Steel bushing

The inner surface can be processed with various types of oil grooves, which improve 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 is based on 45#, 40Cr, 20CrMo, GCr15 and other materials.

Industry Knowledge

Lubrication bushings, also known as self-lubricating bushings, are types of bearings that are designed to operate without the need for additional lubrication. They are made from materials such as sintered bronze, graphite, or plastic, and are often used in applications where frequent maintenance or lubrication is difficult or impossible.
These bushings typically have small pores or indentations on their surfaces that contain lubricating oil or grease. As the bushing moves, the oil or grease is released, which helps to reduce friction and wear on the bearing surface.
Lubrication bushings are commonly used in a wide range of industrial and commercial applications, including automotive, aerospace, construction, and manufacturing. They are often used in applications such as hinges, pivots, and other types of rotating or sliding joints.
Some of the advantages of using lubrication bushings include lower maintenance costs, longer service life, and reduced downtime. Additionally, since they don't require additional lubrication, they are also more environmentally friendly than traditional lubricated bearings.
