Bucket pin-bushing are made of high carbon or 40Cr steel. In order to extend the life of the bushing and the parts around it. It is normally hardened to between 48 and 52HRC. These bearings are extremely strong and durable, and they are excellent in low speed, high pressure, and pivoting motion applications.
Bucket pin-bushing installed in the excavator arm and bucket joint, can be replaced. The bucket pins on a excavator are used to hold the bucket to the excvator. The bucket bushing plays the role of plain bearing, fixing and positioning. It requires low hardness and wear resistance, the inner hole of the shaft sleeve can achieve high matching accuracy by grinding and scraping, and there must be an oil groove of lubricating oil on the inner wall. Some characteristics of bucket bushings include low rotation speeds with high pressures and plain or grooved sliding layers.On top of all that, bushings are still very affordable and are provided at a very low cost.
