    About the bearing

    Cdynamic 44.8kN
    C0static 16kN

    Self-aligning ball bearing 2308. Under GOST the same bearing is designated 1608.

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

    Frequently asked questions

    What is 1608?

    It is the same bearing under GOST 3189-89: 1608 corresponds to the ISO base 2308. Size 40 × 90 × 33 mm, a full equivalent of 2308.

    Will 2308 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.
