About the bearing

C0static 275kN

Tapered roller bearing 32311. Under GOST the same bearing is designated 7611.

C, C₀ and limiting speed 4,400 rpm: KG data. Another brand publishes its own figures, so compare them against that brand’s catalogue.

Frequently asked questions

What is 7611?

It is the same bearing under GOST 3189-89: 7611 corresponds to the ISO base 32311. Size 55 × 120 × 45.5 mm, a full equivalent of 32311.

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.
