These beas equie minimum space and povide maximum ated capacity. Vaious configuations including sepaable o oute combinations offe ample application flexibility. ings of high quality bea steel fo stength, toughness and duability. Micofinished aceways assue smooth opeations. Exclusive honed cown on olle pofile fo optimized aceway contact aea and high capacity. Stuctual design segmented etaine povides high stength, positive olle spacing and guidance. One-piece fomed steel etaine povides positive olle spacing and contolled olle guidance. Polymeic etaine of glass fibe einfoced nylon 6/6 povides full olle guidance, supeio lubication and educed noise. G-1

2 Segmented etaines igid stuctual design segmented steel etaine povides high stength, positive olle spacing and guidance. ll contact sufaces ae contoued to minimize the wiping action between etaine segments and olles, assu full olle lubication. Pecision space segments contact the olles above and below pitch esulting in low fiction loss and positive olle contol. Polymeic etaines Made of glass fibe einfoced nylon 6/6, molded polymeic etaines povide close contol of olle "dop," low noise, full olle guidance and supeio lubication, at a competitive pice. Extensive testing has established compatibility with a boad ange of standad lubicants and satisfactoy opeation at sustained tempeatues to 275 F. Fomed Steel etaines One-piece deep coined fomed steel etaine combines stength with positive olle spacing and olle guidance. The etaine guides the olles below the pitch line and povides contol of olle dop. Line contact of olles on guidance sufaces minimizes wiping action and pomotes hydodynamic lubication. olles Exclusively cowned honed olles povide optimized contact at the aceway. This assues efficient bea pefomance unde, povides contolled stess distibution unde all s within the design capacity and compensates fo shaft deflection. ings ings ae manufactued fom high quality bea steel to enhance fatigue esistance, stength, toughness and hadenability. eas and and olle assemblies fo omitted- applications ae M standad bounday plan fo boe, outside, and width standad toleances ae E-1.

5 Selection ylindical olle eas To select a bea, detemine the applied adial, any applied thust, the desied ating Life, and applicable ope conditions. The pocedue shown hee will aid in selecting a bea to meet an L₁₀ design life. The fomulas fo calculating life expectancy should be used to detemine the ating Life L₁₀ fo the bea selected. ylindical olle beas ae available in vaious seies with cylindical boes fo diect shaft mounting. eas in seveal seies may fulfill the L₁₀ life equiements. Speed limits, minimum shaft s, aangement equiements and space limitations may be detemining factos in final bea selection. ea Selection The selection pocedues and fomulas shown hee ae in ageement with The meican ea Manufactues ssociation Standads and NSI/M STD atings ae based on fatigue life. The ating Life L₁₀ o fatigue life at 90% eliability is the usual basis fo bea selection. ylindical olle beas ae essentially adial beas. Nevetheless those styles whee integal ibs ae in the pope location on and oute s will also suppot thust ing. In fact, most such styles do suppot incidental, axial locating s. Wheneve applied thust ing is known to exist, the guidelines given fo Thust Loads on p. G-6 must be caefully followed. Selection and life expectancy fomulas shown hee ae also valid fo and olle assemblies and fo oute and olle assemblies povided they ae un diectly on bea quality steel shafts o housings popely hadened and gound. To assue a satisfactoy bea application, fitting pactice, mounting, lubication, sealing,, housing stength, ope conditions and maintenance must be consideed. Step 1 Detemine an appopiate L₁₀ design life.

Step 3 alculate the equied and select a cylindical olle bea. P = F equied = P using fom Step 2. Select a cylindical olle bea of the desied type having a basic equal to o geate than the equied fom the appopiate seies. The life expectancy of othe sizes and seies of cylindical olle beas can be calculated. When thust is pesent, check the individual bea thust capacity and follow the equiements fo lubication unde thust conditions. Step 4 Detemine the pemissible speed limit of the bea though the following pocedue: Pemissible speed limits ae of pactical value only when consideed with othe factos of bea opeation. Not evey application functions satisfactoily at the listed speeds. Load, lubication, and tempeatue factos influence the pefomance. ea opeation at the listed speed limit demands excellent lubication, modeate, and easonable tempeatue envionment. Pemissible speed can be appoximated fom the limiting DN value, which is the poduct of the bea boe in millimetes and the speed in PM. The DN values shown below ae nominal. Fo highe pemissible speeds, consult Link-elt ea Division, exnod opoation.

Thust Loads The integal guiding ibs on standad cylindical olle bea and oute s will suppot limited thust s. In addition, special toleances and pocessing can be used to substantially incease axial capacity. In eithe case, excellent lubication (pefeably with an EP lubicant) and a stabilizing adial ae equied.

Whee application conditions exceed eithe of these limits, Link-elt ea Division should be consulted.

Fo most nomal applications, all factos will be taken as 1, and the ating Life used as the selection basis o life estimate. In addition, as long as standad catalog beas ae used, a₂ will be nomally set equal to one. The facto a₃ coves such things as lubication, misalignment, and tempeatue. Some conditions that could yield a₃ significantly diffeent than unity include speeds less than DN o geate than DN, tempeatues below 40 F ( 40 ) o above 275 F (135 ), o misalignment geate than adians..

Othes can be made available fo poduction equiements. dditional Featues: ylindical olle beas ae available with many combinations of standad featues. The nomenclatue page G-32 and the index pages G-3 and G-4 all descibe standad featues which esult in cylindical olle beas being extemely vesatile fo specific applications. Fo othe mounting aids such as dowel coin holes and snap s and gooves, consult Link-elt ea Division. Opeation: ylindical olle beas ae designed fo gease o oil lubication. Oil is most commonly used. Sevice instuctions ae available and povide guidelines fo lubication and ecommended lubicants. Whee significant thust s ae to be caied, lubication becomes moe citical and Link-elt ea Division should be consulted. Imposed adial s should not exceed.25. Whee high adial s, high speeds, thust s o vibatoy s ae unavoidable, consult the Link-elt ea Division. Fixed and Expansion Mounting: The design of cylindical olle beas and the optional featues pemits fixed o expansion mounting by vaying the numbe of ibs used with each bea. bea with no ibs on the (i.e. M1200TV of MU1200X) is an expansion type bea as the olle set is fee to shift axially on one aceway. The opposite bea must then be a locating bea. Many othe aangements ae possible using these same pinciples. ae should always be taken not to foce beas to thust against o away fom each othe du mounting o opeation.

Fo this pocedue, consult Link-elt ea Division. Waning: The eliability built into all Link-elt beas can be ealized in sevice only when they ae coectly selected and popely installed, potected and maintained. The coect selection of beas equies that the magnitude and natue of all s, speeds, alignment, mounting, ope equiements, and maintenance be adequately consideed. The selection of mateials fo and design of housings, shafting, fastenes, seals, and accessoies as well as povisions fo installation and maintenance must follow good enginee pinciples. Housings and coves must be designed to safely handle the adial and axial s involved. dequate space must be povided in the housing and coves fo a supply of lubicant. Seals must be povided that will satisfactoily cope with the envionmental conditions. Shaft size and housing boe size tables show ecommended fitting pactices, and should be followed stictly to assue a successful mounting aangement. Sevice instuctions ae povided with shipments of beas and ae available on equest. These instuctions povide detailed infomation to aid in pope installation, opeation, and maintenance, and should be caefully ead and followed.
