NU204 Ceramic Roller Bearing Of SSiC Races And Balls+PEEK Cage
Description of NU204 (SSiC races and balls+Peek cage):
1. SSiC races and balls: Are made of highly purified, sub-micron silicon carbide material and are sintered by pressureless sintering technology.
2. Peek cage: Peek has many material advantages, such like high temperature resistance 260 degrees, excellent mechanical properties, good self-lubrication, chemical corrosion resistance, flame retardant, peel resistance, wear resistance, not strong nitric acid, concentrated sulfuric acid, radiation resistance, super mechanical properties can be used in high-end machinery, nuclear engineering and aviation science and technology.
