About the bearing

D 130d 60B 31
d×D×Bsize 60 × 130 × 31mm

Deep groove ball bearing 6312-2RS, design DDU: contact seals on both sides. Under GOST the same bearing is designated 180312.

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 180312?

It is the same bearing under GOST 3189-89: 18 — contact seals on both sides, 0312 corresponds to the ISO base 6312. Size 60 × 130 × 31 mm, a full equivalent of 6312-2RS.

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.
