Steel Lead Screw Nuts

We stock a large range of steel nuts that are ready for next day delivery which include cylindrical, square and hexagonal nuts.

  • They are used as a fixing nut or for manual movements where the load is not important.
  • The use of steel/steel is not suitable for applications involving a motorised motion.

Stainless, Plastic and Nylon Lead Screw Nuts

  • Stainless cylindrical nuts are stocked in various sizes and are suited to environments where corrosive chemicals are used.
  • Flanged plastic nuts are available for applications that have a high usage. The extra length of these lead screw nuts greatly reduces wear and they are also self-lubricating.
  • Cylindrical Nylon Nuts for the manual or powered control applications sold by Automotion Components. They reduce noise level on machines and can be used without lubrication.

Precision Lead Screws

Stainless Steel 416 and Aluminium Precision Lead Screws are higher accuracy than our commercial lead screws and are provided in a greater range of "leads" (amount travelled per complete turn)

  • 416 series stainless steel has the highest machinability of any stainless steel. It is a martensitic grade and is magnetic.
  • They are available with round, rectangular, or anti-backlash nuts

Ball Screws

A ball screw is a mechanical linear actuator that translates rotational motion to linear motion with little friction. Due to them being made to close tolerances they are suitable for high precision applications.

  • Lack of sliding friction between the nut and screw ensures an extended lifespan, and reduces downtime for maintenance and part replacement.
  • Ball screws can operate with some pre load which eliminates backlash between input and output.

Ball Screw Nuts

Ball Screw nuts contain miniature ball bearings which roll around the thread of the Ball Screw to aid movement. These are suitable for applications that require high load or high precision due to their contact with the screw.

  • Customers should be careful when placing the Ball Nut on the screw and should use the sleeve provided.
  • To ensure long lifetime, care is needed to avoid contamination with dirt and abrasive particles.
