About the bearing

D 47d 17B 14
d×D×Bsize 17 × 47 × 14mm

Deep groove ball bearing 6303-RS, design D: contact seal on one side. Under GOST the same bearing is designated 160303.

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 160303?

It is the same bearing under GOST 3189-89: 16 — contact seal on one side, 0303 corresponds to the ISO base 6303. Size 17 × 47 × 14 mm, a full equivalent of 6303-RS.

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.
