6204 ZZ CBK deep groove ball bearing 20x47x14 mm

Application in industrial machinery and drives

6204 ZZ CBK is a single row deep groove ball bearing with dimensions 20x47x14 mm, designed for versatile use in industrial and automotive applications. As part of the widely used 6204 series, it provides reliable shaft support in electric motors, pumps, gearboxes and production machinery.

This 20x47x14 ball bearing is commonly installed in drive systems requiring stable rotation, moderate load capacity and consistent performance at medium to high speeds. When integrated into a complete bearing unit and mounted in a suitable bearing housing, it ensures accurate shaft alignment, reduced vibration and extended service life in industrial environments.

Design and ZZ metal shields

The 6204 ZZ CBK deep groove ball bearing features double sided metal shields marked ZZ. These shields protect the internal raceways and rolling elements from contamination while retaining the factory filled grease inside the bearing.

The internal construction includes an inner ring, outer ring, steel balls and a cage that maintains proper spacing between the rolling elements. The deep groove geometry allows the bearing to carry radial loads and moderate axial loads in both directions. Precision manufacturing ensures uniform load distribution and smooth running characteristics even under continuous operation.
