Spherical Roller Bearings

1 Spherical Roller earings MOUNTING PROEDURES Depending on the size of the bearing and the application, there are different methods for mounting roller bearings. In all methods, certain basic rules must be followed. EANINESS hoose a clean environment, free from dust and moisture. The installer should make every effort to ensure cleanliness by use of protective screens and clean cloths. PAN THE WORK Know in advance your plans and have the necessary tools at hand. This reduces the amount of time for the job and decreases the chance for dirt to get into the bearing. INSPETION AND PREPARATION All component parts of the machine should be on hand and thoroughly cleaned before proceeding. Housings should be cleaned, including blowing out the oil holes. Do not use air hose on bearings. If blind holes are used, insert a magnetic rod to remove metal chips that might be lodged there during fabrication. Shaft shoulders and spacer rings contacting the bearing should be square with the shaft axis. The shaft fillet must be small enough to clear the radius of the bearing. On original installations, all component parts should be checked against the detail specification prints for dimensional accuracy. Shaft and housing should be carefully checked for size and form (roundness, etc.). SHAFT AND HOUSING FINISH Shaft surfaces on which the bearing will be mounted must be clean and free from nicks and burrs. For applications with stationary housing and rotating shaft, it is suggested that the bearing seat on the shaft be ground to.6 μm (65 μin.) Ra maximum. If it is impractical to use a ground finish, a machined finish of 3.2 μm (25 μin.) Ra is acceptable in many cases, but the amount of interference fit should be slightly increased. Housing bores should be finished to 3.2 μm (25 μin) Ra maximum. MOUNTING YINDRIA ORE EARINGS Heat Expansion Method Most applications require a tight interference fit on the shaft. Mounting is simplified by heating the bearing to expand it sufficiently to slide easily onto the shaft. Two methods of heating are commonly used: - Tank of heated oil. - Induction heating. The first is accomplished by heating the bearing in a tank of oil that has a high flash point. The oil temperature should not be allowed to excee2 (250 F). A temperature of 93 (200 F) is sufficient for most applications. The bearing should be heated for 20 or 30 minutes, or until it is expanded sufficiently to slide onto the shaft easily. The induction heating method is used for mounting small bearings in production line assembly. Induction heating is rapid. are must be taken to prevent bearing temperature from exceeding 93 (200 F). Trial runs with the unit and bearing are usually necessary to obtain proper timing. Thermal crayons melted at predetermined temperatures can be used to check the bearing temperature. While the bearing is hot, it should be positioned squarely against the shoulder. ockwashers and ocknuts or clamping plates are then installed to hold the bearing against the shoulder of the shaft. As the bearing cools, the ocknut or clamping plate should be tightened. In cases of outer ring rotation, where the outer ring is a tight fit in the housing, the housing member can be expanded by heating. The oil bath is shown in Fig. 26. The bearing should not be in direct contact with the heat source. The usual arrangement is to have a screen several inches from the bottom of the tank. Small support blocks separate the bearing from the screen. It is important to keep the bearing away from any localized high-heat source that may raise its temperature excessively, resulting in race hardness reduction. A Note: Do not remove the bearing from its wrapping until you are ready to mount it. EARING EARING HED FROM OTTOM Y SREEN OI EARING SUPPORT OK FAME URNER Fig. 26. Heat Expansion Method. Flame-type burners are commonly used. An automatic device for temperature control is desirable. If safety regulations prevent the use of an open heated oil bath, a mixture of 5 percent soluble-oil water may be used. This mixture may be heated to a maximum of 93 (200 F) without being flammable.

2 SPHERIA ROER EARINGS A MOUNTING PROEDURES - continued MOUNTING YINDRIA ORE EARINGS - continued Arbor Press Method The alternate method of mounting, generally used only on smaller sizes, is to press the bearing onto the shaft or into the housing. This can be done by using an arbor press and a mounting tube as shown in Fig. 27. The tube can be made from soft steel with an inside diameter slightly larger than the shaft. The O.D. of the tube should not exceed the maximum shoulder height given in the table of dimensions. The tube should be faced square at both ends. It should be thoroughly clean inside and out and long enough to clear the end of the shaft after the bearing is mounted. SHAFT MOUNTING TAPERED ORE SPHERIA ROER EARINGS Use a feeler gage with the thinnest blade of.005 in. Place the bearing in an upright position with the inner and outer ring faces parallel. Place thumbs on the inner ring bore and oscillate the inner ring two or three elements. Position the individual roller assemblies so that a roller is at the top of the inner ring on both sides of the bearing. With the roller in the correct position, insert a thin blade of the feeler gage between the roller and the outer ring. Move it carefully along the top roller between the roller and outer ring raceway. Repeat this procedure using thicker feeler gage blades until one is found that will not go through. The blade thickness that preceded the no-go blade is a measure of RI before installation. Start the mounting procedure by lubricating the tapered shaft with a light coat of machine oil. Fig. 27. Arbor press method. If the outer ring is being pressed into housing, the O.D. of the mounting tube should be slightly smaller than the housing bore. The I.D. should not be less than the suggested housing backing diameter in the table of dimensions. oat the shaft with a light machine oil to reduce the force needed for a press fit. arefully place the bearing on the shaft, making sure it is square with the shaft axis. Apply steady pressure from the arbor ram to drive the bearing firmly against the shoulder. Never attempt a press fit on a shaft by applying pressure to the outer ring or a press fit in a housing by applying pressure to the inner ring. Fig. 28. Slide the bearing onto the shaft as far as it will go by hand. As the ocknut is tightened, the interference fit builds up, resulting in expansion of the inner ring. Periodically measure to keep track of the reduction in RI. ontinue the procedure until the proper amount of reduction is obtained. Do not exceed suggested amount of reduction. As a final check, make sure the remaining RI equals or exceeds the minimum mounted clearance shown in the table to the right. 04 SPHERIA ROER EARING ATAOG

9 Spherical Roller earing Pillow locks INTRODUTION Timken s capabilities in the engineering and manufacture of heavy-duty pillow blocks provide important user benefits. In addition, Timken s worldwide sales organization is staffed with experienced bearing engineers who are available for consultation on any pillow block or bearing application. Expert engineering DESIGN AND ONSTRUTION Timken supplies pillow blocks equipped with either tapered bore bearings plus adapters for mounting on straight shafts or cylindrical bore bearings for assembly on shouldered shafts. Timken spherical roller bearing pillow blocks are made of split construction for convenient assembly and disassembly. These units include pry tool slots and the exclusive Pry-ug fulcrum that simplify bearing inspection, service, and replacement. aps can be removed easily and quickly without damage to the bearing or housing. Precision fit is ensured by the Timken system of doweling caps and bases together at an early stage of manufacturing, so that they remain a single unit during machining. They are not interchangeable as separate parts and become precisely mated components. assistance is available for applications involving shaft sizes 40 inches and larger such as OF trunnions, bridge blocks and ball mills. If your design calls for shaft sizes or loads not listed in this catalog, contact your Timken representative for information about availability of special units. Timken manufactures pillow blocks in two styles: SAF and SDAF. The larger SDAF block is suggested for extreme duty applications. aps and bases are made from high-grade, stress-relieved cast iron as standard. They also are available in cast steel. All Timken pillow blocks are designed for four-bolt mounting. ertain smaller sizes are normally furnished for two-bolt mounting. These assemblies are indicated in the tables and can be ordered with optional four-bolt base. Four cap bolts are used in most Timken pillow blocks in order to equalize the pressure between cap and base, preventing loss of lubricant. The illustration below shows all parts of a pillow block assembly that are described throughout this section. olt & Washer ER Seal Ring Spherical Roller earing Fig. 30.

10 SPHERIA ROER EARINGS MOUNTING ADAPTER VS. STRAIGHT ORE Usually a spherical roller bearing pillow block assembly is mounted on a straight shaft using a tapered bore bearing and adapter assembly. Standard commercial shafting can be used without additional machining. (Suggested shaft diameters are shown on page 20.) Adapter mount also permits maximum flexibility in the axial positioning of the bearing on the shaft and will accommodate light locational thrust loads. Timken pillow blocks for tapered bore and adapter mounted bearings are available in Series 225, 226, 230, 23K and 232K. Adapter mounted spherical roller bearings require the correct removal of diametral clearance from the bearing to prevent relative rotation between inner race and sleeve or shaft. Failure to employ proper mounting procedures can cause heating and reduced bearing performance. For proper shaft mounting of adapter type spherical roller bearings, see page 04 of the spherical roller bearing section. When application conditions produce heavy thrust loads, or a need exists for exact axial location or a positive shaft interference fit, a direct straight bore mounting may be the best option. This requires a shouldered shaft, machined for proper fit, and a straight bore bearing. Timken pillow block assemblies for straight bore applications are available in Series 222, 223, 23 and 232. Suggested fits for shafts in cylindrical bore spherical roller bearings are shown in the engineering section. For applications involving heavy shock, vibration, unbalanced rotating loads or other abnormal conditions, consult your Timken representative. FIXED AND FOAT PIOW OKS Any style of Timken pillow blocks can be easily installed either at the float or fixed position on the shaft. For the fixed position, a stabilizing ring is added between the bearing outer face ring and the housing shoulder to positively locate the shaft and prevent axial movement. Some applications require centering of the bearing in its housing. To accomplish this, two special width stabilizing rings can be ordered. In the float position, the ring is not used, allowing the bearing to move axially (a maximum of 3 / 8 in.) to compensate for thermal expansion or contraction of the shaft. Pillow blocks ordered by the numbers in the dimension tables are fixed units. To order float units, specify by adding suffix Float or F to the pillow block number. OSED END INSTAATIONS In some applications, the shaft end is designed to terminate inside the pillow block. For this design, positive fitting end-closure inserts are available to seal out contaminants and retain lubricant. Timken heavy-duty end plugs include O-rings for positive sealing. Designers and installers need to make sure the shaft end does not contact the closure. A minimum of / 8 in. clearance at maximum thermal expansion is suggested between the end of the shaft and the closure. Dimension Y in the tables defines the maximum permissible length of the shaft from the centerline of the pillow block housing. If end closure is desired, specify by adding (one end closed) to the pillow block assembly number. URIATION Timken pillow block housings have been designed for grease and oil bath lubrication. They also can be modified easily to accommodate circulating oil or oil/air mist systems. Grease fittings or sight gages are available upon request. A lubrication groove and oil holes are provided in the bearing outer ring. This feature, designated by adding suffix W33 to the bearing number, should be specified whenever re-ordering bearings for pillow blocks. In most cases, the fresh lubricant is fed directly to the center of the bearing between the rows of rollers and distributed to the rest of the bearing. This ensures the used lubricant is purged from the bearing. SEAS Precision triple ring labyrinth seals are supplied with all Timken pillow blocks to exclude foreign matter and retain lubricants. The pillow block base includes extra large oil return holes at the bottom of the seal grooves to prevent leakage past the seals. For extremely contaminated or abrasive environments, Timken has developed the exclusive DUSTA seal. This patented seal offers protection against concentrations of dust or abrasive material that a labyrinth seal cannot keep out. See page 23 for further information on DUSTA. OAD RATINGS AND IFE oad ratings for the spherical roller bearings that are used in pillow blocks are found in the dimension tables on pages 80 through 96. ife calculation formulas are found in the engineering section. In addition to individual bearing selection, the ability of the pillow block to carry the operating load should be considered. It should be noted that the load rating figures supplied in this catalog are applicable only when the load direction is generally toward the base of the pillow block. If the pillow block must be mounted so the load can be applied in any other direction, consult your Timken representative. 2 SPHERIA ROER EARING ATAOG

22 SPHERIA ROER EARINGS INH SINE AR GAGES Tapered-bore, anti-friction bearings are mounted either on adapter sleeves or on tapered shaft seats. In cases where tapered bore bearings are mounted directly on the shaft, the shaft must conform to the tapered bore of the bearing to assure proper fit. If a proper fit is not achieved, the results could be:. Turning of the bearing inner race on the shaft. 2. Uneven loading of the bearing. 3. Severe inner race hoop stress. 4. Insufficient support (back-up) of the inner race on the shaft. All of these conditions could lead to premature bearing damage. Therefore, the manufacture, maintenance and measurement of accurate shaft tapers is important. There are two accepted ways of measuring tapered shafts: ring gages and sine bar gages. Precision measurement of tapered shafts is difficult with ring gages and may be impossible in the case of large shafts where gages are large, cumbersome and heavy. Sine bar gages provide an accurate and easy method of measurement. ightweight and easy to handle and learn, sine bar gages achieve precise gaging of the shaft size and taper. Fig. 32.

23 Spherical Roller earing Pillow locks INH HYDRAUI NUTS INTRODUTION Designed to install and remove tapered bore bearings with minimal effort. Allow better control of the bearing internal clearance reduction without damaging the bearing or other components. Substantially reduces downtime during installation or removal of tapered bore bearings. DESRIPTION onsist of a female threaded ring and a male ring with two O-ring seals. All hydraulic nuts are supplied with: - Quick connection fittings (male ¼ in..s.p. and female 3 / 8 in. N.P.T.). - Two pipe plugs ¼ in..s.p. - One set of spare O-rings. INSTRUTIONS When the hydraulic nut is used, the piston must be in the innermost position. For this operation, please ensure the valve of the hydraulic hose is disconnected from the nut so the nut is not under pressure. To contract the piston inside the female threaded ring, insert a rod or bar in one of the four drilled holes located on the outside diameter of the female threaded ring. Screw the hydraulic nut on the thread with the piston in contact with the surface, until the groove machined on the outside diameter of the piston near the outboard face is level with the face of the female threaded ring. One of the two threaded holes must be plugged with the ¼.S.P. pipe plug before the hydraulic nut is pressurized. The maximum pressure permissible in the hydraulic nut is 4000 psi (0 Kpa). The oil viscosity suggested is 400 SUS (300cSt) at operating temperature (SAE 90 oil). To avoid overextension of the piston, a second groove has been machined on the outside diameter of the piston inboard used to judge contraction. When this second groove is level with the face of the female threaded ring, the piston has reached its length of travel as shown in the illustration. If the second groove of the piston travels past the face of the female threaded ring, the hydraulic nut can be damaged. Should the oil start to leak from the piston area, it is certain that the O-ring seals are damaged or worn and need to be replaced. When the hydraulic nut is not in use, ensure that the threaded holes are plugged to prevent entry of contaminants in the piston cavity. To help prevent against corrosion during storage, apply a coat of light oil on the hydraulic nut surfaces. ontact your Timken representative to receive special warnings against reasonably unforeseen dangers. ORDERING OMPONENTS: To order spare components for the hydraulic nuts, order part numbers as listed below: - O-ring Seal Kits: Use the hydraulic nut part number plus the number 32. Example: HMV 40/32 - Pipe Plug ¼ in..s.p.: Use the hydraulic nut part number plus the number 647. Example: HMV 40/647 - Quick onnection Fittings (male ¼ in..s.p. and female 3 / 8 in.

38 SPHERIA ROER EARING METRI AESSORIES Accessories for your every need. To complement our line of Timken spherical roller bearings, we offer bearing sleeves and locking devices in a wide range of metric sizes. These accessories are manufactured to the same quality standards as our bearings, ensuring a secure fit to straight and stepped shafts. Available in sizes up to 900mm, bearing sleeves are available in two distinct designs: assembled adapter sleeves and withdrawal sleeves. ADAPTER SEEVES Timken adapter sleeves are used in conjunction with a nut and locking device to mount a tapered bore bearing onto a straight shaft using a pull-type fit. Smaller size assemblies (7 mm mm shaft) commonly use simple nuts, whereas larger assemblies (sizes >200 mm) may use HMV hydraulic nuts to assist in mounting. The chart below outlines our part number nomenclature, which is consistent with the world standards for adapter sleeves. Sleeve ocknut ocking Device H standard metric KM M OH hydraulic assist HM M KM M WITHDRAWA SEEVES Withdrawal sleeves feature a push-type mounting arrangement and a locking device (i.e., ocknut or ockplate) to secure a bearing to a shaft. This design is not as widely used as the adapter sleeve assembly and it does require the use of a specially designed dismounting nut. Timken s part number nomenclature for withdrawal sleeves also conforms to industry-accepted standards.
