Frequently asked questions

What is 304?

It is the same bearing under GOST 3189-89: 304 corresponds to the ISO base 6304. Size 20 × 52 × 15 mm, a full equivalent of 6304.

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.
