Excavator bushing is one of the consumable parts of excavator,

there are many styles of bushing, so it becomes necessary

to choose the right bushing.

There must be a lubricating oil groove on the inner wall of the bushing.

The lubrication of the bushing is very important.

1.Figure 1 shows the deep oil tank bushing.

2.Figure 2 shows the graphite bushing.

3.Figure 3 shows the point bushing flange bushing of excavator.

If there is no oil tank to add lubricating oil to dry the bucket shaft and bushing,

the bucket shaft and the bucket bushing will soon be damaged or even

broken and deformed due to excessive heat, which will reduce the

impact on the service life of the excavator. Due to the large amount

of excavator working environment Dust and sand will easily enter the

gap between the bucket shaft and the bushing, which will cause abnormal

noise of the excavator bucket and accelerate the wear of the bucket shaft and bushing.

Therefore, it is necessary to add lubricant to the bushing regularly to extend the bucket.

The use time of the shaft and the bushing increases

the working efficiency of the excavator,

It is recommended to scrape the inner hole wall of the shaft sleeve during installation,

so that a small pit can be left for adding lubricating oil. The enhanced lubrication bushing

and shaft sleeve are selected according to different industrial and mining conditions.

The most important conditions are: pressure, speed, pressure-speed product, lubrication status, load properties.
