Cemented Tungsten Carbide Bushes For Bearing High Production Drilling
Customized Cemented Carbide Bush Tungsten Carbide Sleeves for Bearing
Carbide bushings are appropriate for long-run high-production drilling applications. These higher-cost drill bushings are made of tungsten carbide material for extreme wear resistance. PC bushings are the carbide version of our popular P bushings, which are permanently pressed into the plate, usually flush with the top surface. HC bushings are the carbide version of our popular H bushings, which are also permanently pressed into the jig plate and have a sturdy head to resist heavy axial loads. The head can be left exposed, or recessed by counterboring the installation hole. SFC bushings are the carbide version of our popular SF bushings, which are replaceable bushings generally used with a liner bushing and lockscrew. Other bushing types including Directed-Coolant Bushings, Gun-Drill Bushings, and special-to- print bushings are also available in carbide. All carbide bushings are manufactured to drawing.
Product Description:
customized cemented tungsten carbide sleeve bushing
Tungsten Carbide sleeve 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 sealing rings or parts.

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.
