About the bearing

Tapered roller bearing 30203. Under GOST the same bearing is designated 7203.

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

Frequently asked questions

What is 7203?

It is the same bearing under GOST 3189-89: 7203 corresponds to the ISO base 30203. Size 17 × 40 × 13.25 mm, a full equivalent of 30203.

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.
