420, 304 and 440C Stainless Steel Bearings – What’s The Difference?

Different grades of stainless steel bearings are engineered to adapt to distinct operating environments, with unique performance characteristics and application scenarios.

420 stainless steel bearings feature excellent hardness and moderate corrosion resistance. They are extensively applied in general mechanical equipment and automotive component fields, delivering stable comprehensive performance under conventional working conditions.

304 stainless steel bearings boast outstanding corrosion resistance and superior hygienic properties. Free from contamination and rust-prone issues, they serve as the optimal choice for food processing machinery and medical equipment applications.

440C stainless steel bearings exhibit exceptional mechanical strength, capable of enduring higher loads and supporting high-speed operation compared with ordinary stainless steel bearings.

We provide personalized customization services for bearing sizes and structural specifications to meet diverse customer demands. Selecting the most suitable stainless steel bearing grade effectively reduces operational costs and significantly prolongs the overall service life of mechanical equipment.
