About the bearing

d×D×Bsize 35 × 80 × 31mm
Cdynamic 39.7kN

Self-aligning ball bearing 2307. Under GOST the same bearing is designated 1607.

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

Frequently asked questions

What is 1607?

It is the same bearing under GOST 3189-89: 1607 corresponds to the ISO base 2307. Size 35 × 80 × 31 mm, a full equivalent of 2307.

Will 2307 C3 fit instead?

Same size, clearance greater than normal. C3 is used where the bearing runs hot or sits on the shaft with an interference fit. If the old bearing is not marked C3, take this one.

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.
