3.1、Si₃N₄ all ceramic bearings

The Si₃N₄ all ceramic bearing ring and rolling element are made of Si3N4 ceramic material, and the retainer uses polytetrafluoroethylene (PTFF) as the standard configuration,

Used for higher speeds and load capacity;

And suitable for higher ambient temperatures;

At the same time, it can provide precision ceramic bearings for high-speed, high-precision, and rigid spindles, with a maximum manufacturing accuracy of P4 to UP levels.

3.2、Fully loaded ball all ceramic bearings

The fully loaded ball type all ceramic bearing, due to its non cage structure design, can accommodate more ceramic balls than the standard structure bearing, thereby improving its radial load capacity. In addition, it can avoid the limitation of cage material and achieve the corrosion and temperature resistance effect of the ceramic cage type all ceramic bearing.

 3.3、Ceramic cage all ceramic bearings

Ceramic cages have the advantages of wear resistance, high strength, corrosion resistance, and self-lubrication. All ceramic bearings made with ceramic cages can be used in harsh environments such as extremely corrosive, ultra-high and low temperatures, and high vacuum.

 3.4、Hybrid ceramic ball bearing

Silicon nitride balls have the characteristics of low density, high hardness, low friction coefficient, no magnetoelectric insulation, wear resistance, self-lubrication, and good rigidity, making them particularly suitable for rolling elements of high-speed, high-precision, and long-life hybrid ceramic ball bearings (with metal inner and outer rings). Generally, the inner and outer rings are made of bearing steel (GCr15) or stainless steel (ALS1440C, 316304).

6、AlN ceramic components 

AlN ceramics have excellent thermal conductivity and thermal shock resistance, as well as good insulation properties. Due to liquid-phase sintering and the absence of secondary phases at grain boundaries, the crystal structure is very dense and has good resistance to plasma corrosion. Widely used as spare parts for substrates and semiconductor manufacturing equipment

7、SiC ceramic components

Compared with other precision ceramics, it has a smaller reduction in mechanical strength and higher corrosion resistance in high temperature environments (1000 ℃). Due to its strong covalent bonds, it has the highest hardness and excellent corrosion resistance among various precision ceramics, and good sliding performance in liquids. Utilizing these characteristics, it is widely used in mechanical seals, chemical industry, bearings, and other fields.

In addition, it has a high Young's modulus and a small swelling coefficient, making it suitable for high-precision components such as optical components.

Due to its dense sintering, it can be subjected to mirror processing, with a high temperature resistance of over 1400 ℃, heat resistance and impact resistance, excellent chemical stability, high thermal conductivity, and its high-purity SiC are often used as components in semiconductor manufacturing equipment.
