Deep groove ball bearing 6303. Under GOST the same bearing is designated 303.

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

Frequently asked questions

What is 303?

It is the same bearing under GOST 3189-89: 303 corresponds to the ISO base 6303. Size 17 × 47 × 14 mm, a full equivalent of 6303.

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.
