    Deep groove ball bearing 6004. Under GOST the same bearing is designated 104.

    C, C₀, m and limiting speed 24,000 rpm: KG data. Another brand publishes its own figures, so compare them against that brand’s catalogue.

    Frequently asked questions

    What is 104?

    It is the same bearing under GOST 3189-89: 104 corresponds to the ISO base 6004. Size 20 × 42 × 12 mm, a full equivalent of 6004.

    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.
