Deep groove ball bearing 6303-2RS, design 2RS: contact seals on both sides. Under GOST the same bearing is designated 180303.

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 180303?

It is the same bearing under GOST 3189-89: 18 — contact seals on both sides, 0303 corresponds to the ISO base 6303. Size 17 × 47 × 14 mm, a full equivalent of 6303-2RS.

Will 6303 2RS 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.
