    Thrust ball bearing 51211. Under GOST the same bearing is designated 8211.

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

    Frequently asked questions

    What is 8211?

    It is the same bearing under GOST 3189-89: 8211 corresponds to the ISO base 51211. Size 55 × 90 × 25 mm, a full equivalent of 51211.

    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.
