    Tapered roller bearing 30318. Under GOST the same bearing is designated 7318.

    C, C₀, m and limiting speed 2,600 rpm: Z&S data. Another brand publishes its own figures, so compare them against that brand’s catalogue.

    Frequently asked questions

    What is 7318?

    It is the same bearing under GOST 3189-89: 7318 corresponds to the ISO base 30318. Size 90 × 190 × 46.5 mm, a full equivalent of 30318.

    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.
