Silicon nitride bearings are belong to ceramic bearing

Silicon nitride bearings are belong to ceramic bearing,silicon nitride bearings ceramic bearing ring and rolling body are made of silicon nitride (Si3N4) ceramic material.Rpa66-25, PEEK, PI, phenolic laminated bakelite pipe and so on can also be used.SiN4 all-ceramic bearings are suitable for higher speeds and load capacities as well as for higher ambient temperatures than ZrO2 materials.At the same time, it can provide precision ceramic bearing for high speed, high precision and high rigidity spindle, with the highest manufacturing accuracy UP to P4 to UP level.
Ceramic ball especially silicon nitride bearings ball has the characteristics of low density, high hardness, low friction coefficient, wear resistance, self-lubrication and good rigidity, especially suitable for high speed, high precision and long life hybrid ceramic ball bearing rolling body (inner and outer ring is metal).

Generally, the inner and outer rings are made of bearing steel (GCr15) or stainless steel (AISI440C), and the ceramic balls can be made of ZrO2, Si3N4, or SiC.
Ceramic bearing ball helps the injection molding machine turn green, silicon nitride bearing ball loads up to 1,800 kN, axial speed up to 160 m/min, acceleration using certain parts of Cronidur 30 steel helps resist corrosion.silicon nitride bearings makes high performance bearing balls.They're a little bit smoother than a ball of steel and they reduce rolling friction and they have a density of a, a little bit less than a ball of steel,silicon nitride bearings have maximum RPM.They are also non-conductive, which means that they do not cause arc damage to the bearing surface by rotating electrical machines in a highly excited state around the field and minimize current-related heat accumulation.

Jinan Maolei Bearing Co.,Ltd. is silicon nitride bearings manufacturer for many years,our silicon nitride bearings are very good.
