Thrust ball bearing 51220. Under GOST the same bearing is designated 8220.

C, C₀, m: CT data. Another brand publishes its own figures, so compare them against that brand’s catalogue.

Frequently asked questions

What is 8220?

It is the same bearing under GOST 3189-89: 8220 corresponds to the ISO base 51220. Size 100 × 150 × 38 mm, a full equivalent of 51220.

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.
