    Angular contact ball bearing 3203. Under GOST the same bearing is designated 3056203.

    C, C₀, m: CT data. Another brand publishes its own figures, so compare them against that brand’s catalogue.

    Frequently asked questions

    What is 3056203?

    It is the same bearing under GOST 3189-89: 3056203 corresponds to the ISO base 3203. Size 17 × 40 × 17.5 mm, a full equivalent of 3203.

    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.
