About the bearing

D 40d 17B 12
d×D×Bsize 17 × 40 × 12mm

Angular contact ball bearing 7203 C. Under GOST the same bearing is designated 36203.

Frequently asked questions

What is 36203?

It is the same bearing under GOST 3189-89: 36203 corresponds to the ISO base 7203 C. Size 17 × 40 × 12 mm, a full equivalent of 7203 C.

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.
