Benefits of Polyurethane Wheels

Our ExtraGlide 70D polyurethane wheels offer numerous benefits for your operations. These include:

  • Noise reduction: Polyurethane wheels roll quietly and offer significant noise reduction compared to steel and iron options. This helps reduce workplace noise and improves employee comfort.
  • Load-bearing capacity: Polyurethane wheels offer considerable load-bearing capacities and won’t easily deform or delaminate.
  • Coefficient of friction: Polyurethane wheels have significant traction and won’t slide like metal wheels. This ensures carts and equipment roll smoothly along any surface.
  • Floor protection: Heavy loads can damage the flooring. Polyurethane wheels protect concrete, tile, and other surfaces from damage. The design of the wheels means that prolonged use won’t result in ruts and divets.
  • Corrosion resistance: Polyurethane wheels are designed for reliable operation within harsh environments. Oil, grease, salt, blood, or harsh chemicals won’t degrade the material or reduce performance.
