    Thrust ball bearing 51204. Under GOST the same bearing is designated 8204.

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

    Frequently asked questions

    What is 8204?

    It is the same bearing under GOST 3189-89: 8204 corresponds to the ISO base 51204. Size 20 × 40 × 14 mm, a full equivalent of 51204.

    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.
