customized cemented tungsten carbide sleeve bushings
Tungsten Carbide bushings have the characters of high wear
resistance, high corrosion resistance and good compressive
properties.It's widely used in petrochemical industries and other
industries which call for high properties of the mechanical parts.
Tungsten carbide parts holds incredible potential for the oil and
gas industry and mining- where leading installations are already
profiting from its Wear-resistant, corrosion-resistant and high
hardness.

Grade as following :
YG6,YG6X,YG8,YG8.2,YG8L,YG15,YG20,YG20C,YG20D etc are the
traditional material,suitable for the normal tungsten carbide
roller.
1. Tungsten carbide bushing 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.
In the field of valve applications, the tungsten carbide bushing is
in the bonnet and is the corrosion-resistant materials for sealing.
3.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.
