    Details

    what this bearing is, questions

    About the bearing

    d×D×Bsize 55 × 100 × 21mm
    Cdynamic 27.6kN

    Self-aligning ball bearing 1211. Under GOST the same bearing is designated 1211.

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

    Frequently asked questions

    What is 1211?

    It is the same bearing under GOST 3189-89: 1211 corresponds to the ISO base 1211. Size 55 × 100 × 21 mm, a full equivalent of 1211.

    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.
