The traditional bearing seater are made of cast iron and cast steel, the use of a long time, the process is mature.
Rolled steel precision fusion manufactured from the bearing seater, than the traditional cast iron, cast steel bearing seater higher strength, but also more stable, in steel casting, mining machinery, pollution environment is widely used.
Ductile iron material because of its fine texture, and thus stronger, more solid, so the ductile iron bearing seater design is lighter and thinner, about 40% lighter than the traditional bearing seater, but the strength is increased by 30%, for the miniaturization of machinery, lightweight and other rationalization of the design has contributed.
Stainless steel bearing seater than the first few more corrosion-resistant (this is obvious), the general stainless steel bearing seater will be pre-sealed into the thermosetting grease, grease is not easy to leak, longer life, even at high temperatures, high-speed environment, will continue to provide stable lubrication. In addition, because the stainless steel casting surface is smooth, foreign objects are not easy to adhere to, so more clean.
More lightweight than the traditional bearing housing, but also more resistant to corrosion, because it will not rust, so the use is very wide. Because of the chemical inertness of the plastic itself, so it is the standard bearing housing for the food and beverage, pharmaceutical industry.
In addition to the above five bearing housing, in some extreme application scenarios, such as ultra-high temperature, ultra-magnetic environment, ultra-high speed and other applications, such as silver, manganese, tungsten, zinc and other materials will be used.
