    About the bearing

    d×D×Tsize 17 × 30 × 9mm
    Cdynamic 11.4kN

    Thrust ball bearing 51103. Under GOST the same bearing is designated 8103.

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

    Frequently asked questions

    What is 8103?

    It is the same bearing under GOST 3189-89: 8103 corresponds to the ISO base 51103. Size 17 × 30 × 9 mm, a full equivalent of 51103.

    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.
