The 6200, 6300, and 6400 Series Deep Groove Ball Bearings are high-performance engineered components designed for maximum versatility and industrial efficiency. Featuring a streamlined, compact architecture with a precision-machined deep arc-shaped raceway, these bearings are optimized to save space while providing exceptional radial load-bearing capacity and moderate bidirectional axial support, eliminating the need for separate thrust bearings in most mechanical assemblies.
Crafted from premium-grade GCr15 bearing steel and treated with advanced precision heat processes, our Deep Groove Ball Bearings ensure superior wear resistance and an extended fatigue lifecycle. Whether deployed in high-speed environments exceeding 10,000 r/min or operating under harsh industrial conditions via specialized sealed and shielded configurations, these series deliver the reliable stability and cost-effectiveness essential for modern manufacturing and machinery.

Frequently Asked Questions
Shielded (ZZ) bearings are better for high-speed applications with low dust, while Sealed (2RS) bearings provide superior protection against moisture and dust in harsh environments.
Common causes include lubricant contamination, misalignment of the shaft, or improper fit tolerances leading to ring slipping.
Yes, they are primarily designed for radial loads but can handle moderate bidirectional axial loads without requiring additional thrust bearings.
Normal operating temperature should generally remain below 70°C. Temperatures exceeding this may indicate overloading or insufficient lubrication.
For marine or chemical environments, stainless steel versions are highly recommended to prevent rust and corrosion pits.
Unused bearings should be stored in a dry, cool place in their original intact packaging to avoid moisture and corrosive substances.
