Deep groove ball bearing 6301. Under GOST the same bearing is designated 301.

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

Frequently asked questions

What is 301?

It is the same bearing under GOST 3189-89: 301 corresponds to the ISO base 6301. Size 12 × 37 × 12 mm, a full equivalent of 6301.

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.
