6303 ZZ CT deep groove ball bearing 17x47x14

Construction and design

6303 ZZ CT is a single row deep groove ball bearing equipped with double metal shields (ZZ) on both sides. These shields protect the internal components from solid contaminants while allowing higher rotational speeds compared to rubber-sealed bearings.

Precision-machined raceways and rolling elements ensure smooth operation, low friction, and stable performance. The bearing is factory lubricated and ready for immediate installation.
