4638803 BUSHING For HITACHI ZX890-5A 6WG1

The main function of bushing is to connect pipes of different calibers. ‌ It is usually made of hexagonal bar after cutting and forging. There are many types of thread used, which can play an irreplaceable role in pipeline connection.Bushing also has the characteristics of explosion-proof leak-proof and strong pressure resistance, which can ensure the stability and safety of the connection. According to different materials, bushing can be divided into zinc alloy reducer joints, copper nickel plated core and 304 stainless steel reducer joints and other types.

Bushing (also known as bushing or reducer joint) is mainly used to connect two sections of pipe with different calibers, through the design of internal and external threads to ensure that pipes of different calibers can be closely connected to prevent leakage. It is widely used in municipal engineering, chemical industry, oil refining and other industries.

A bushing is a part used to connect pipes of different diameters or as a bearing. It is usually made of metal or other hard materials, used to reduce friction and wear, has a high load bearing capacity and wear resistance, and protects the connection part from damage. bushing can be divided into many types, including automotive bearing, plain bearing, etc., widely used in automobiles, machine tools, motorcycles and other fields
