About the bearing

d×D×Hsize 90 × 155 × 50mm

Thrust ball bearing 51318. Under GOST the same bearing is designated 8318.

Frequently asked questions

What is 8318?

It is the same bearing under GOST 3189-89: 8318 corresponds to the ISO base 51318. Size 90 × 155 × 50 mm, a full equivalent of 51318.

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.
