Description
Gemstone bearing is mainly used in instruments. The bearing of instrument bears little load, but it needs high rotation precision, good sensitivity and long service life. Gemstone has small friction number, high hardness, corrosion resistance, small coefficient of thermal expansion, high compressive strength performance, can meet the requirements of instrument bearings. The materials used for making gem axes are corundum, agate, glass ceramics, etc. Corundum is the body of alumina, both natural and man-made. Natural corundum has many impurities and uneven texture, so artificial corundum is widely used
