Full and hybrid ceramic ball bearings for high-speed, high-temperature, and corrosive environments. Four types cover wind turbine generators, CNC spindles, semiconductor stages, and aerospace gyroscopes. Precision P0 to P5.
Full ceramic for extreme environments; hybrid for high speed and lubrication-free operation. Both Si₃N₄ and ZrO₂ ring/ball materials available.
Rings and balls in silicon nitride. Best for high-temperature, corrosive, and magnetically sensitive applications. Zero lubrication required — runs dry in vacuum.
Rings and balls in zirconia. Best for highly corrosive media — concentrated acids, alkalis, and seawater. Electrical insulator.
Steel rings with Si₃N₄ balls. Lower cost than full ceramic, higher speed than all-steel. Standard choice for CNC spindles and machine tool spindles.
Steel rings with zirconia balls. Cost-effective hybrid for corrosion resistance and electrical insulation without full ceramic rings.
Ceramic bearings solve four specific problems that steel cannot.
Si₃N₄ balls are 60% lighter than steel — at 100,000+ RPM the reduced centrifugal force dramatically extends bearing life.
Full ceramic bearings run dry in vacuum, clean rooms, and food/pharma where lubricant contamination is unacceptable.
Zirconia bearings operate in concentrated acid, alkali, and seawater where steel corrodes within hours.
Si₃N₄ has zero magnetic permeability — mandatory in MRI equipment and magnetic measurement instruments.
Full Si₃N₄ bearings operate to 800°C continuously — steel requires relubrication above 150°C.
Wind turbine main shaft bearings, CNC spindles, aerospace gyroscopes — we supply all three.
Any application where speed, temperature, corrosion, or magnetism exceeds steel bearing limits.
Full Si₃N₄ main shaft and generator bearings for wind turbines. Lubrication-free, 20-year design life.
Si₃N₄ hybrid spindle bearings for machining centres. 40,000–100,000 RPM.
Full Si₃N₄ for inertial navigation gyroscopes and satellite reaction wheels. Non-magnetic.
ZrO₂ full ceramic for pumps and agitators in aggressive chemical environments.
Full Si₃N₄ for MRI-compatible surgical robots and dental turbines. Non-magnetic, sterilisable.
Si₃N₄ hybrid bearings for fuel cell compressors and battery slurry pumps.
One of our longest-running OEM partners — switched from a European competitor's alumina igniters to our BLK series Si₃N₄ in 2018. Warranty returns dropped 38% in the first 12 months; cold-start failures (sub-zero installs) dropped 32%. Now in year 7 of supply.
