Belt Tensioner Plastic Pulley
For machinery tension, the high hot deformation temperature is the first choice. PA66 black nylon material density 1.14 and melting points 253℃. High mechanical strength and hardness high rigidity, it's better for constuction machinery.
The tensile,bending,compressive,impact strength are very high,and the Rockwell hardness is 108-118. So it is used as mechanical accessories, such as gears,pulleys,belt tensioners and lubricating bearings.
