Linear Guide Rail Systems are perhaps the most diverse group of products in the motion control industry.

Helix Linear Technologies designs and manufactures custom lead screws and Acme screws in a variety of materials, including stainless steel, alloy, titanium, and aluminum.

Lead screws from Helix Linear Technologies are widely used in additive manufacturing applications (commonly known as 3D printing) what's not so common -- the location of one of those recent projects. Our precision lead screws are now driving results 250 miles above the Earth inside NASA's Refabricator project.

Whatever the motion control requirements, linear actuators and leadscrew assemblies play a crucial role in material handling, packaging, and food processing equipment.

Our Acme threaded rods start in long lengths that can be shipped to you as-is or cut and machined to your specifications.

When people hear the word Acme, many conjure up the image of the Acme brand products used by Wile E. Coyote. While Acme products may have had a generic connotation and produced substandard results as demonstrated in the Coyote's experience, Acme, as we know it today, is the exact opposite.

For a lead screw linear actuator to convert rotary motion into linear motion, there must be an anti-rotation element on the nut design where the lead screw is rotating. The anti-rotation feature applies to an external linear actuator design as well. However, for captive and non-captive linear actuators where the nut is integral to the rotor and confined within the motor, the lead screw is prevented from rotating to translate rotary motion into linear motion.

Lead screws are used in multiple types of medical imaging applications. Find out how they are used and what type of lead screw works in each type of imaging machine here.
