Product Description

Specifications

Our ceramic ball bearings are manufactured from Si3N4 Silicone Nitride when a high heat
resistance and low friction are needed. The lightweight of this hard ceramic reduces skidding and wear under acceleration and high speeds.

Silicon nitride balls are also extremely resistant to chemicals and other corrosive elements, and their moderate rate of thermal conductivity plus low coefficient of thermal expansion reduces cooling costs.

Strengths
* Retains strength and hardness up to 1800 °F
* Excellent resistance to corrosion and chemicals
* Weighs 60% less than steel
* Longer life than steel
* Generates less friction
* Low coefficient of thermal expansion
* Low thermal conductivity which reduces need for system cooling
* Good shock resistance
* High elasticity
* High fracture toughness
* Requires minimal lubrication
* Non-porous
* Non-magnetic
