The description of tungsten carbide ball
Tungsten carbide balls are also called cemented carbide balls,
bearing balls or just simply carbide balls. High hardness and
dimensional stability make tungsten carbide balls the preferred
choice for precision hydraulic valves, high-load bearings, inertial
navigation systems, ball screws, linear bearings in sideways,
gauging and checking instruments, and meters. We can manufacture
and supply tungsten carbide balls of different diameters, different
tungsten carbide grades or chemical compositions, different surface
conditions, both in sintered blank and fine grinding
The Application of tungsten carbide ball
The applications of tungsten carbide balls are extremely broad,
such as: precise bearing balls, instruments, meters, pen, spraying
machines, pumps, machinery parts, valve seals, brake pump,
extruding hole, oil, hydroelectric acid lab, hardness measuring
instrument, fishing gear, with heavy, ornamented, finished, and
some other high-end industry!
The characteristics of tungsten carbide ball
Tungsten carbide balls are ideal for applications. It hardness must
be accompanied by high resistance to wear and impact. They are
well-suited to elevated temperatures, corrosion, humidity,
abrasion, and poor lubrication conditions.
The working process of tungsten carbide ball
Heat treating: This high temperature process hardens the ball.
Grinding or polishing: The ball is then ground to the approximate
diameter of the finished tungsten carbide balls. This polishing
process the ball to the exact size required.
