1.Products imformation

The bucket bushing is anti-cracking because we do surface treatment after hermal refining 

to guarantee the inside hardness and outside cracking-resistance. Our 40Cr 45# high-

strength bushing is designed for excavator and bulldozer and the bushing is manufactured through strict procedures. 

1) Forging. The bushing is placed in the workshop after being forged.

2) Subsequent processing. The bushing is processed according to your requirements.

3) Rough grinding. After being grinded by the lathe, both ends of the bushing become flat and it is semi-finished.

4) Drilling. Before drilling, an oil slot will be dug.

5) Heat treatment. In the metalworking workshop, the quality of the bushing will be firmly strengthened under nearly 1000°C heat treatment.

6) Tempering. After being tempered, the hardness can reach 48-52 HRC.

7) Fine grinding. We grind the inner side and then the outer side. In this sequence, we will not damage the product.
