    About the bearing

    D 90d 40B 23
    d×D×Bsize 40 × 90 × 23mm

    Deep groove ball bearing 6308. Under GOST the same bearing is designated 308.

    Frequently asked questions

    What is 308?

    It is the same bearing under GOST 3189-89: 308 corresponds to the ISO base 6308. Size 40 × 90 × 23 mm, a full equivalent of 6308.

    Will 6308 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.
