Precision Gear Racks

Precision gear racks have longer in service lives, smoother performance characteristics and more accurate pitch control than other machining techniques.  HRS can machine in straight, spur and helical tooth forms up to 45 degrees, with a 450mm/17.75 inch face width and height and up to 12 meters/40 ft. long.   HRS utilizes specially dedicated CNC rack cutting machines to ensure the highest accuracy up to AGMA class 10 spacing tolerances.

Lead and Power Screws

HRS manufactures all types of screws, using performance guaranteed materials and offers unique solutions to power transmission problems.  All screws are cut from performance guaranteed materials, are subject to stringent quality controls, and are cut rather than rolled resulting in:

  • Greater accuracy.
  • A greater precision fit with mating nuts.
  • The thread is concentric with major diameter.
  • Superior control of cumulative pitch accuracy.


HRS supplies gear pinions to integrate precisely into our gear rack creating a single integrated component from a single source supply.  
HRS can perform customization of the rack and pinion configuration to any customer application to ensure strict quality control and high system performance.


With a wide range of modern CNC machines and a highly skilled workforce HRS can manufacture virtually any nut configuration to exactly match any screw produced working in Steel, Bronze, Plastic or Exotic alloy.

HRS can manufacture high tolerance and safety critical parts where quality and specification compliance is essential.
