Acme screws are a mainstay for supplying motion and positioning control in many types of machinery, including CNC milling machines, lathes, syringe pumps, linear actuators, 3D printers, and robotic systems.

The coefficient of friction, wear life and resulting torque to drive acme screws and acme screw assemblies are highly controlled by the ability of the engineered plastic to supply sufficient lubrication to the nut and screw interface.

In short, a linear actuator is a device that creates linear (straight) motion. From highly complex applications to the simplest button pressing application, small linear actuators are used everywhere!

Lead accuracy is the difference between the actual distances traveled versus the theoretical distance traveled based on lead. Obviously, the better the lead accuracy, the better precision you have.

The acme thread form, established over 100 years ago, replaced square thread screws, which had straight-sided flanks and were difficult to manufacture.

There are so many benefits of using PTFE coated screws to improve and enhance your products and applications. Before we get into some benefits of choosing PTFE coated screws, here's some more information on the product itself:

Not sure which material to use for your acme nuts? Learn the basics of the materials used in acme nuts and how to compare them with our helpful PowerPoint that we have created for you. Please note that all Helix materials used have been selected for low friction, minimum wear, long life and clean operation.

Lead screws are a lower cost linear motion solution than any other mechanical, pneumatic or hydraulic product. Precision lead and acme screws are manufactured from special high carbon alloy steels and anti-corrosive stainless steels that lend themselves to precision thread-rolling processes and to the demanding applications where engineers apply them.

Nook Industries, a leading manufacturer of linear motion control systems and components, today announced the formation of HELIX Linear Technologies, a wholly owned subsidiary and production facility that dramatically expands the capacity and medical industry focus of the company’s lead screw operations.

We’re excited to announce that our new and refreshed website is live. The updated site includes several new lead screw and linear actuator products that deliver smooth, clean and quite linear motion solutions.
