Ceramic Ball Bearing The hybrid ceramic ball bearing developed by Shanghai Lily Bearing Manufacturing Co., Ltd. features bearing rings made of bearing steel (Gcr15) or stainless steel (9cr18). The ceramic ball bearing is mainly made of silicon nitride (Si3N4),rconia (ZrO2) or alumina (Al2O3),among which Si3N4 is of excellent overall erformance and has become the preferred material for ceramic ball bearing.The density of Si3N4 ceramic is 3.20g/cm3, much lower than that of bearing steel (7.85g/cm3). For this reason, the ceramic rolling element can effectively restrain the centrifugal force generated by high-speed rotation and reduce the load of rolling element. Meanwhile, it can also reduce the rotational slide between the rolling element and the raceway surface and thus prevent surface damage. Therefore, ceramic ball bearing is the best choice for high-speed rotation application, such as high-speed motor spindle bearing, machine spindle bearing, dental drill bearing, high-speed wheelhead bearing, instrument bearing and hard drive bearing. It can also be used in civilian products like roller skate, aeromodelling and electric toy. The introductions of the ball bearingsSingle-row deep groove ball bearings are the most common type of rolling bearing, having a wide range of suitable applications. The raceway grooves on both inner and outer rings have circular arcs of slightly larger radius than that of the balls. In addition to radial loads, axial loads can be applied in either direction. Because of their low torque, they offer high speed operation with low power loss. Miniature and instrument bearings are made with very high levels of precision, therefore these are generally used in applications where accurate rotational performance and low torque is necessary, and load capacity is a secondary issueIt acts as a professional exporter of china made quality bearings,the products covering precise ball bearings,needle roller bearings,angular contact ball bearings,pillow block,linear motion ball bearings 5 series.It's business focus on small and middle size bearings as these china bearing's quality has been well enhanced upon the rapid progress of producing technics and quality control.
