How to choose a ceramic bearings
Ceramic bearing supplier
Ceramic bearings have the characteristics of high temperature resistance, cold resistance, wear resistance, corrosion resistance, anti-magnetic and electrical insulation, oil-free self-lubrication, and high speed. Full ceramic bearings can be used in extremely harsh environments and special working conditions. Ceramic bearings can be widely used in aviation, aerospace, navigation, petroleum, chemical industry, automobile, metallurgy, electricity, textile, pumps, medical equipment, scientific research and national defense and military fields. Ceramic bearings are high-tech products for the application of new materials.The ceramic bearings produced by ARESWIN are zirconium oxide (ZrO2), silicon nitride (SI3N4), and silicon carbide (SIC). The retainer is made of PTFE, PEEK, SUS304 and ceramic retainer materials.
According to the type of use scenario, it can be divided into the following categories:
1. High temperature resistant ceramic bearings:
The material itself has a high temperature resistance of 1200℃ and good self-lubrication. It can be used in high-temperature equipment such as plastic and steel making;
2. Corrosion-resistant ceramic bearings:
The material itself has corrosion resistance and can be used in strong acid, strong alkali, organic salt, seawater and other fields such as: semiconductor equipment, food machinery and equipment, electroplating equipment, chemical equipment, textile machinery, medical machinery, shipbuilding, etc.
3. Anti-magnetic ceramic bearings:
The non-magnetic and does not absorb dust, it can reduce premature peeling and noise of bearings. This type ceramic bearings can be used in demagnetization equipment. Precision instruments and other fields.
4. Electrically insulated ceramic bearings:
Due to its high resistance, it can avoid arc damage to bearings and can be used in various power equipment requiring insulation.
According to different materials, the ceramic bearings produced by ARESWIN can be classified as follows.
1. Zirconia full ceramic bearings
Zirconium oxide ceramic bearings have a series of characteristics such as high temperature resistance, low cold resistance, high pressure resistance, corrosion resistance, acid and alkali resistance, anti-magnetic electrical insulation, oil-free self-lubrication, etc., which are suitable for working in special environments where hybrid ceramic ball bearings and steel bearings cannot adapt.
2. Silicon nitride full ceramic bearings
Silicon nitride full ceramic bearings have all the characteristics of zirconium oxide, and also have their own light specific gravity, good wear resistance, and high hardness. Compared with zirconium oxide ceramic bearings, full ceramic bearings made of silicon nitride are more suitable for high speed and load capacity, and are more resistant to high temperatures. At the same time, they have good high temperature strength, mechanical oxidation resistance, high temperature load capacity and good resistance to strong acid and strong alkali corrosive gases.
3. Full ball full ceramic bearings
The full ball type full ceramic bearing adopts a cage-free structure design. The bearing is designed with a ball addition port on one side to facilitate the loading of more ceramic balls, thereby increasing its load capacity. This design is to avoid the limitation of the cage material and improve the corrosion resistance and temperature resistance of the bearing. This series of bearings is not suitable for higher speeds.
4. Hybrid ceramic bearings
Hybrid ceramic bearings refer to rolling bearings in which the rings and rolling bodies are made of different materials. In most cases, the rings of hybrid ceramic bearings are made of bearing steel, whereas the rolling bodies are made of high-performance ceramics, such as silicon nitride (Si3N4).
