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

Frequently asked questions

What is 3056306?

It is the same bearing under GOST 3189-89: 3056306 corresponds to the ISO base 3306. Size 30 × 72 × 30.2 mm, a full equivalent of 3306.

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.
