6306 ZZ CT deep groove ball bearing 30x72x19

Industrial applications

The 6306 ZZ CT bearing is designed for industrial systems requiring higher load capacity and stable performance at medium to high rotational speeds. It is widely used in electric motors, pumps, gearboxes, fans, and industrial machinery.

Its metal shield design makes it suitable for environments with moderate contamination, where speed and efficiency are key factors.

Construction and design

6306 ZZ CT is a single row deep groove ball bearing equipped with double metal shields (ZZ) on both sides. These shields protect against solid contaminants while maintaining lower friction compared to rubber-sealed bearings.

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