Product Description
Jewel Bearings are precision miniature components typically made of synthetic sapphire and ruby because of their superior hardness and ability to accept a high polish.
Synthetic sapphire exhibits exceptional performance of high hardness, high strength, scratch resistance, corrosion resistance, and small coefficient of friction. Jewel Bearings out of sapphire are ideal material for instruments, meters, control devices, precision mechanisms where low friction, long life, and dimensional accuracy are important. Due to its high temperature resistance and chemical durability, sapphire jewel bearings are particularly useful for the applications in Petrochemical, Process Control and Medical Instrumentation. Sapphire Jewel bearings present highly consistent static friction and low kinetic friction. sapphire-on-steel has a static coefficient of friction of 0.10~0.15. Jewel bearing surfaces maintain their smoothness even after decades of use, which means jewel bearings have very low friction variability.
we offer a wide range of high precision jewel bearings for industrial and military applications. Typical types: Cup Jewel Bearing, Vee Jewel and Ring Jewel Bearing.
