What is the spider bushing material?
The material for spider bushing is Gray iron: EN-GJL-350.
The raw material is high strength cast iron, with good mechanical property, as well as a good ability to absorb the energy of crusher’s vibration. It’s a great help to make the rotation of the main shaft running steady, which can continuously stable the output of your crusher. The heat treatment of tempering is applied to release the internal stress. It’s a great help to prevent the part’s dimension change in the daily operation of your crusher. It obviously can prolong the life of your crusher. The final machining is carried by the CNC machine to ensure each dimension tolerance, which helps to make your assembly easy and fast, to improve the efficiency of your production and maintenance.
Why the spider bushing is important?
The Spider bushing has an hourglass figure and as such it has a very tight clearance. Once the spider bushing no longer supports the main shaft, the bottom of the main shaft exerts a large amount of force on inner eccentric bushing. If the spider bushing is not maintained, the following problems will happen:
- Burnt inner and outer eccentric bushing;
- Sized main shaft;
- Damaged step bearings;
- Damaged locating bar;
- Damaged main shaft and shaft sleeve.
In one word, not maintaining this item will cause serious damage to the internal mechanical components of your cone crusher.
