An excavator bushing or an excavator bearing is a component of an excavator or other heavy equipment that helps to connect different parts of the machinery together. It is a cylindrical or tapered metal sleeve that is inserted into a hole or bore and acts as a bearing surface to support and guide a shaft or pin.
The bushing is usually made of high-strength steel or bronze and embedded in a special solid lubricant material to reduce friction and wear.

Excavator bushings are commonly used in excavator booms, arms, and buckets, as well as other heavy equipment components such as track linkages and idler wheels. They are designed to withstand high loads and harsh operating conditions and can be easily replaced when worn or damaged.
Proper maintenance and lubrication of excavator bushings are important to ensure optimal performance and prevent premature wear or failure of the equipment.

The excavator bushings are an important part of the machine’s chassis system, supporting the weight of the excavator and helping it to move over the terrain.Oilless bearing acts as a pivot point between the excavator’s track chain and its link components.

They are cylindrical sleeves made of cast bronze bushing embedded in a solid lubricant that is pressed into the bores of the link assembly to create a wear-resistant bearing surface for the rolling of the track chain.

The solid lubricant provides a thin film of lubrication between the two surfaces, helping to reduce friction, wear, and heat generation. As the self-lubricating material wears, the lubrication layer is continually replenished, providing long-lasting, maintenance-free operation.

- Casting Bronze Excavator Bushings

Casting bronze bushings is a manufacturing process focused on producing specific types of bearings made from bronze.
These bushings, also known as bronze bearings or sleeves, are commonly used in various applications due to their excellent wear resistance, low friction, and high load-carrying capacities.

Casting bronze bushings allows for the production of complex shapes and sizes that might be difficult or time-consuming to produce using other methods, such as machining from solid blocks. The final product is a high-quality, durable bronze bearing suitable for various applications in automotive, heavy load equipment, such as Excavators.

- Hardened Steel Bucket Bushings

Excavator bucket pins and bushings are generally used to connect the bucket, hydraulic cylinders, booms and the sticks as well as other places on a heavy equipment machine. The pins slot directly through the bushings, proving a circular motion. If you have any heavy equipment machine or a full fleet, you know how import these components are. The pins and bushings are basically the mechanical linkage that holds everything together, as these components wear at the point where their inner diameters meet, they will need to be replaced.
Usually, with a lack of lubrication, they will wear out and need to be replaced. Internal wear happens with regular usage over time, while external wear is typically caused by the outside elements and difficult working conditions. Worn pins and bushings can cause the buckets to stretch and loosen. This stress cause expensive damage to your machine. Fortunately, SinoBronze produces and sells high quality aftermarket components for all your heavy equipment machines.
