Frequently asked questions

What is 3056309?

It is the same bearing under GOST 3189-89: 3056309 corresponds to the ISO base 3309. Size 45 × 100 × 39.7 mm, a full equivalent of 3309.

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.
