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 gears, spur and helical gears with tooth forms up to 45 degrees, with a 450 mm / 17.75 inch face width and height and up to 12metres / 40 foot long.

HRS utilises specialist dedicated CNC rack cutting machines to ensure highest accuracy up to AGMA class 10 spacing tolerances.

Lead and Power Screws

HRS manufactures all types of screws, using performance guaranteed materials and offer unique solutions to power transmission problems.

All screws are cut from performance guaranteed materials.

All screws are subject to stringent quality controls.

All screws 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.
     

Pinions

HRS supply gear pinions to integrate precisely into our gear rack creating a single integrated component from a single source supply.

HRS can perform customisation of the rack and pinion configuration to any customer application to ensure strict quality control and high system performance.
 

Nuts
