Metal Pulleys versus Nylon Pulleys | Advantages of Nylon | Torque Trans

When deciding on the material for any given pulley, the end application will more often than not dictate which material to use.  The vast majority of pulleys used in manufacturing are made from steel or aluminum, while a smaller percent use cast iron or Nylon. All of these materials have unique benefits.

Yes, there are some limitations to Nylon, but for fractional horsepower, these limitations are not an issue. Our Nylon pulleys are rated for the belts they're designed to match. 

Some benefits of Nylon pulleys include:

  • Molded Nylon Pulleys are more Cost-Effective
  • High-Quality Construction: Nylon 33% glass fill and metal hub combination
  • Noise Reduction: Smooth quiet operation
  • Lighter weight and therefore less inertia
  • Shock Resistance: Absorbs loads without breaking
  • Lubricity: Nylon provides a natural lubricated surface, nonabrasive to belts, and requires less maintenance
  • Chemical Resistant: Can be used in a variety of environmental conditions
  • Longer Life: life expectancy is equal to or greater than aluminum
