Tapered roller bearing 30320. Under GOST the same bearing is designated 7320.

C, C₀, m: NTE data. Another brand publishes its own figures, so compare them against that brand’s catalogue.

Frequently asked questions

What is 7320?

It is the same bearing under GOST 3189-89: 7320 corresponds to the ISO base 30320. Size 100 × 215 × 51.5 mm, a full equivalent of 30320.

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.
