| Hybrid ball bearings (Inner and outer roller way is metal, rolling element is Si3N4) Hybrid bearings have advantages relative to steel bearings |
| 1.High speed Hybrid bearings can reach 3,500,000 DN in the condition of oil-mist lubrication, and can reach 1,200,000DN in the condition of grease lubrication, this owes to the greatly reduction of relative slip, wear extent and heat productivity. |
| 2.Long service life The service life of hybrid bearings is 3 to 5 times of that of steel bearings in suitable working conditions. |
| 3.Self lubricating Even in the condition of bad lubricating or no lubrication, hybrid bearings can ensure the bearings work regularly owe to its self lubricating. |
| 4.Corrosion resistant Hybrid bearings have good corrosion resistance, and can work regularly in the condition of corrosion. |
| 5.High rigidness The elastic ration of ceramics is 1.5 times of that of bearing steel, this highly increases the rigidity of bearing. |
| 6.Low friction moment Ceramics materials have low friction force, even in the condition of boundary lubrication, the surfaces are still very smooth, so its friction force is low and the rotation friction moment is low, also. |
| 7.Wear resistant The microhardness of ceramics can reach HV1700 kg/mm2, this highly increases the wear-resistance of bearings. |
| 8.Light in weight The weight of ceramics is lower 60% than that of steel, this decreases highly the centrifugal force and the whole bearing’s weight. |
9.Special performance |

| Hybrid construction ceramic ball bearing |
| Ceramic ball especially Si3N4 have the following performance as low density, high strength, low friction coefficient, electrical and magnetism resistance, wear resistance, well rigidity, lubrication and maintenance free when working, it?ˉs the best choice for rollers (inner ring and outer ring are made by metal) of the hybrid construction ceramic ball bearing which are used in high-speed, high accuracy and long life environments. Normally, GCr15 or （AISI440C,316 304) makes inner ring and outer ring; The ceramic ball can adopt ZrO2, Si3N4 or Sic. |
