The position of the excavator bucket shaft and bushing within the excavator
The position and functional relationship between the bucket shaft and the bushing of the excavator is as follows:
I. Position and Structure of the Bucket Shaft
Installation location
The bucket shaft is located at the connection point between the end of the excavator's bucket arm (large arm) and the bucket, and is fixed to the bucket ears (ear plates) on both sides of the bucket through pins or bolts, forming the power transmission hub between the bucket and the bucket arm.
For example, in excavators of brands such as XCMG and Sany, the bucket shaft is usually a high-strength alloy steel shaft body that has undergone quenching treatment, with threads at both ends or a shaft shoulder design .
Accessory components
The bucket shaft needs to work in coordination with the bucket ears, pins/bolts. Some models are designed with lubrication holes to allow grease to be injected into the bushing .

Ii. Position and Function of the Bushing
Installation location
The bushing is placed in the shaft hole between the bucket shaft and the bucket ear, in direct contact with the bucket shaft. The material is mostly bronze, self-lubricating steel sleeve or PTFE composite material .
For example, the lugs of models such as Lingong and Caterpillar often use steel bushings with oil grooves to reduce friction .
Maintain the associated component
The bushing depends on the regular maintenance of the oiling nozzle and the lubrication system (such as the grease gun) to prevent sediment from entering .

Iii. Component Synergy Relationship
Power transmission : The bucket bearing is pushed by the hydraulic cylinder, and the bushing protects the bucket shaft through anti-friction characteristics, jointly ensuring the stability of the bucket flipping and digging actions .
Typical fault : The wear of the bushing can cause abnormal noise or loosening of the bucket shaft, and it needs to be replaced in time (such as the steel sleeve of the horse-pulling head) .
Note : The design of bucket shafts and bushings may vary significantly among different brands (such as Komatsu and Volvo). It is recommended to refer to the equipment manual or professional maintenance guide .
