24.3mm high alumina ceramic
99 Porcelain Positioning Pin High Hardness Non-Conductive
The ceramic positioning pin has extremely strong corrosion resistance, and can also be used in strong acid, strong alkali and sea water. At 1100 ℃, the strength and hardness are almost unchanged. Can also be used in non-magnetic and magnetic fields. Electrical insulation. The density is 3.25---3.28g/cm3, light weight, about 60% lighter than the steel ball, which greatly reduces the centrifugal force on the channel when the bearing rotates at high speed and reduces wear. High rigidity, high strength, its hardness is twice as high as bearing steel, and the elastic modulus is about 1/3 higher. The coefficient of linear expansion is 3.2×10-6/K, which is almost 1/4 of the bearing steel, and can withstand the rapid changes in temperature.

1. The ceramic positioning pin is similar to the ordinary welding positioning pin, but it is made of super-hard silicon nitride ceramic material. The special physical and chemical properties of ceramic materials determine certain special properties of silicon nitride positioning pins. For example, high wear resistance, high hardness, non-conductive, non-magnetic, non-stick welding slag and other excellent properties.
2. Below I will briefly introduce the performance of ceramic materials:
High hardness: the hardness of zirconia is second only to diamond
High wear resistance: High hardness and good red hardness determine that the zirconia positioning pin has excellent wear resistance
High cost performance: the service life of zirconia positioning pins is several times that of ordinary positioning pins
Ceramic materials such as zirconia and silicon nitride are wear-resistant at high temperatures, used as mechanical parts, as rotors and stators in engines; hot-pressed piston crowns, reaction sintered burners, spark plugs, cylinder liners and other precision parts; heat-resistant Good shock resistance, used as thermocouple casing, ceramic positioning pin, casting mold, crucible, furnace, burner, heating element fixture, furnace lining, aluminum liquid conduit, valve, etc.; good corrosion resistance, used as ball valve and seal in chemical industry Rings, filters, heat exchanger parts, etc.; good wear resistance, used as bearing balls, rollers, seat rings, high temperature bolts, plunger pumps, sealing materials, etc. in the mechanical industry; used in electronics, military, and nuclear industries Used as circuit substrate, film capacitor, high temperature insulator, radar radome, isolator, etc.
The company can customize all kinds of non-standard special-shaped ceramic positioning pins and special-purpose special-shaped ceramic positioning pins according to the customer's use environment, use requirements and required material properties.
