High-precision 440C Stainless Steel Thin-section Bearing SD080AR0

440C stainless steel is the mainstream base material for Super Precision Stainless Steel Bearings, achieving a comprehensive balance between hardness and corrosion resistance through a high carbon and high chromium ratio. Through proper heat treatment processes, materials can achieve the hardness required for bearings, effectively resisting wear caused by rolling contact and extending the service life of bearings. Compared to 304 type austenitic stainless steel, 440C has a significant advantage in hardness after hardening, making it more suitable for bearing raceways that bear contact stress. It can withstand moisture and weak corrosive media, reducing the problem of precision loss caused by rust. After hardening, the brittleness of the material increases, so it should be protected from severe impact conditions. It is widely used in the manufacturing of stainless steel bearings for automated equipment, small servo mechanisms, and other applications.

Our product range includes high-precision hybrid ceramic ball bearings, ultra-thin section bearings, servo motor bearings, high-precision stainless steel bearings, vacuum pump bearings, magnetic levitation bearings, thin-section crossed roller bearings, reactor bearings, all-ceramic bearings, food and beverage bearings, new energy vehicle bearings, excavator bearings, and construction machinery bearings. We also provide non-standard customized bearings to meet the requirements of various working conditions.
