Features :

  • Positive grip of belt teeth with pulley tooth eliminate slippage and speed variation
  • Belt teeth engage with pulley axial groove in a smooth rolling motion, resulting in minimum friction and reduced noise and wear
  • There is no chordal rise and fall of pitch line as with roller chain no belt creeper or slippage and hence no chatter of vibration.
  • No friction, no elongation, no lack of tension, its unusually high mechanical efficiency and reduced bearing load and it increases bearing life.
  • Drive permits smaller pulley size, short centre distance and narrower belt width, as well as horse power-to-weight ratio high, reduces space required and also weight of drive.
  • Drive provides wide load capacity from sub fractional horsepower to 600HP.
  • Drive ranges is from 10RPM to 10,000 RPM, between two spindles and multi-spindle drive system.
  • In absence of metal to metal (metallic pulley and rubber/P.U belt) contact eliminates the need for lubrication systems, oil retaining device and their nuisance, cost, weight and possibility of product contamination.
  • Suitable for all type of power transmission, indexing, positioning, conveying systems multi-shaft drive because of high accuracy drive
  • Reversing drive is possible with double sided tooth belts, known as twin-powder and belt, also. Running serpentine drives.
