    Frequently asked questions

    What is 7310?

    It is the same bearing under GOST 3189-89: 7310 corresponds to the ISO base 30310. Size 50 × 110 × 29.25 mm, a full equivalent of 30310.

    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.
