Tapered roller bearing 30313. Under GOST the same bearing is designated 7313.

C, C₀, m and limiting speed 3,700 rpm: KG data. Another brand publishes its own figures, so compare them against that brand’s catalogue.

Frequently asked questions

What is 7313?

It is the same bearing under GOST 3189-89: 7313 corresponds to the ISO base 30313. Size 65 × 140 × 36 mm, a full equivalent of 30313.

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.
