1 Stuctue an Featues Stuctues of eele Rolle Beains with Sepaable ae eele Rolle Beains with Sepaable ae - Without Inne Rin eele Rolle Beains with Sepaable ae - With Inne Rin In eele Rolle Beains with Sepaable ae, the inne in, oute in an eele Rolle ae ae combine, an they can be sepaate easily. This type has a simple stuctue with hih accuacy. In aition, the aial cleaance can be feely chosen by selectin an combinin these component pats. As eele Rolle aes ae use, these beains have excellent otational pefomance. These beains ae most suitable fo mass-pouction hih accuacy poucts such as machine tools, textile machiney, an pintin machines.

As shown in the section, "esin of shaft an housin" on pae A44, any esie aial intenal cleaance can be selectey combinin a shaft which is heat-teate an finishey inin. eele Rolle Beains with Sepaable ae - With Inne Rin These beains ae mae to the cleaance shown in Table 9 on pae A. When especially hih accuacy is equie, it is possible to supply semi-finishe inne ins which have a finishin allowance on thei outsie iamete so that they can be oun afte bein pess-fitte to shafts. The ientification numbe of eele Rolle Beains with Sepaable ae consists of a moel coe, imensions, any supplemental coes an a classification symbol. The aanement examples ae as follows.

Fit Recoene fits fo eele Rolle Beains with Sepaable ae ae shown in Tables 2 to on paes A4 an A. Lubication eele Rolle Beains with Sepaable ae ae not povie with pepacke ease. Pefom pope lubication fo use. Usin them without lubication will incease the wea of the ollin contact sufaces an shoten thei lives. Oil Hole The ouble-ow type oute ins have both an oil hole an an oil oove, but the sinle-ow type oute ins o not. When oute ins with an oil hole ae equie, attach "-OH" befoe the cleaance symbol in the ientification numbe, an when oute ins with both an oil hole an an oil oove ae equie, attach "-OG" to the same position. Example: AF - OH 2 P6 When oute ins with multiple oil holes o inne ins with oil hole(s) ae equie, please contact. Mountin examples of eele Rolle Beains with Sepaable ae ae shown in Fi.. When mountin eele Rolle Beains with Sepaable ae, it is necessay to locate the neele cae axially. The neele cae is uiey shoules of the shaft an housin o by sie plates, an thei uie sufaces must be heat-teate an finishey inin at iht anles to the shaft cental axis. imensions elate to mountin ae shown in the table of imensions.
