A rotary apparatus (10), such as a pneumatic motor, comprises an end plate (20) having a race cavity (22), a main rotor (30) with a stub shaft (32) extending from one end, and a bearing (40), which includes an outer race (42) seated in the race cavity (22) and an inner race (44) having a central bore (50). The stub shaft (32) is fitted into the central bore (50) with a frictional fit. The threaded shank (62) of a screw (60) is threaded into a threaded socket (80) in the stub shaft (32) and is used to draw the stub shaft (32) into the central bore (50) with a washer (70) bearing against a head (64) of the screw, and against the inner race (44), whereby a controlled gap (g) can be provided between an outer surface (36) of the main rotor (30) and an inner surface (26) of the end plate (20). <IMAGE> |
