    Thrust ball bearing 51305. Under GOST the same bearing is designated 8305.

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

    Frequently asked questions

    What is 8305?

    It is the same bearing under GOST 3189-89: 8305 corresponds to the ISO base 51305. Size 25 × 52 × 18 mm, a full equivalent of 51305.

    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.
