Excavator harden steel bushings
Product Introduction
JNM GROUP 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.
Our steel hardened bushings are subjected to case hardening and tempering treatment; these treatments best enhance the characteristics of the bushings and allow them to be used in environments where particular resistance to wear and seizure is required: earth moving and agricultural machines.
All sizes bushing bucket bushing available:40mm 50mm 60mm 65mm 80mm 90mm 100mm 120mm
Material: 42CrMo 45# 40Cr 20CrMo GCr15
Our steel sleeves are manufactured using advanced production technology and premium materials to ensure consistent quality and performance. Whether it's an excavator, loader or other heavy machinery, our steel bushings are designed to meet the highest standards of durability and reliability.

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.
