Full Ceramic Bearings are designed for applications operating in extreme special environments where conventional bearings are not suitable for. An anti-friction ball bearing constructed entirely of ceramic material. Inner/outer races and balls are made of either Silicon Nitride (Si3N4), Zirconium Oxide (ZrO2) or Silicon carbide (SiC). Configurations retainers can be made of composite materials such as PEEK, PTFE or full complement versions without retainers are available for your heavily radial loaded applications.
Silicon Nitride (Si3N4) – Excellent fracture toughness at high temperatures and thermal shock resistance
Zirconia oxide (ZrO2) – Extremely strong and tough
Silicon Carbide (SiC) – Lightweight material with high corrosion resistance and excellent heat resistance
Alumina Oxide (Al2O3) – The most widely used ceramic materials.
Self aligning Full ceramic ball bearings have two rows of balls and a common sphered raceway in the outer ring. The bearings are insensitive to angular misalignment of the shaft relative to the housing.
