High-speed precision ceramic bearings with an inner diameter of 10-60mm can be divided into three precision grades: P4, P4A and P2. The limit revolution can reach 80000 RPM. The rotating accuracy and service life of bearings are comparable to the world's top brand physical bearings. Si3N4 Silicon Nitride Ceramic Ball: Small starting torque, long service life, high rigidity, high operating accuracy, insensitive to temperature, good self-lubrication, good insulation, good corrosion resistance, good ceramic material, itself has extremely high acid and alkali resistance, strong salt spray resistance, with special alloy steel processing bearing has perfect corrosion resistance and high temperature resistance. Cage using nylon (TYN), phenol resin (TR)PEEK and other engineering plastic material products, self-lubrication performance is good, small friction coefficient, low bearing heat when high-speed rotation, widely used in high-speed machine tool spindle bearing. The size of 70 series ceramic bearing contains all sizes of products from 7001C HQ1/P4(inner diameter:12mm outer diameter:28mm) to 7018C HQ1/P4(inner diameter:90mm outer diameter:140mm)
Feature of Ceramic ball: 1, corrosion resistance, strong acid and alkali, seawater can also be used. 2, light weight, 1/4 lighter than the general material bearing, its density is 3.20g / cm3. 3, high rigidity, high strength, its hardness is twice as high as the bearing class, and the elastic modulus is about 1/3. 4, high-speed rotation, rotating body (the weight of the ball is light, the centrifugal is small when rotating. Silicon nitride ceramic ball is a kind of precision ceramic sintered at high temperature in non-oxidizing atmosphere. It has high strength, high wear resistance, high temperature resistance, corrosion resistance, acid and alkali resistance. It can be used in seawater for a long time, and has good properties of insulation. At 800 C, the strength and hardness are almost unchanged, and its density is 3.20g/cm3, which is almost 1/3 of bearing steel. Small weight and small centrifugal force in rotation can achieve high speed operation. It is also self-lubricating, it can be used in the environment without high pollution of lubricating medium. It is the preferred material for ceramic bearings and mixed ceramic ball bearings.

Fasteners are the general term of the class of mechanical parts used in fastening two or more parts (or components) into a whole. It is widely used in energy, electronics, electrical appliances, machinery, chemical, metallurgy, mold, hydraulic and other industries, at the same time, in various kinds of machinery, equipment, vehicles, ships, railway, bridge, construction, structure, tools, instruments, chemical, instruments and supplies, you can see all kinds of fasteners, is the most widely used mechanical foundation parts. It is characterized by a wide variety of variety specifications, different performance uses, and a very high degree of standardization, series, and generalization. Therefore, a class of fasteners that already have national standards is called standard fasteners, or simply standard ones.
A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. In most applications, one race is stationary and the other is attached to the rotating assembly (e.g., a hub or shaft). As one of the bearing races rotates it causes the balls to rotate as well. Because the balls are rolling they have a much lower coefficient of friction than if two flat surfaces were sliding against each other. Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area between the balls and races. However, they can tolerate some misalignment of the inner and outer races.
