Thrust ball bearings
51100 and 51200 series single direction thrust ball bearings for axial loads in a compact space.
A thrust ball bearing has two flat washers with a ring of balls between them. It takes axial load only, in one direction, and is used where a shaft pushes along its own length: steering knuckles, vehicle and hydraulic jacks, clutch parts, vertical shafts and rotary tables.
The 51100 series is the light series and the 51200 series is taller and stronger for the same bore. Tap any number below for its exact size.

Frequently asked questions
What is the difference between 51105 and 51205?
Both have a 25 mm bore. The 51205 is larger (47 mm OD, 15 mm high) than the 51105 (42 mm OD, 11 mm high), so it carries more axial load.
