. The precision groun outer sleeve is owele to the housing to provie the means for stabilizing the spinle axially at the work en bearing location. The rear pair of bearings floats to compensate for thermal changes. Bearings are grease lubricate for life just prior to assembly. Single Bar Machine This spinle is supporte by two pairs of 2MM9124WI-UM super precison bearings, mounte back-to-back in tanem pairs. Operating spees vary from 78 to 1500 RPM. pair of 2MM9122WI- UM bearings mounte in tanem carries a poun thrust loa uring the unchucking operation. The bearings are grease packe for life prior to assembly. 100,000 RPM High-ycle Wheelhea Super precision 2MMX9101WO-R bearings prouce to BE 9 (ISO P2) RPM tolerances are spring-loae in this wheelhea which operates at 100,000 RPM.
