Deep groove ball bearing No name 6003 ZZ – double metal shields, single row

Deep groove ball bearing No name 6003 ZZ is a single-row radial bearing with double metal shields on both sides. Designed to support radial loads and moderate axial forces in rotating assemblies, this 6003 ZZ bearing provides sealed protection against dust and light contamination while maintaining low friction and reliable rotation. Its compact design and common dimensions make it suitable for a wide range of industrial and consumer applications such as electric motors, gearboxes, pumps and fans.

Advantages

The double metal shields (ZZ) provide effective protection against dust and small particles while enabling higher rotational speeds compared with fully sealed designs. As a single-row deep groove configuration, the bearing offers low friction, simple mounting, and consistent performance under radial loading. The metal shields are non-contact or light-contact depending on design, which helps reduce wear and heat generation and extends operational life in typical working conditions.

Suitable for

• Electric motors and generators
• Pumps and compressors
• Gearboxes and transmissions
• Fans, blowers and ventilation systems
• General machinery and conveyor rollers

Key specifications

• Bearing type: deep groove ball bearing, single row
• Shielding: double metal shields on both sides (ZZ)
• Primary function: supports radial loads and moderate axial loads
• Application style: suitable for rotating shafts in motors, gearboxes and pumps
• Operating characteristic: low friction profile for standard-speed operation

How to use

Select the correct shaft and housing fit according to the machine’s design and the bearing’s dimensional standard. Clean mating surfaces before pressing the bearing into position; apply even axial force on the inner or outer ring as specified by the equipment manufacturer to avoid bearing seat damage. For bearings with metal shields, use appropriate lubricants recommended for shielded bearings—usually a compatible grease applied at assembly or pre-lubricated units as supplied. Check for proper axial clearance, secure bearing retaining features if required, and ensure correct alignment of the shaft and housing before putting the assembly into service.

Usage recommendations

Use this 6003 ZZ bearing in environments with dust or light contamination where metal-shielded protection is sufficient. Avoid prolonged exposure to heavy contamination, water ingress, or corrosive chemicals without additional sealing. Periodically inspect operating temperature and vibration; relubricate or replace the bearing according to equipment maintenance schedules and load conditions.
