1、 Cast iron, cast steel.
Traditional bearing seats are made of cast iron and cast steel, with a long history of use and mature technology.
2、 Rolled steel.
The bearing seat made of precision fused rolled steel has higher strength and stability than traditional cast iron and cast steel bearing seats, and is widely used in steel casting, mining machinery, and polluted environments.
3、 Ductile iron.
Due to its fine texture, ductile iron material is stronger and stronger, resulting in a lighter and thinner design of the ductile iron bearing seat, which is about 40% lighter than traditional bearing seats. However, its strength has been increased by 30%, making a contribution to the rationalization of mechanical design such as miniaturization and lightweight.
4、 Stainless steel.
Stainless steel bearing pedestals are more corrosion-resistant than the previous items (which is obvious). Generally, stainless steel bearing pedestals are pre sealed with thermosetting grease, which is less prone to leakage and has a longer lifespan. Even in high temperature and high-speed environments, they will continue to provide stable lubrication. In addition, due to the smooth casting surface of stainless steel, foreign objects are not easily attached, making it cleaner.
5、 Plastic (thermoplastic polyester resin).
Compared to traditional bearing pedestals, they are lighter and more corrosion-resistant, and have a wide range of applications due to their ability to rust. Due to the chemical inertness of plastic itself, it is a standard bearing seat in the food, beverage, and pharmaceutical industries.
6、 Others.
In addition to the five types of bearing seats mentioned above, materials such as silver, manganese, tungsten, and zinc are used in some extreme application scenarios, such as ultra-high temperature, ultra-magnetic environment, and ultra-high speed.
