About the bearing

d×D×Bsize 25 × 52 × 15mm
Cdynamic 14.3kN

Self-aligning ball bearing 1205 K. Under GOST the same bearing is designated 111205.

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

Frequently asked questions

What is 111205?

It is the same bearing under GOST 3189-89: 111205 corresponds to the ISO base 1205 K. Size 25 × 52 × 15 mm, a full equivalent of 1205 K.

Will 1205 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.
