Kubota Excavator Pin on Bucket to Quick Attach
What material are excavator pin and bushings?
The pins and bushings are made from 4140 material and heat treated to a 65 Rockwell hardness for extended wear life.
Bucket pin and bucket bushing (sliding bearing) hinged piece is composed of excavators, loaders, bulldozers, cranes, concrete pump truck arm posture, overhead working truck and other construction machinery operation device commonly used articulated device, qualified articulated fitting clearance should be reasonable, the fit clearance can be stored, grease to ensure pipe shaft and shaft sleeve to reduce wear and resistance in relative motion.The reasonable fit clearance of the hinged parts can leave a certain space for the thermal expansion generated when the pin shaft moves relative to the shaft sleeve, so as to prevent sintering.If the hinge gap is super poor, it will cause the pin shaft and shaft sleeve to fit loose, produce vibration, impact and eccentric wear, resulting in aggravation of wear or shaft fracture, and even lead to major equipment and personal accidents.Over-poor hinge clearance will also cause deviation and shaking of the operation device of construction machinery, which will lead to the decrease of its operating accuracy and efficiency.Therefore, keeping reasonable hinge clearance is an important link to improve the reliability of construction machinery.
