    About the bearing

    d×D×Bsize 55 × 100 × 21mm

    Self-aligning ball bearing 1211 K. Under GOST the same bearing is designated 111211.

    Frequently asked questions

    What is 111211?

    It is the same bearing under GOST 3189-89: 111211 corresponds to the ISO base 1211 K. Size 55 × 100 × 21 mm, a full equivalent of 1211 K.

    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.
