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



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.



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.



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.
