Details                                                                                                                                                      

1.Zirconia all-ceramic bearings have features of magnetoelectric insulation resistance, wear resistance and corrosion resistance, oil-free self-lubrication,

 high temperature resistance and high cold resistance, 

2.It can be used in harsh environments and special working conditions. 

3.Rings and rolling elements are made of Zirconia (ZrO2) ceramic materials, 

4.For material of retainer, polytetrafluoroethylene (PTFE) is standard configuration, generally glass fiber reinforced nylon dragon 66(GRPA66-25), special engineering plastics (PEEK, PI), stainless steel (AISI SUS316, SUS304), brass (Cu), etc. can be also used.

Features                                                                                                                                                   

1. Corrosion resistance: The material itself has corrosion resistance, and can be applied to strong acid other than hydrofluoric acid, strong alkali, inorganic and organic salt, seawater and other fields. It is suitable for working under harsh conditions where is full of corrosive media, such as plating equipment, electronic equipment, chemical machinery, ship manufacturing, medical apparatus and instruments, etc.

2. High temperature resistance: between 180℃ and 260℃, ceramic bearings with retainers will not have expansion due to temperature difference. Working temperature of zirconia ceramic bearing filled with balls is between 300℃ and 800℃, and can be applied to high temperature equipment like furnace kilns, plastic and steel manufacturing devices.

3. Self-lubrication: Ceramic bearings have good self-lubricating property for their small friction coefficient and good surface smoothness, especially silicon nitride material, whose self-lubricating performance is excellent. Therefore, ceramic bearing do not need any grease. Under vacuum environment, problem of lubrication for ordinary bearings can be overcome with application of ceramic bearing.

4. Anti-magnetism: Because there is no magnetism and without dust absorption, so problem of early peeling off and loud noise can be reduced, for which it can be used in fields of demagnetization equipment and instruments.

5. Electrical insulation: due to its high resistance, arc damage to bearings can be avoided, so it can be used for power equipment with insulation requirement.

6. Density of ceramic rolling balls is lower than that of steel and their weight is much lighter, therefore, the centrifugal effect on the outer ring during rotation can be reduced by 40%, thus greatly prolonging the service life.

7. Ceramic is less affected by heat expansion and cold contraction than steel, so with constant clearance, bearing can be allowed to work in environment with severe temperature difference.

8. The elastic modulus of ceramics is higher than that of steel, and it is not easy to deform under stress. Therefore, it is conducive to improving the working speed and achieving higher precision.

1. Q: What are Zirconia Ceramic Ball Bearings?

 A: Zirconia Ceramic Ball Bearings are a type of bearing which uses ceramic balls instead of traditional steel or other metal balls. They provide superior performance and are often used in applications where high temperatures, corrosive environments, extreme speeds, and low noise levels are desired. The ceramic material used allows for much higher heat tolerances and resistances to abrasion than traditional bearing materials.

2.Q: What are the advantages of using zirconia ceramic ball bearings? 

A: Zirconia ceramic ball bearings offer many advantages including higher load capacity, higher speed, greater wear resistance, lower friction, and higher temperature stability. They are also lighter, more durable, and more resistant to corrosion than their steel and stainless steel counterparts. Additionally, they can be used in applications where extreme temperatures are present due to their higher temperature limits.
