The plastic bearing unit is unique in light weight, easy to install and maintenance-free, and it has the shock absorption and shock resistance performance of common cast iron bearing housing or stamped bearing seats. With the continuous development of new bearing seat 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 bearing unit generally use PBT material.

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.

PVDF, PTFE (Teflon), PPS (polyphenylene sulfide), PEEK (polyetheretherketone), PI (polyetherimide), etc. have all proven to be ideal materials for making high-temperature plastic bearings, where PI can be used at a long-term temperature of 290 It can be used under the environment of ℃, and the short-term temperature resistance can reach 350 ℃. It is the best type of high temperature performance among all known engineering plastics.

HDPE, PP, UPE materials have been proven to be used in relatively weak acid-base cross environments (30% Cucl2 solution and 30% NaoH solution test OK), so they are suitable for most acids / bases / salts / solvent / oil / gas and Seawater corrodes the environment. It has the properties of oil-free self-lubrication and anti-magnetic electrical insulation of general plastic bearings, but its mechanical strength is low and it is easy to deform. Therefore, this type of acid-proof and alkali-resistant plastic bearings is not suitable for large loads and high speeds. Disadvantages of alkaline plastic bearings. In comparison, the use of UPE material has better strength, low friction characteristics and low temperature application characteristics (minimum to -150 ℃). Generally, the inner and outer ring materials are HDPE, PP or UPE, and the cage materials are HDPE, PP or UPE, ball is glass ball, stainless steel ball or ceramic ball. In this way, the comprehensive performance of acid and alkali bearing will be greatly improved.
