Cone Crusher Parts Eccentric Bushing

Product Overview

The eccentric bushing is the core component of the crusher, especially the cone crusher. It has the dual functions of transmitting power and buffering impact. The eccentric movement of the head is realized through the eccentric structure to complete the crushing operation of the ore.

The main functions of the eccentric bushing of the crusher include supporting and guiding the movement of the main shaft to ensure that the machine can perform crushing operations smoothly and effectively. Specifically, the eccentric bushing is installed on the main shaft. As the shaft rotates, the bushing and the body below have different degrees of friction. The force generated by this friction pushes the material in the crushing chamber to achieve precise crushing.

In addition, the eccentric bushing also has the following functions:

1. Reduce friction and wear: The eccentric bushing is usually made of high-strength cast copper material with good wear resistance and corrosion resistance. This material can still maintain a long service life in a long-term high-load working environment. 

2. Reduce equipment temperature: Copper has excellent thermal conductivity, which helps to reduce the heat generated by friction and avoid overheating of equipment. 

3. Shock absorption effect: The eccentric bushing can effectively reduce shock, reduce the vibration of the equipment during operation, and protect other key components. These characteristics make the eccentric bushing play a vital role in the crusher, ensuring the stable operation and efficient operation of the equipment.
