Full Ceramic Bearings

Zirconia Full Ceramic Bearing introduction:

Full ceramic bearings are made of zirconium oxide ceramic material.Ceramic bearings are consist of ceramic balls, ceramic rings and retainers.The ferrule and rolling elements are made of zirconia (ZrO2) ceramic material, and the retainer uses polytetrafluoroethylene (PTFF) as the standard configuration. Generally, glass fiber reinforced nylon 66 (GRPA66-25), special engineering plastics (PEEK, PI), stainless steel (ALSI SUS316, SUS304), brass (CU), etc.Zirconia ceramic material has resistant to electromagnetic insulation,wear-resistant,corrosion-resistant,self-lubricating,high hardness and resistant to high temperatures etc. feature.It is the ideal material of ceramic bearings.

Full ceramic bearings filled with balls:

The full-ball full ceramic bearing has a ball-filling gap on one side. Because of the cageless structure design, more ceramic balls can be loaded than the standard structure bearing, thereby improving its radial load capacity. In addition, it can also avoid the cage material. It can achieve the corrosion resistance and temperature resistance effect of ceramic cage type full ceramic bearing. This series of bearings are not suitable for higher speeds. When installing, pay attention to installing the notched surface on the end that does not bear the axial load. Because the inner and outer rings of the bearing have ball-filling gaps, it is not suitable for applications with large axial loads.

Ceramic cage full ceramic bearing:

Ceramic cages have the advantages of wear resistance, high strength, corrosion resistance and self-lubricating. Full ceramic bearings made of ceramic cages can be used in harsh environments such as extremely strong corrosion, ultra-high and low temperature and high vacuum. Commonly used cage ceramics The material is ZrO2.

Features of Full Ceramic Bearings:

1,Corrosion resistance:The ceramic material itself has corrosion resistance feature and can be applied to strong acid,alkali,inorganic salt,organic salt and seawater other than hydrofluoric acid etc. fields.Such as electroplating equipment,electronic equipment,chemical machinery,shipbuilding,medical equipment etc.

2,High temperature resistance:The ceramic bearing with retainer can be working on temperature between 180° C -260° C ,and does not cause expansion due to temperature differences.Fully loaded ball zirconia ceramic bearing can be used in furnaces,melting steel and other high temperature equipment.

3,Self-lubrication:Due to the small friction coefficient of ceramic bearings,Its surface is very smooth.So it has very good self-lubricating properties,especially the silicon nitride material lubrication performance is better.Therefore,ceramic bearings donot need to add any grease.

4,Non-magnetic:Ceramic bearing does not absorb dust.It can reduce the risk of bearing early peeling,noise and so on.Can be used in demagnetication equipment,precision instruments and other fields.

5,Insulation:Ceramic bearing has high resistance,so can avoid arc damage bearings,It can be used in a variety of electrical equipment.
