    About the bearing

    d×D×Bsize 45 × 100 × 25mm
    Cdynamic 125kN

    Spherical roller bearing 21309.

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

    Frequently asked questions

    Will 21309 C3 fit instead?

    Same size, clearance greater than normal. C3 is used where the bearing runs hot or sits on the shaft with an interference fit. If the old bearing is not marked C3, take this one.

    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.
