Product Overview


Product Description

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.

* 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

* Risk of toxic off-gassing when heated to decomposition
* Subject to attack by acids and may generate flammable hydrogen gas under highly acidic conditions

Our ceramic balls are used in bearings for spindle motors of machine tools, turbochargers, and dental drills that rotate at high speeds. Ceramic balls are also used as check balls in metering pumps for fluid control in water treatment and food applications.
Our ceramic balls are indispensable for creating the future for environmentally friendly applications such as wind power generators, electric vehicles, and semiconductor manufacturing equipment that supports 5G technology.
By using silicon nitride balls on the wheel hub
(bottom bracket) of your bicycle, you can reduce friction, reduce weight and extend bearing life.
Silicon nitride ball bearings are used in
semi-conductor manufacturing equipment due to the high speeds and low lubrication conditions.
As compared to using steel balls, the use of silicon nitride balls in the bearings has shown to increase bearing life by 50% or
