Product Operating Principe

It has a certain gap between the pin shaft and the shaft sleeve having a traditional relative motion. What’s more, the clearance fit is adopted between the pin shaft and the shaft sleeve. If the clearance is too small, it is difficult to form a stable oil film. Direct contact between the pin shaft and the bushing causes heat, greater friction, and machine locking. If the clearance is too large, it will lead to a large impact load. All of the above will affect the service life of shaft sleeve and pin shaft. Therefore, the reasonable design of the clearance between the pin shaft and the shaft sleeve is very important for the use of excavator working device. After numerous tests, we have a better design of shaft sleeve and pin shaft. This kind of product is more durable and has a longer lifespan compared with other factories’ product. So, our customers san get better shaft sleeves and pin shaft.
