XinZhou BEARING is a specialized manufacturer of Hybrid Ceramic Bearing. Full Complement ceramic bearings,Ceramic Balls.
Hybrid Ceramic Bearing:
Ceramic bearings offer a significant performance improvement from those made from traditional steel. Our ceramic bearings are manufactured from silicon nitride (Si3N4), an exceptionally hard non-metallic material rated for speeds to 2 million dN, offering a wide selection of benefits.
Hybrid Bearings have steel rings and ceramic balls. Si3N4 Ball is the most popular for the balls as it has only 40 percent of the density of bearing steel but is much harder giving greater wear resistance. Zirconia is heavier with 75 percent of the density of steel so is less suitable for hybrid bearings..
FULL CERAMIC BEARINGS
Full Ceramic Bearings are made entirely of ceramic material and are superior to common steel bearings in many ways. Ceramic is the perfect material for any application seeking to achieve higher RPM’s, reduce overall weight or for extremely harsh environments where high temperatures and corrosive substances are present. Applications such as cryopumps, medical devices, semiconductors, machine tools, turbine flow meters, food processing equipment, robotics and optics. Ceramic materials commonly used for bearings are Silicon Nitride (Si3N4), Zirconia Oxide (ZrO2), or Silicon Carbide (SiC.)
We are special in making Silicone Nitride Balls (Si3N4 Balls,Zicronia Balls (ZrO2 Balls),Sic Ceramic Balls , Aluminum Oxside Valve (AI203) ceramic balls.
Compared with steel, ceramic materials are noted for their better or particular characters, such as wear-resistance, corrosion resistance, high temperature resistance, electrical insulation (except SiC), non-magnetic, high strength, high rigidity, and low specific gravity. These properties qualify them for replacing steel to make bearings serve in conditions of higher speed, harsh environment and less lube, and decrease wear, noise, vibration and maintenance time of bearings, and eventually increase performance, reliability and life of bearings.
Deep Groove Ball Bearings are the most common type bearings . It is mainly used for pure radial load to bear, and also to support
radial load and axial load. When the only pure radial load to bear, the contact angle is zero. And the performance with angular contact
bearings can bear large axial load. When the deep groove ball bearings with a larger radial clearance, Deep groove ball bearing friction
coefficient is small, speed is also high, especially in large high speed axial load condition, the deep groove ball bearings are more advantages
than . thrust angular contact ball bearings.
Deep groove ball bearings are used for high speed or high speed running, the advantages mainly for the durability, without regular maintenance;
and low coefficient of friction, high limiting speed, simple structure, low cost, easy to achieve high manufacturing precision. Size range and diverse forms,
can be used in precision instruments, low noise motors, automobiles, motorcycles and general machinery industries .there is no doubt that the Deep Groove
Ball Bearings are the most widely used bearings in machinery industry.
In addition, the deep groove ball bearings installed in the shaft after the bearing axial clearance within the shell , it can limit the axis or axial displacement in both directions .
Therefore be made in the two-way axial positioning, and aligning with a certain ability.
