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.

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.
Installation: Use appropriate tools (hydraulic press, bearing installation sleeve) for even installation. Ensure proper alignment and consider pre-load adjustment for optimal performance.
Maintenance: Regular lubrication with lithium-based grease (fill 1/3 to 1/2 of bearing space). Monitor temperature (60-80°C normal range) and watch for abnormal vibration or noise. Replace lubricant when contaminated.
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.
