Axial load or thrust bearing.

Outer diameter 42mm, inner diameter 25mm, thickness; 11mm.

In the horizontal position the cage should go on top.

I suggest assambling it upside down and than carefully turn the whole assambly around.

I would not recommend it for critical use, high precision or excessive load cases. But I personaly do think they are very usefull and adequate most of the time.

Don't forget lube before use.
