Petroleum machinery tungsten carbide bushing

 Petroleum machinery tungsten carbide bushing
 

The tungsten carbide bushing is used to position or protect the shaft on the rotating shaft to prevent the shaft from being worn. At the same time, the hardness of the grinding shaft is low, and the shaft without the quenching and tempering can be used, thereby reducing the processing difficulty of the related parts.

  The advantages of our petroleum machinery tungsten carbide bushing

1.       Using high-quality cemented carbide raw materials, using advanced molding technology such as cold pressing and vacuum sintering technology, we can produce hard alloy non-standard shaped products with various complex shapes, with stable performance and reliable quality.

2.       Unique production control and detection technology, the internal stress of the production of shaped products is controlled, effectively avoiding the cracking phenomenon when the product is cut online, away from defects such as pores and cracks.

3.       Non-destructive ultrasonic flaw detection, no blisters, no porosity, high density of materials; high strength, impact resistance, high wear resistance and long service life.

4.       Dimensions and specifications: Produced according to customer samples or drawings.

5.       Carbide sleeve grades are: YG6, YG8, YG11, YG15, YG20, YG6X, YG10X, YG8C, YL10.2, etc.
