Silicon nitride grinding discs, impeller blades are widely used in the field of powder grinding and are used as chassis. Because silicon nitride ceramics are very hard, second only to diamonds and other materials, there is almost no loss during thegrinding process, and the impurities brought into the product are also minimal. Although silicon nitride is a ceramic product, it has a good crystal structure, and the silicon nitride spherical product can well retain the crystal structure, so that the stress can be dispersed and the various metal ores can be broken.

Ceramic bearings Si3N4. Bearing cage PTFE. For most applications Si3N4 is the preferred material for ceramic bearings. Silicon nitride bearings are light, very hard and highly wear resistant. High and ultrahigh performance bearings are used in e.g. aerospace technology, metal production industries (high application temperatures), machine manufacturing, chemical industries (chemically aggresive substances), pharmaceutical and medical industries, semiconductor and biotechnology (clean room enviroments which may not be contaminated by lubricants). On request Special version with PEEK ball cage. Without ball cage.

Like oxides and nitrides, Silicon Carbide (SiC) is a very hard-wearing material, again requiring diamond-grinding methods to process once fired. Although not exclusively, carbides are used mainly for applications in which physical wear is a major consideration. They are amongst the hardest materials available.

AMB Ceramic Substrate is a method to realize the bonding of ceramic and metal by reacting a small amount of active elements Ti and Zr in filler metal with ceramics to form a reaction layer which can be wetted by liquid filler metal. Advantage: The combination is achieved by chemical reaction between ceramic and active metal solder paste at high temperature, so its bonding strength is higher and reliability is better. Disadvantage: The reliability of AMB process depends largely on the composition of active filler metal, brazing process, brazing layer structure and many other key factors。 Specification >Metallization thickness: 25 ±10um >Nickel thickness:2~10um; >Pin full strength: 4200kgf/cm2 avg.

Our all-ceramic bearings are characterised by their high corrosion resistance to seawater and various chemicals. They are therefore used, for example, in the chemical industry, in the food and beverage industry, in shipping and in chlorine systems. We can manufacture our full ceramic ball bearings with rings and balls made of zirconium oxide (ZrO2) or silicon nitride (Si3N4), depending on the application. They are available with full balls or with cages made of PEEK or PTFE. The runout accuracies common with precision steel bearings cannot be achieved with all-ceramic bearings, so speed values have to be reduced. Ceramic materials are harder than steel, but also more brittle. Silicon nitride in particular has a low elongation at break and tends to break under tensile stress without prior plastic deformation. We take this into account when selecting the optimum bearing solution for your specific requirements.
