    Frequently asked questions

    What is 1203?

    It is the same bearing under GOST 3189-89: 1203 corresponds to the ISO base 1203. Size 17 × 40 × 12 mm, a full equivalent of 1203.

    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.
