Urethane for the Wood Industry

Urethane Used for Woodworking Applications

wood working urethane drive wheels
The Woodworking industry and machines have long had wheels, rollers and custom parts made from Urethane. Acrotech Inc. has noticed that over time the OEM materials either did not last or are of poor quality. We have developed a line of woodworking specific products that are direct replacement for existing machinery. With the use of K•Prene® at the core of these demanding applications you are able to get more life out of your machinery and processes. Increase your productivity with Acrotech and K•Prene® woodworking products.

 

Available Woodworking Urethane Products

wood working urethane parts

Urethane Drive Wheels

  • drive-wheelsStocked in 80A Durometer – other durometer’s are available upon request.
  • Designed with 3 or 6 bolt mounting holes to fit various re-usable hubs on woodworking Moulders, Planers and Re-Saws like: Weining, Mattison, Baker, SCMI, Bridgewood, Extrema, Wadkin, Diehl and more.
  • Tires/Wheels can be used in other applications to drive various other materials beyond wood without marking or damaging.
  • Non-marking: Won’t mark pre-surfaced or pre-finished stock as does steel or rubber wheels.
  • Eliminates slippage: Excellent traction out performing steel wheels and they provide feed control for higher output.
  • Gone are Raised Grain Problems: The high-friction of the tire/wheel provides more traction with less pressure, eliminating the major cause of raised grain. This will increase the overall quality of the product
  • Economical to use: Tires/Wheel are easy and quick to change.

When ordering, be sure to specify the durometer desired.
