About the bearing

d×D×Bsize 90 × 190 × 43mm

Deep groove ball bearing 6318. Under GOST the same bearing is designated 318.

Frequently asked questions

What is 318?

It is the same bearing under GOST 3189-89: 318 corresponds to the ISO base 6318. Size 90 × 190 × 43 mm, a full equivalent of 6318.

Will 6318 C3 fit instead?

Same size, clearance greater than normal. C3 is used where the bearing runs hot or sits on the shaft with an interference fit. If the old bearing is not marked C3, take this one.

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.
