Engineering Plastic PU Bushing

Engineering Plastic PU Bushing

PB3M is the substitute of and parallels in performance with abroad iglidur M250. The self-lubricating plain bearings made of PB3 are distinguished by their impact strength, vibration damping and wear resistance. Their application in vibration damping is necessary, for example, in fitness and packaging machines. Because they can also absorb dust, they are also suitable for agricultural machinery and garden tools.
