SELECTION CONTEXT
Match the bearing
to its duty.
51102 belongs to the thrust ball bearings family. Its reference envelope is 15 mm bore, 28 mm outside diameter and 9 mm overall width or height.
Thrust ball bearings support axial load rather than radial load. Confirm load direction, shaft and housing washers, alignment and minimum load requirements.
For a manufacturing enquiry, provide the complete designation and operating conditions. Matching the dimensional envelope alone does not confirm interchangeability or equivalent performance.
Is the same size a direct replacement?
No. Matching 15 × 28 × 9 mm establishes the boundary dimensions. The full designation, tolerances, clearance, contact angle or roller arrangement, seals, cage, lubrication and performance must also be checked.
