    Details

    what this bearing is, questions

    About the bearing

    d×D×Bsize 55 × 120 × 43mm
    Cdynamic 270kN

    Spherical roller bearing 22311 K. Under GOST the same bearing is designated 153611.

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

    Frequently asked questions

    What is 153611?

    It is the same bearing under GOST 3189-89: 153611 corresponds to the ISO base 22311 K. Size 55 × 120 × 43 mm, a full equivalent of 22311 K.

    Will 22311 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.
