Original assembly part characteristics:
The original factory bushings are made of high-strength wear-resistant materials (such as babbitt alloy, bronze, cast iron, or specially treated steel), and have the following advantages:
Precise dimensional tolerances, perfectly matching the shaft and bearing housing, ensuring the concentricity of rotating components;
Excellent wear resistance and friction reduction performance, capable of withstanding radial loads and temperature changes during the operation of the air compressor;
Good heat conductivity, helping to dissipate the heat generated by friction, and prolonging the service life of the shaft and related components.
Key points for model matching:
The specifications of the bushings are closely related to the model of the air compressor, the diameter of the rotor shaft, and the installation position (such as the main unit, motor, or transmission components). Different series (such as GA, ZR, GHS, etc.) of air compressors correspond to different models of bushings. When purchasing, the following information needs to be provided:
The specific model and factory serial number of the air compressor;
The installation position of the bushing (such as the main unit end, motor end);
The part number of the old bushing (usually marked on the component surface or in the equipment manual).
