Precision Gear Measurement Equipment

Capstan Atlantic utilizes advanced gear measurement equipment including in all phases of the manufacturing process, they include;

HD4™ High Performance Gear System

The HD4™ material system is a Capstan developed system that when combined with surface densification provides outstanding strength and wear properties for the most demanding applications.

The benefits of the HD4™ process are;

  • Custom designed high performance alloy system
  • Superior core density for fatigue resistance
  • Pore free surface density for contact fatigue resistance
  • Mirror like surface finish for quiet running gears
  • Precise Helix angle
  • Custom Involute profiles for noise reduction
  • Tailored Hardening process to meet aggressive rolling contact fatigue requirements
  • Wrought Steel properties with the economies of Sintered Metal
