High-precision Corrosion-Resistant Carbide Ball and Seat

The ball seat is a part used in conjunction with the tungsten carbide ball. The function of the ball seat is to provide a platform for support and positioning so that the tungsten carbide ball can rotate or roll freely and maintain stable motion. The ball seat usually has certain grooves or holes to ensure that the tungsten carbide ball can be correctly embedded in it and maintain the fit with other parts.

The paired use of Carbide Ball and Seat can provide a lower coefficient of friction, higher sealing performance and longer service life. They are widely used in a variety of mechanical equipment and industrial fields, such as automotive, aerospace, petrochemical and so on.

1. Carbide Balls have good corrosion resistance and can be used for a long time in harsh environments and are not easily affected by corrosion and oxidation.
2. The hardness of Tungsten Carbide Balls can reach HRA90 or above, which can maintain stable performance under high load and high speed.
3. Tungsten carbide balls have very high machining precision and dimensional stability, which can meet the precision requirements of customers.
4. Tungsten Carbide Balls have good wear resistance and can maintain a long service life under high friction and high load conditions.


Tungsten carbide balls are usually used to manufacture high temperature, high pressure and high-speed friction vice, such as piston rings and valve balls of automobile engines. Tungsten carbide balls can also be used to manufacture seals, such as valve sealing balls, pump sealing balls, etc. to provide good sealing performance.
