About the bearing

Tapered roller bearing 31320. Under GOST the same bearing is designated 1027320.

Frequently asked questions

What is 1027320?

It is the same bearing under GOST 3189-89: 1027320 corresponds to the ISO base 31320. Size 100 × 215 × 56.5 mm, a full equivalent of 31320.

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.
