Fenner Drives - Powermax Pulleys & Idlers - Round Belt Idlers

  • The PowerMax Advantage:
  • Fenner Drives is the industry leader in molded composite solutions for industrial power transmission and material handling applications. PowerMax Composite products are used where dependability counts most.
  • High-strength glass reinforced composite idlers and pulleys are available in a wide range of sizes for flat, round and V-belts.
  • Fenner Drives' composite products are a lightweight, corrosion resistant alternative to steel, aluminum and cast iron.
  • Designed for use with round belts, ropes or cables. The deep uninterrupted groove provides continuous support and eliminates any binding or wedging problems found with steel or cast iron pulleys. Small series pulleys are ideal for tight-fit applications.
