6005-ZZ Ball Bearing

The 6005-ZZ Ball Bearing is a deep groove ball bearing with double metal shields engineered for applications requiring low rolling resistance, fast rotational response, and continuous operation in compact equipment.

Measuring 25x47x12mm, this bearing belongs to the 6000 series, recognized for combining lightweight construction, rotational efficiency, and dependable high-speed performance. Manufactured from chrome steel and supplied factory pre-lubricated, the ZZ configuration uses metal shields on both sides to help retain grease without compromising thermal efficiency during high-RPM operation.

Applications for the 6005-ZZ

The 6005-ZZ is commonly used in lightweight equipment and compact industrial systems, including:

• Small electric motors
• HVAC equipment
• Power tools
• Automated machinery
• Compact fans
• Light agricultural equipment
• Industrial pulleys
• Continuous-motion equipment

The 6000 series is widely selected when a system requires reduced weight, lower friction, and efficient rotation.

Features of the 6005-ZZ Ball Bearing

Metal shields for high-speed operation

Metal shields help reduce entry of light particles while maintaining low rolling resistance in high-RPM applications.

Ultra-compact structure

With a width of only 12mm, this bearing is suitable for systems with limited installation space.

Improved thermal efficiency

The ZZ configuration typically generates less friction than rubber-sealed models, supporting reduced operational heat.

Smooth and stable rotation

Deep groove geometry supports quieter operation, lower vibration, and dependable continuous-duty performance.

Chrome steel construction

Chrome steel provides dependable mechanical strength and durability for light and medium industrial applications.

When to Use a ZZ Bearing

ZZ bearings are commonly recommended for:

• High-speed equipment
• Dry environments
• Compact systems
• Applications requiring lower rolling resistance
• Machinery with limited moisture exposure

2RS bearings are generally preferred when stronger sealing protection is required.

Usage Recommendations

To improve bearing performance:

• Use proper aligned installation
• Avoid excessive impact loads
• Monitor operating temperature
• Control abnormal vibration
• Keep the system clean
