Product Operating Principe

1. There is a certain gap between the pin and the pin bushing. As we all know, there is a traditional relative motion between the pin and the pin bushing. The pin and the pin bushing use clearance fit.

2. It is not easy to form an appropriate oil film when the clearance is too small. Direct contact between the parts will ead to more friction, even machine locking.

3. If the clearance is much large, there will be a large impact load. the two situations will reduce the working life of parts.

4. A reasonable design of the clearance is very important for an excavator working device.

5. After numerous tests, we get a better design of pin bushings. New bushing is more durable and has a longer working time in comparison to other factories’ bushings. Happily, our customers can get better pin bushings.
