About the bearing

Deep groove ball bearing 6304. Under GOST the same bearing is designated 304.

Frequently asked questions

What is 304?

It is the same bearing under GOST 3189-89: 304 corresponds to the ISO base 6304. Size 20 × 52 × 15 mm, a full equivalent of 6304.

Will 6304 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.
