Penn Machine manufactures a wide range of resilient and solid wheel and axle solutions. Solid steel forged wheels come in a variety of models including lighter weight, which meet the highest AAR and APTA standards and can be customized for any OEM or aftermarket application. Penn Resilient Wheels feature an elastic layer, comprising rubber blocks or ring elements between the steel tire and the wheel center. This design improves ride quality, reduces noise and vibration and lengthens operating life. The company also manufactures standard and low-floor axles at its U.S. facility with in-house heat-treating to sub-critically quench axles vertically.
