Product Description

Full Ceramic Bearings

Full Ceramic Bearings are designed for applications operating in extreme special environments where conventional bearings are not suitable for. An antifriction 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).

Hybrid Bearings

GIL advanced ceramics hybrid bearings have steel inner and outer rings and rolling elements made from Silicon Nitride.Therefore hybrid bearing have many excellent performance such as heat resistance, extended life, light weight, lower thermal expansion and electrically non-conductive.

Ceramic Ball Bearings

They are advantageous in having a longer service life, lower friction resistance, higher seizure resistance, higher corrosion resistance, higher rigidity, higher temperature resistance ( up to 800C) lightweight (40% of bearing steel), non magnetic, and insulated.

Material Selection
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
