Product Description

High Precision Si3N4 Silicon Nitride ceramic bearing

Unlike other ceramic materials, Silicon nitride (Si3N4) is a material with very high resistance to crack propagation.
Silicon nitride balls are used in processing equipment to improve bearing performance. It is lighter, stiffer, smoother, harder, corrosion resistant, require less lubrication, and have a lower thermal expansion than their steel counterparts which allow the bearing to run at higher speeds and higher operational temperatures with lower torque.
 
Advantage:
High wear resistance
High corrosion resistance
High temperature resistance
Dimensional stability and aging resistance
Excellent sliding properties (tribology)
Biocompatibility (for use in hygiene and the food and beverage industry
