Product Details                                                                                                                                                                     

0.750kg 79×79×57mm steel Bucket Bushing is used widely. And it belongs to excavator quick-wear spare parts.

With many methods for machining, there is no air holes in the bushing.

Wider cross-type lubricating oil channel.

Large reserves.

longer service time.

higher cost performance.

With the process of quenching and tempering treatment, bushings become black and looks like a round chocolate.

Compared with chocolates, bushings are also smooth.

Bucket bushings are easy to install and won't hurt our hands.

Product Parameters

Product Processes

There are 16 processes for making a shaft sleeve:

cutting stock—forging— quenching and tempering treatment—rough turning—code printer —oil line processing—hardening— temper —coarse and fine grinding for inner bore—excircle grinding—deburring—inspection—pickling—surface conditioning—Phosphating—packing and storage

Product Operating Principe

1.Gap     

There is a certain gap between the pin shaft and the shaft sleeve having a traditional relative motion. The clearance fit is adopted between the pin shaft and the shaft sleeve.

2.Situations       

It is difficult to form a stable oil film when the clearance is too small. Direct contact between the two parts leads to greater friction, even machine locking.  When the clearance is too large, it will create a large impact load. These situations will reduce the service life of  these parts.

3.Design       

According to the operating principe, a reasonable design of the clearance has a great impact on the use of excavator working.With thousands of tests, we gain a better design of pin bushings. New bushing tough enough to take abrasion will suffice. So, we gain a longer lifespan bushings.
