MASS TRANSIT – AXLES

Axles That Keep You Rolling

We manufacture regular and low-floor axles to exact tolerances in solid, hollow, inboard and outboard designs. Our axles meet Association of American Railroads (AAR) and International Union of Railways (UIC) standards, as required, and can be sub-critically quenched in our heat treatment facility.

Sub-Critical Quenching

After we rough-machine axles, we:

  • Place them in a vertical position in an electric furnace for sub-critical quenching (axles typically remain in the furnace for one hour per inch of diameter based on the size of the axle’s largest fit)
  • Remove the axles from the furnace & quench them in water (axles remain in the water bath until they cool to an ambient temperature of about 70°F)
  • Finish-machine the axles to customer specifications

We use AAR-approved methods for non-destructive testing (NDT) and perform dimensional checks to ensure quality when the manufacturing process is complete.

To complement our production capabilities, we also re-condition axles and supply flexible couplings, replacement gears and rubber components for gearboxes and related products. We also offer a full range of hubs.
