    About the bearing

    D 30d 17B 7
    d×D×Bsize 17 × 30 × 7mm

    Deep groove ball bearing 61903. Under GOST the same bearing is designated 1000903.

    Frequently asked questions

    What is 1000903?

    It is the same bearing under GOST 3189-89: 1000903 corresponds to the ISO base 61903. Size 17 × 30 × 7 mm, a full equivalent of 61903.

    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.
