Excavator boom arm bucket pins and bushings
Product Introduction
Excavator boom bushing, or boom excavator bushing, is equivalent to excavator bushing. These are the bushings that are found in the arm, or boom, of the excavator. They serve a very important function, as they support extremely heavy loads and ensure smooth and sturdy movement of the excavator's arm.

Product Features
Bushings are widely used in various industrial applications such as in excavators, cranes, bearing housings and other equipment. Excavator bucket bushings are important components in excavators used to reduce friction, protect mechanical components and improve work efficiency. Excavator bucket bushings are installed on the joints and connecting parts of the excavator, such as turntable bearings, bucket rods and booms and other key parts, to ensure the smooth operation and extended service life of these parts.
There are many types of bushings, and they can be classified according to different criteria, such as material, application, etc. Here are some common types of steel bushings:
Metal Bushings: Can be made from various metals or alloys such as steel or stainless steel, brass to enhance their performance.
Sleeve and Flange Bushings: Sleeve bushings are basic cylindrical components while flange bushings are designed with flanges to handle the combined loads.
Bronze Bushings: Bronze bushings are general-purpose bushings with excellent load-carrying and wear protection capabilities.
Self-lubricating bushings: Self-lubricating through a uniform indentation pattern on the bushing surface (acting as a grease reservoir), ideal for low- or maintenance-free operation. Such as blind hole/oil storage bushing, mesh bushing.
