    Deep groove ball bearing 6411. Under GOST the same bearing is designated 411.

    C, C₀, m and limiting speed 7,000 rpm: KG data. Another brand publishes its own figures, so compare them against that brand’s catalogue.

    Frequently asked questions

    What is 411?

    It is the same bearing under GOST 3189-89: 411 corresponds to the ISO base 6411. Size 55 × 140 × 33 mm, a full equivalent of 6411.

    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.
