The Auburn Advantage
Thrust Bearings
T-200-RG: Enclosed, Double Grooved Raceways
This enclosed style round groove series is recommended for use where maximum carrying capacity is desired but thickness space available is limited. The balls are retained between two hardened steel races banded together by a mild steel or brass sleeve on the outside diameter. The double grooved raceways provide increased capacity without increasing the overall thickness of the bearing.
Auburn Enclosed Style T-200-RG Ball Thrust Bearing is recommended for use where maximum carrying capacity is desired but thickness space is limited. It is self-contained; the two races and balls are held together as a unit by the outside sleeve.

Ball Thrust Bearing Mounting Instructions
Generally installed with the fitted bore “A”
centered on the shaft and rotating with it, the clearance bore “A'”
(the race with the sleeve attached to it) seats against a fixed part of the machine and remains stationary. If installed in a recess, a clearance of 1/8" or more should be left around the outside diameter “B”, in case the shaft wears in its journal bearings. If this should happen, the clearance you allowed on the outside diameter will prevent the balls from wedging.
