Product Description

The 51202 is an NSK thrust ball bearing from the single-direction 51202 series, standard flat-seat type: 15 mm shaft-washer bore, 32 mm housing-washer outer diameter, 12 mm height. Basic dynamic load rating Ca is 16.7 kN and basic static load rating C0a is 24.8 kN (NSK official catalog CAT. No. E1103d). Thrust ball bearings carry pure axial load in one direction only — no radial capacity — and are common in worm-gear reducers, screw jacks and valve actuator shafts where low-speed axial thrust must be supported.
