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

Frequently asked questions

What is 208?

It is the same bearing under GOST 3189-89: 208 corresponds to the ISO base 6208. Size 40 × 80 × 18 mm, a full equivalent of 6208.

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.
