Product Overview


Special-shaped ceramic positioning pins have extremely strong corrosion resistance, and can also be used in strong acids, strong alkalis, and seawater. At 1100 ℃, the strength and hardness are almost unchanged. Can also be used in non-magnetic and magnetic fields.


Uses of shaped ceramic positioning pins: automobiles, clutches, engines, universal joints, axles, motorcycles, crankshafts, connecting rods, loaders, excavators, power tools, pneumatic tools, construction machinery, etc.
Classification of special-shaped ceramic positioning pins: fixed positioning pins, replaceable positioning pins, tapered positioning pins, trimmed positioning pins, standard diamond shaped positioning pins.
Ceramic positioning pin material: zirconia and alumina, silicon nitride ceramic material.


We can customize various types of non-standard special-shaped ceramic positioning pins and special-purpose special-shaped ceramic positioning pins according to customers' use environment, use requirements and required material properties.

Product advantages
  1. High hardness: the hardness of zirconia is second only to diamond
  2. High wear resistance: High hardness and good red hardness determine that the zirconia positioning pin has excellent wear resistance
  3. High cost performance: the service life of zirconia positioning pins is several times that of ordinary positioning pins


Ceramic positioning pins can be applied to accessories for special purpose parts of high temperature resistance, corrosion resistance, wear resistance, and high voltage resistance used in industries such as electronics, machinery, chemical industry, metallurgy, textiles, and power.
After the positioning pin is worn, it will produce a blocking effect when loading and unloading, causing the positioning hole of the part to be hooked. In order to ensure the accuracy of the relative position between the two parts after the certificate is installed, cylindrical pins or tapered pins are often used for positioning, so the requirements for the pins and pin holes are high. In order to facilitate the processing of pin holes and pins, as far as possible, the pin holes are made as through holes as much as possible.
