Product Description
Professional Manufacturing Of Top-Level Excavator Bucket Parts Steel Hardened Bushings
Product Description
Hardened steel bushings are mechanical components used in various applications to provide a bearing surface or support for rotating or sliding shafts, rods, or other components. They are typically cylindrical in shape and made from hardened steel, which undergoes a heat treatment process to increase its strength and durability.
The primary purpose of hardened steel bushings is to reduce friction and wear between two moving parts. They are commonly used in machinery, automotive applications, industrial equipment, and other mechanical systems where there is a need for precise and reliable movement.
The hardness of the steel used in hardened steel bushings is typically achieved through heat treatment processes such as quenching and tempering. This increases the material's resistance to deformation, wear, and fatigue, allowing it to withstand heavy loads and prolonged use.
Hardened steel bushings can be designed to fit into a housing or be pressed into a bore, providing a low-friction surface for a shaft or rod to rotate or slide within. They are often used in conjunction with other components like bearings or shafts to create a complete assembly that allows for smooth and controlled movement.
SN-H Steel Bushing
SN-H Steel Bushing
The inner surface of SN-H steel bushing bearing is processed with various types of oil grooves, which improves the surface hardness and wear resistance after heat treatment. It is suitable for heavy-duty joint parts of construction machinery such as excavators, rotary drilling rigs, large loaders, wall grab and so on.
The steel bushing bearing of our company is based on 45#, 40Cr, 20CrMo, GCr15 and other materials. From raw materials to finished products, each process is strictly controlled to ensure the product quality. It produces bushing with high wear resistance, high surface hardness and strong internal toughness.

Product Advantages
The inner wall of the bushing is evenly distributed with blind holes with conical cross-section.
The lubricating oil wedge is formed naturally during the grinding process of the inner hole of the bushing
The oil storage capacity of oil pocket is large, which is 3~5 times of that of ordinary oil tank and can be free from maintenance for a long time.
The oil pockets are evenly distributed on the inner wall, and the center distance of the oil pockets in the circumferential direction is fixed. No matter how large the bushing is, it only needs a small rotation angle to fill the inner surface of the bushing with the oil cloth, without lubrication dead area.
The oil pockets evenly distributed in the inner holes do not damage the bearing capacity of the inner wall of the bushing and prolong the service life of the bushing.
Material: 20CrMnTi, 20CrMo and other low carbon alloy steels Surface treatment: Molybdenum disulfide spraying
SN-X Mesh steel bushing
Due to the combination of double surface treatment and special surface morphology, the mesh bushing has excellent wear resistance and seizure resistance. This cross hatch morphology provides a grease reservoir in the load area and can remove abrasive particles. They are suitable for working under harsh working conditions: High pressure, wear, impact and corrosion. Mesh sleeves are alternatives without cross-hatches. They provide excellent performance under high static loads (low dynamic pressures) and small oscillations (wear resistance and seizure resistance...)
