Low Friction 6004 Ball Bearing GCr15 Ball Bearing 20x42x12 For Motors, Automotive And Household Appliances

The 6004 deep groove ball bearing is a widely-used and highly versatile component in mechanical engineering. Renowned for its simple yet robust design, low-friction operation, and ability to handle various loads, this bearing is essential across numerous industries.

Inner Ring and Outer Ring: Precision-crafted rings with deep, precisely-machined raceways. The inner ring fits snugly onto 20mm shafts, while the outer ring withstands external forces with a 42mm outer diameter.

Rolling Elements and Cage: High-precision steel balls made from top-grade bearing steel provide excellent wear resistance. The sheet metal cage maintains proper ball spacing and guides smooth rotation.

Sealing Structure (Optional): Available with rubber seals (6004-2RS type) for protection against dust and moisture, or metal shields for applications requiring higher speeds with basic protection.

• High Radial Load Capacity: Handles significant radial loads with even force distribution
• Axial Load Accommodation: Supports axial loads in both directions
• Low Friction & High-Speed Capability: Operates at 18,000-24,000 rpm with minimal energy consumption
• Quiet Operation: Optimized for low-noise and low-vibration performance

Rings and Balls: High-grade bearing steel with excellent mechanical properties, processed through vacuum degassing, cold-heading, and heat treatment for superior strength and durability.

Cage Material: Sheet metal for optimal strength and thermal conductivity, with non-metallic options available for specialized applications.

• Industrial Machinery: Machine tool spindles, conveyor systems
• Electric Motors: Medium-power range motors requiring smooth rotation
• Automotive Industry: Water pumps, transmission systems
• Household Appliances: Washing machines, fans, and other quiet-operation devices

The 6004 deep groove ball bearing delivers reliable performance across diverse applications, from industrial machinery to household appliances. Its robust design, material quality, and maintenance-friendly features make it an essential component for efficient mechanical systems.
