Frequently asked questions

What is 1218?

It is the same bearing under GOST 3189-89: 1218 corresponds to the ISO base 1218. Size 90 × 160 × 30 mm, a full equivalent of 1218.

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.
