Bearing-grade ceramic balls for precision bearings, ball screws, pumps, valves, and check valves. Grade G3 to G60, diameter 0.4mm to 100mm. Si₃N₄ (lighter, harder) and ZrO₂ (denser, tougher) from stock.
Si₃N₄ ceramic balls for precision bearings, ball screws, and high-speed spindles. 60% lighter than steel, hardness 78 HRC, non-magnetic, lubrication-free capable.
ZrO₂ ceramic balls for corrosive-media pumps, check valves, and food/pharmaceutical equipment. Higher density than Si₃N₄ — ideal for valve seats and grinding applications.
ISO 3290 grade number = max allowable deviation in micrometres. Lower grade = tighter tolerance = higher precision. Choose based on your bearing accuracy class (P0–P5) and operating speed.
For high-precision angular contact bearings, spindle bearings, and gyroscope bearings. Max deviation ≤0.08µm (G3). Aerospace and semiconductor spindle applications.
Standard for P4 and P2 bearing accuracy class. CNC spindle bearings, dental turbines, and precision instrument bearings.
General-purpose bearings, ball screws, and pump check valves. P0–P6 accuracy class. Cost-effective for high-volume industrial applications.
For valve seats, flow metering, and applications where chemical or thermal resistance matters more than roundness tolerance.
Any bearing, pump, or valve that fails in steel due to speed, temperature, corrosion, or magnetism.
Si₃N₄ balls for angular contact, deep groove, and hybrid ceramic bearings. 3× longer life vs steel at high speed.
Ceramic balls for CNC and semiconductor lithography ball screws. Zero stick-slip, lubrication-free.
ZrO₂ balls for check valves and pump seats in corrosive chemical and food-process environments.
Si₃N₄ balls for dental turbines and surgical instrument bearings. Biocompatible, autoclavable.
G3 Si₃N₄ balls for gyroscope and navigation system bearings. Zero magnetic signature.
ZrO₂ balls for wet and dry milling of ceramic slurries, pigments, and battery materials.
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.
