    Deep groove ball bearing 6313. Under GOST the same bearing is designated 313.

    C, C₀, m and limiting speed 6,700 rpm: KG data. Another brand publishes its own figures, so compare them against that brand’s catalogue.

    Frequently asked questions

    What is 313?

    It is the same bearing under GOST 3189-89: 313 corresponds to the ISO base 6313. Size 65 × 140 × 33 mm, a full equivalent of 6313.

    Will 6313 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.
