The use temperature is between 100C and 800C without expansion due to temperature difference. 3. The rings and rolling elements of ceramic bearings are made of all ceramic materials, including zirconia (ZrO2) and silicon nitride (Si3N4) silicon carbide (Sic).
The ferrule and rolling elements are made of zirconia (ZrO2) ceramic material, and the retainer uses polytetrafluoroethylene (PTFE) as the standard configuration. dvantage First, because ceramics are almost not afraid of corrosion, ceramic rolling bearings are suitable for operation under harsh conditions full of corrosive media. The wave of large-scale application of ceramic bearings has surged!
Classification of ceramic bearings (1) High-speed bearing: It has the advantages of cold resistance, small force elasticity, high pressure resistance, poor thermal conductivity, light weight, and small friction coefficient. Ceramic bearing zirconia All ceramic bearings have the characteristics of anti-magnetic and electrical insulation, wear-resistance and corrosion resistance, oil-free self-lubrication, high temperature resistance and high cold resistance, and can be used in extremely harsh environments and special working conditions.
Due to the cageless structure design, more ceramic balls can be loaded than the standard structure bearing, thereby improving its load capacity and avoiding the limitation of cage material , China roller bearings manufacturers It can achieve the corrosion resistance and temperature resistance of ceramic cage type full ceramic bearings. With the continuous progress of processing technology and the increasing level of craftsmanship, the cost of ceramic bearings has been declining., and can withstand composite loads. For metal). The retainer is made of polytetrafluoroethylene, nylon 66, polyetherimide, zirconia, silicon nitride, stainless steel or special aviation aluminum, thereby expanding the application range of ceramic bearings
