About the bearing
Made of precious stones and other hard materials made of sliding bearings. Gemstone bearings are mainly used in instrumentation. Instrumentation bearing load is very small, but requires high precision rotation, good sensitivity, long service life. Gem has a small coefficient of friction, high hardness, corrosion resistance, thermal expansion coefficient is small, high compressive strength performance, to meet the requirements of instrumentation bearings. Production of precious stones bearing materials are corundum, agate, glass and so on. Corundum is the crystal of alumina, which is natural and man-made. Natural corundum more impurities, uneven texture, so the most widely used corundum Agate is a natural mineral, but often contains impurities, need to remove the mixed impurity fringe part of the material utilization is low. Glass-ceramic is a glassy crystalline material. Glass bearings made of glass-ceramic technology is simple, low cost, has a wide range of applications. But it is carrying capacity is low, the manufacturing is not easy to ensure the exact size, it is not suitable for manufacturing high precision bearings. Gemstone bearings in the form of the structure is mainly divided into through-hole gemstone bearings, bearing gem bearing and groove-shaped gemstone bearings.
