About the bearing

Tapered roller bearing 30210. Under GOST the same bearing is designated 7210.

M: BBC-R data. Another brand publishes its own figures, so compare them against that brand’s catalogue.

Frequently asked questions

What is 7210?

It is the same bearing under GOST 3189-89: 7210 corresponds to the ISO base 30210. Size 50 × 90 × 21.75 mm, a full equivalent of 30210.

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.
