The plastic bearing unit is unique in light weight, corrosion resistance, easy installation and maintenance-free. At the same time, it has the shock absorption and shock resistance performance of common cast iron bearing seats or stamped bearing seats. With the continuous development of new bearing housing materials, more and more widely used in engineering. According to different situations, plastic outer spherical bearings can be made of different materials such as POM, HDPE, PP, UPE, PTFE, etc. Relative to plastic outer spherical bearings, PBT is generally used.
The most typical varieties of fluoroplastics, PTFE and PVDF have the best corrosion resistance. Among them, PTFE is the best corrosion resistance of all known engineering plastics. It can be used in all concentrated acid and alkali situations, including HF. And fuming sulfuric acid and nitric acid (more than 98%), etc., and have good high temperature performance. PTFE has been proven to be used at high temperature of 180 ℃, PVDF can also be used at 150 ℃, but PTEF material has extremely low mechanical strength and poor dimensional stability. The temperature deformation is large. Compared with PVDF, it has better comprehensive performance. Generally, the inner and outer ring materials are PTFE or PVDF, the cage material is PTFE or PVDF, and the balls are generally glass balls or ceramic balls.
Characteristic of Plastic Bearing Unit:
1.Excellent chemical resistance, able to withstand all strong acids (including aqua regia) except molten alkali metals, fluorinated media and sodium hydroxide above 300C, as well as strong oxidants, reducing agents and various organic The role of solvents
2. Excellent heat resistance, its melting temperature is 324 °C, decomposition temperature is 415°C, maximum use temperature is 250°C, embrittlement temperature is -190°C, and thermal deformation temperature (under 0.46MPa) is 120°C.
3. It has the smallest surface tension in solid materials and does not adhere to any substances.
4. Low friction performance, friction coefficient is the lowest among known solid materials
5. Resistance to aging
6. Good flexibility
