Tapered roller bearing 31307. Under GOST the same bearing is designated 27307.

C, C₀, m and limiting speed 6,000 rpm: Z&S data. Another brand publishes its own figures, so compare them against that brand’s catalogue.

Frequently asked questions

What is 27307?

It is the same bearing under GOST 3189-89: 27307 corresponds to the ISO base 31307. Size 35 × 80 × 22.75 mm, a full equivalent of 31307.

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.
