About the bearing

d×D×Hsize 100 × 135 × 25mm

Thrust ball bearing 51120. Under GOST the same bearing is designated 8120.

Frequently asked questions

What is 8120?

It is the same bearing under GOST 3189-89: 8120 corresponds to the ISO base 51120. Size 100 × 135 × 25 mm, a full equivalent of 51120.

Can I fit another brand instead of this bearing?

Without checking, only an exact equivalent: the size, seal, clearance and design match according to the brand’s catalogue. Positions with the same geometry differ in seal, clearance or design, and each one says so in the equivalents block. Load ratings differ between manufacturers, so for a heavily loaded unit compare C.
