Tapered roller bearing 30230. Under GOST the same bearing is designated 7230.

Frequently asked questions

What is 7230?

It is the same bearing under GOST 3189-89: 7230 corresponds to the ISO base 30230. Size 150 × 270 × 49 mm, a full equivalent of 30230.

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.
