The 6805 is an ultra-thin-walled precision deep groove ball bearing made of 440C stainless steel, 440C stainless steel also named 9Cr18, its hardness is HRC58-62. It features high hardness, high wear resistance, resistance to moisture/weak acid corrosion, high-speed stability, and high dimensional accuracy, making it suitable for applications requiring confined installation space, damp and clean environments, high-speed precision, and mild corrosion.
6805 stainless steel bearing configuration:
Materials: Inner and outer rings are both 440C stainless steel
Retainer: PA66 reinforced nylon retainer (PEEK optional depending on operating conditions)
Rolling elements: Silicon nitride ceramic balls
Seals: Special Fluororubber seals
Grade: P5/P4 grade
Applications of 6805 440C stainless steel bearings are as follows:
