    Deep groove ball bearing 61904. Under GOST the same bearing is designated 1000904.

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

    Frequently asked questions

    What is 1000904?

    It is the same bearing under GOST 3189-89: 1000904 corresponds to the ISO base 61904. Size 20 × 37 × 9 mm, a full equivalent of 61904.

    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.
