Thrust ball bearing 51216 consists of two precision washers and a ball complement spaced by bronze cage, this type of bearing can be supplied with or without radius ball grooves in the rings. The bearing with housing washer which has spherical mounting surface is self-aligning, which can reduce the effects of mounting error.

Single direction bearings can carry axial load in one direction, and double direction bearings can carry axial load in two directions, if you want to choose thrust ball bearings, feel free to contact US





1. Available in two designs: single direction and double direction.

2. To accommodate initial misalignments in an assembly both designs are available with spherical aligning seats or aligning seat washers.

3. High quality steel-ultra clean steel to extend bearing life by up to 80%.

4. Advanced Grease Technology – our lubricants that can extend grease life and performance.
