Of all the components in an excavator, bucket bushings probably suffer the most – constant contact with the ground, sand and abrasive materials, with every digging and dumping cycle. Hydraulic Seals Store offers durable bucket bushings, alongside hydraulic seals and the rest of our range of bushings.
With every digging and dumping cycle, the bucket hinge takes a direct impact – hence the faster wear compared to other bushings on the machine and the need for extra attention during maintenance, especially on machines used intensively for excavation work in tough terrain.
Sand and abrasive particles that enter the joint accelerate wear on the bushing and pin. A correctly sized bushing that is regularly greased leaves less space for contaminants to enter, which extends the service life of the assembly and reduces the frequency of necessary maintenance. In very dirty working conditions, it is also important to periodically check the condition of the seals and contact surfaces.
The diameter of the bucket pin, the hardness of the material (usually heat-treated steel) and compatibility with the excavator model must all be correct – otherwise you risk excessive play and rapid wear. Pin guards provide additional protection for this joint, further reducing the ingress of debris. It is also worth checking the length of the bushing, as well as the manufacturer’s recommended tolerances, as even a small difference can affect how the joint operates. When replacing the bushing, it is advisable to inspect the surface of the pin as well, to ensure that the new bushing does not fit onto a part that is already damaged.
We stock abrasion-resistant bucket bushings, complete with full technical specifications to help you quickly identify the correct size. Delivery is fast, and prices remain competitive for preventative maintenance of your machinery, regardless of how intensively it is used on site.
