Application in corrosive or humid environments
For industries with corrosive gases or liquids such as semiconductor equipment, or industries with humid environments such as oxygenators for fisheries, bearings are prone to rusting. Therefore, for these special purposes, we have developed stainless steel bearings with high corrosion resistance.
① Bearing basic No:

Experimental condition
· Salt spray test: GB/T 10125-2021
· Experimental solution: 5%NaCl
· Test time: 1hour;
· Temperature:35℃;
experimental condition
· bearing:608
· Fr=38kgf,Fa=3kgf;
· n=3000rpm;
· T=90℃;
The experimental results indicate that the lifespan of stainless steel bearings is comparable to that of standard bearings
