Due to the structural design of the zero holder, the fully ceramic ball bearing (Si3N4 or ZrO2) contains spaces for ball filling, which allows more ceramic balls than bearings of standard structure and hence enhances loading capacity. In addition, the limitation of holder material can be prevented, so the effect of corrosion and temperature resistance for ceramic holder-type of fully ceramic bearing can be achieved. The disadvantage is that the bearings of this series are not suitable for higher speed of rotation since there is no maintainer.

features:

1. Temperature resistance: Expansion due to temperature variance is not generated under temperature of 100?-600?, thus the product is applicable for furnace & kiln, plastic and steel manufacturing equipments.
2. Corrosion resistance: The material is corrosion resistant, thus the product is applicable in fields of strong acid, strong base, inorganic, organic salt and sea water (e.g. plating equipment, electronic equipment, chemical engineering machinery, ship manufacturing and medical facility).
3. Magnetic proof: Due to its magnetic-free property that does not attract dust, premature detachment and loud bearing noise can be reduced, which makes the product applicable in fields of demagnetizing equipment and precision instrument.
4. Electrical insulation: Due to the high resistance, bearing damage from arcing can be avoided, which makes the product applicable in various electrical equipment, precision instrument or electrical equipment that request for insulation.
5. Vacuum: Due to the unique oil-free and self-lubricating characteristics of ceramic materials, the fully ceramic ball bearing can overcome of problem of impossible lubrication for common bearings in an ultra vacuum environment.

The cold static process can produce ceramic products of high strength structure and high quality. We mainly supply the ceramic products that use ZrO2 and Si3N4 as main material. We can manufacture most of the structural products and our plant has passed international certifications such as ISO 9001:2000, OQS and IQNET.
