Double metal self-lubricating bushing/Oilless bearings
Product Introduction
JINYO is a pins and bushings manufacturer and supplier. We have specialized in the production of heavy machinery parts for many years. Our products cover most of the markets in Europe, America, Middle East and Africa with strong price advantages.
Self-lubricating bushings , also known as oilless bearings or dry bearings, are bearings that do not require external lubrication. They are commonly used in excavators because they can withstand heavy loads, high temperatures, and harsh environments without the need for regular maintenance or lubrication. JINYO is a professional excavator bushing factory that specializes in producing high-quality cast bronze bushings and self-lubricating bearings.
JINYO accepts orders for any type of special material excavator bushings or custom size oilless bearings, subject to minimum quantity requirements.

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.
Composite bearings: These bearings are made of steel back sintered bronze with POM or PTFE coating, to provide high strength and self-lubrication.
Solid lubricant bearings: Solid lubricant bearings: These bearings are made of a solid lubricant material, such as graphite, that is embedded in a metal matrix. The solid lubricant material provides self-lubrication.
The first major consideration for anyone in the excavator market will be the size, digging, and lifting capacity required for the project. Whether it is a large machine or a 1-4 tonne mini excavator. Choosing the right excavator bushings is very important, depending on the nature of the work to be completed.
