About the bearing

d×D×Bsize 55 × 120 × 43mm
mweight 2.07kg

Self-aligning ball bearing 2311. Under GOST the same bearing is designated 1611.

M: Z&S data. Another brand publishes its own figures, so compare them against that brand’s catalogue.

Frequently asked questions

What is 1611?

It is the same bearing under GOST 3189-89: 1611 corresponds to the ISO base 2311. Size 55 × 120 × 43 mm, a full equivalent of 2311.

Will 2311 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.
