Si3n4 Hybrid Ceramic Bearings 7202-2RS P4 Grade CNC Machine Spindle Bearings

 

Bearings Feature

 

6706-2RS 30x37x4 sealed hybrid Si3N4 ceramic ball bearing 30x37x4mm S61706RS that's the inner ring, outer ring, cage and shield all made of stainless steel material, Si3N4 ceramic balls Corrosion-resistant, rustproof and durable.

 

Bearing Application

 

Stainless steel ceramic ball bearings widely used in kitchen appliance, shower bathroom, door and window which near the sea, rowing boat, food machinery, chemical machinery and clearing machine, etc.

 

Ceramic Balls

We are special in making Silicone Nitride Balls (Si3N4 Balls), Zicronia Balls (ZrO2 Balls),Sic Ceramic Balls, Aluminum Oxside Valve (AI203) ceramic balls.

Compared with steel, ceramic materials are noted for their better or particular characters, such as wear-resistance, corrosion resistance, high temperature resistance, electrical insulation (except SiC), non-magnetic, high strength, high rigidity, and low specific gravity. These properties qualify them for replacing steel to make bearings serve in conditions of higher speed, harsh environment and less lube, and decrease wear, noise, vibration and maintenance time of bearings, and eventually increase performance, reliability and life of bearings.
