POLYMER AND NYLON IDLERS
Product comprehensive performance:
Light weight, easy installation, maintenance-free, stable operation, low noise, long life, no damage to the belt, with excellent self-lubrication and chemical corrosion resistance, anti-aging, starting, running torque is small, can effectively save energy.
Our company adopts bearings for Harbin or Xinkaite bearings single-side sealed roller special deep ball large clearance nylon reholder bearings, special bearings filled with lubricating oil. Bearing seat is made of excellent engineering plastic reinforced nylon, and has a convex green bearing outer ring, and has a honeycomb sound absorption hole, bearing seat and bearing assembly by special machinery high pressure into the assembly. The sealing is made of vacuum ring sealed or vortex labyrinth, which is made of dust proof, water proof and sound insulation. When assembled, the interior must be assembled according to the procedures. The plastic pipe body is made of nylon polymer material outer surface processing ring ventilation groove, color is: white, and has the characteristics of heat resistance, wear resistance, no cracking, no deformation, its hardness :85 shorea, tensile strength of more than 25MPa, elongation at break: more than 209%, bending strength: more than 45MPa, wear resistance: below 180mm. (8bx 15° x 100rpm test conditions). The pipe body is dustproof and rainproof. When the shaft rotates, there will be no stuck phenomenon and unbalanced state. The shaft and bearing tolerance fit is h5(loose fit), the bearing seat and bearing tolerance fit is N7(tight fit), the shaft is carbon steel Q235 steel light two-precision cold-drawn round steel rod. The end of the tube body is rounded to avoid cutting the belt. Retainer cover, circlip, the use of professional phosphating blackening anti-rust treatment. The friction coefficient of the tube body should be less than 0.02 and not attenuated for two years. Normal operation since the beginning of the month more than 30, 000 hours.
