Tungsten Carbide Bushing

  1. Tungsten carbide bushing are mainly used for stamping and stretching. It has the characteristics of wear resistance and impact resistance.
  2. It is the supporting parts used in the mechanical parts, in order to achieve sealing, wear protection and other functions.
  3. In the field of valve applications, the tungsten carbide bushing is in the bonnet and is the corrosion-resistant materials for sealing.
  4. In the field of bearing application, the carbide bushings are used to reduce wear between the bearing and the shaft seat, and to avoid the increase of clearance between shaft and hole.

More Detailed Introduction Of Tungsten Carbide Bush

Tungsten is known for its high melting point and durability. It’s also resistant to corrosion, which is ideal for industrial and manufacturing use. Likewise, bushings made from carbide offer an outstanding shelf life. That means you’ll spend less time switching out worn-down bushings, and more time getting the job done.

The main function of the cemented carbide bush which is a kind of tungsten carbide part, is that it can be used as the protection part of the equipment. In the process of service, tungsten carbide bushing can effectively reduce the wear between the bearing and the equipment.

In terms of stamping dies, carbide bush is widely used. Because of its wear resistance and good surface finish,  it does not need to be replaced frequently, which can achieve higher utilization of equipment.
