Frequently asked questions

What is 1220?

It is the same bearing under GOST 3189-89: 1220 corresponds to the ISO base 1220. Size 100 × 180 × 34 mm, a full equivalent of 1220.

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.
