About the bearing

Angular contact ball bearing 7011 C. Under GOST the same bearing is designated 36111.

Frequently asked questions

What is 36111?

It is the same bearing under GOST 3189-89: 36111 corresponds to the ISO base 7011 C. Size 55 × 90 × 18 mm, a full equivalent of 7011 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.
