Frequently asked questions

What is 27311?

It is the same bearing under GOST 3189-89: 27311 corresponds to the ISO base 31311. Size 55 × 120 × 31.5 mm, a full equivalent of 31311.

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.
