Bearing materials
The material of bearing can be divided into ceramic bearing, plastic bearing and so on. performance comparison of ordinary bearing steel GCr15, stainless steel AISI440(9Cr18), silicon nitride (Si3N4) and Zirconia (ZrO2).
Ceramic bearing, as an important mechanical base part, takes the lead in the world of new materials for its high temperature resistance and super strength due to its incomparable performance.In recent ten years, it has been widely used in various fields of national economy and people's livelihood.
Plastic bearings can be generally divided into plastic rolling bearings and plastic sliding bearings;The working principle of the plastic rolling bearing and the plastic sliding bearing can be distinguished by the name.
The sliding friction occurs when the plastic sliding bearing works.The size of the rolling friction mainly depends on the manufacturing precision;The friction of plastic sliding bearing is mainly determined by the material of bearing sliding surface.
DSR bearing has always used high quality steel, you are welcome to consult order.
