Deep Groove Ball Bearing
Our deep groove ball bearings are made of high-quality bearing steel and have the characteristics of high speed, low friction and long life. Such products of dsr are widely used in motors, automobiles, industrial equipment and other fields, and are the core transmission components of rotating machinery.
- High speed performance – optimized raceway design supports ultra-high speed operation
- Low noise operation – smooth operation, noise is lower than the industry standard.
- Long service life – high-quality GCr15 bearing steel, heat-treated and precision-ground, life is increased by 30%.
- Sealed and dustproof – standard rubber seal (RS/2RS) or metal dust cover (ZZ), effectively preventing dust and dirt.

Product Description
Our deep groove ball bearings are made of high-quality GCr15 bearing steel and are manufactured through multiple processes such as precision forging, heat treatment, and grinding. The optimized raceway curve design ensures that the bearing maintains low friction and low heat generation characteristics during high-speed operation.
We offer three models: open (without seal), rubber seal (RS/2RS), and metal dust cover (ZZ) to meet different working conditions. All bearings undergo vibration testing, clearance testing, and lifespan testing before leaving the factory to ensure stable and reliable performance.
