    Deep groove ball bearing 623. Under GOST the same bearing is designated 23.

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

    Frequently asked questions

    What is 23?

    It is the same bearing under GOST 3189-89: 23 corresponds to the ISO base 623. Size 3 × 10 × 4 mm, a full equivalent of 623.

    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.
