Zirconia full ceramic bearing

All ceramic bearings have the characteristics of anti-magnetic and electrical insulation, wear resistance and corrosion resistance, oil-free self-lubrication, high temperature and high temperature resistance, etc., which can be used in extremely harsh environments and special working conditions. Ferrules and rolling elements are made of zirconia (ZrO2) ceramic material, and the holder uses polytetrafluoroethylene (PTFE) as a standard configuration. Generally, glass fiber reinforced nylon 66 (RPA66-25) and special engineering plastics (PEEK, PI), stainless steel (AISISUS316), brass (Cu), etc.

Silicon nitride full ceramic bearings

Silicon nitride all-ceramic bearing rings and rolling elements are made of silicon nitride (Si3N4) ceramic material. The holder uses polytetrafluoroethylene (PTFE) as a standard configuration. Generally, RPA66-25, PEEK, PI, and phenolic clips can also be used. Cloth bakelite tube, etc. Compared with ZrO2 materials, all ceramic bearings made of SiN4 are suitable for higher speed and load capacity, as well as higher ambient temperature. At the same time, it can provide precision ceramic bearings for high-speed, high-precision and high-rigidity spindles, with the highest manufacturing accuracy of P4 to UP.

Full ceramic ball bearing

Full-ball full ceramic bearings have a ball gap on one side. Because of the cageless design, more ceramic balls can be installed than bearings with standard structure, which improves its load capacity. In addition, it can also avoid the limitation of the cage material. , Can achieve the ceramic cage type full ceramic bearing corrosion resistance and temperature resistance. This series of bearings is not suitable for higher speeds. When installing, pay attention to install the notched surface on the end that does not bear axial load.

Ceramic cage full ceramic bearing

Ceramic cages have the advantages of wear resistance, high strength, corrosion resistance and self-lubrication. All ceramic bearings made of ceramic cages can be used in harsh environments such as extreme corrosion, ultra high and low temperature and high vacuum. Common ceramic materials are ZrO2, Si3N4 or SiC.

Hybrid ceramic ball bearings

Ceramic balls, especially silicon nitride balls, have the characteristics of low density, high hardness, low coefficient of friction, wear resistance, self-lubrication and good rigidity. They are especially suitable for high-speed, high-precision and long-life rolling ceramic ball bearings For metal). Generally, the inner and outer rings are made of bearing steel (GCr15) or stainless steel (AISI440C), and ceramic balls can be made of ZrO2, Si3N4, or SiC materials.
