Boca Bearings offers many different bearing styles that are appropriate for use in both semiconductor equipment and semiconductor manufacturing. Ceramic bearings are capable of accommodating the many challenging conditions present during the stages of semiconductor production; from furnace temperatures that can reach close to 2500F to clean-room 1 air quality.

Ceramic materials commonly used for bearings are Silicon Nitride (Si3N4), Zirconia Oxide (ZrO2), Alumina Oxide (Al2O3) or Silicon Carbide (SiC). Ceramic is non-porous so it is a glass like surface that can be used in clean rooms where traditional lubrications and emissions cannot be present. Ceramic is also non-magnetic, non-corrosive and has an extremely low rate of thermal expansion. As a result ceramic bearings can be used in silicon wafer production where high loads and high temperatures are exhibited during manufacturing.

Deep groove bearings, thrust bearings, angular contact bearings and self-aligning bearings are just some of the styles available in Full Ceramic and Ceramic Hybrid versions. Ceramic Hybrid bearings consist of steel races with ceramic balls. Full Ceramic bearings have ceramic races and ceramic balls. Boca Bearings has one of the largest inventories of ceramic bearings in the world but can also have custom bearings built to the specifications of the customer.

Ceramic Bearings :

  • Non-Magnetic
  • Non-Conductive
  • Non-Corrosive
  • Operates Without Lubrication
  • Ideally Suited For Extreme Temperatures

Full Ceramic Bearings
Full Ceramic Bearings are made entirely of ceramic material and are superior to common steel bearings in many ways. Ceramic is the perfect material for any application seeking to achieve higher RPMs, reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present. Applications such as cryopumps, medical devices, semiconductors, machine tools, turbine flow meters, food processing equipment...Learn More »

Ceramic Hybrid Bearings
Ceramic Hybrid Bearings have Steel races and Ceramic Balls. Ceramic Balls are suitable for applications where high loads, high speeds and extreme temperatures are factors. Long life and the need for minimal lubrication make this material appropriate for extreme applications. Ceramic is non-porous, non-magnetic, non corrosive and lighter than steel. In ball form, ceramic balls are also harder than steel and because ceramic balls are non-porous they are virtually frictionless and capable of spinning faster than steel balls...Learn More »
