1.Product Feature
PB7 is the substitute of and parallels in performance with abroad iglidur W300 . The most common plastic bearing material. It is suitablefor the applications with working temperature not higher than 80℃.Itis the prefereable material with good wear resistanceand economic efficient for a new designation.
· Continuous working temperature :-40 ℃~ 80 ℃,
· Very common, suitable for most of average and low load
· Maintenance-free dry operation,
· Light wear against different shaft materials,
· Low friction.
