Angular contact ball bearing 7210 B. Under GOST the same bearing is designated 66210.

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

Frequently asked questions

What is 66210?

It is the same bearing under GOST 3189-89: 66210 corresponds to the ISO base 7210 B. Size 50 × 90 × 20 mm, a full equivalent of 7210 B.

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.
