Inner Ring (IR) Timken IR-809640

Описание

Ideal choice where the shaft is not practical to use as inner raceway. Designed to meet established inch tolerances. Maximum shaft fillet radius cannot exceed inner-ring bore chamfer as shown. Optional centralized lubrication groove (bore) or through hole available – specify when ordering. Designed to be axially clamped against shoulder for loose transition fit on shaft. After mounting, for tight transition fit (keeping inner ring from rotating relative to shaft), inner-ring O.D. must not exceed raceway diameter on matching bearing. After mounting, if O.D. of inner ring exceeds the required raceway diameter for matching bearing, ring should be ground to proper diameter while mounted on shaft. Unmarked end of inner ring to be assembled against the shaft shoulder to ensure clearing the maximum allowable shaft fillet as indicated in tables shown. Specifications Shaft Diameter 5 in Max.
