Deep groove ball bearing 6315-ZZ, design ZZ: metal shields on both sides. Under GOST the same bearing is designated 80315.

Frequently asked questions

How does 2RS differ from ZZ?

2RS has rubber seals that touch the inner ring and keep out dust and water better, which is the usual choice for field machinery. ZZ has metal shields that do not touch, allow higher speeds, and protect against dirt less well.

What is 80315?

It is the same bearing under GOST 3189-89: 8 — metal shields on both sides, 0315 corresponds to the ISO base 6315. Size 75 × 160 × 37 mm, a full equivalent of 6315-ZZ.

Will 6315 ZZ 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.
