Helix Linear Blog - Acme Screws, Lead Screws, metric lead screws, Linear actuators

Although the term “linear actuator” can be defined broadly as any mechanical device that converts energy into controlled, straight-line motion, the definition narrows in the context of devices used for medical treatment and biomedical/chemical research.

A stepper motor is one of the most common motors used in motion control applications, primarily positioning applications.

Linear actuators have a variety of applications depending on the industry. Helix Linear's actuators can be used for any application requiring linear motion. Our actuators are pre-engineered, assembled, tested and ready to use making it the best economical and time sensitive approach to low cost automation. While we’re sure you’re thinking, “That’s great!” And it is, we’re sure there are many more questions to answer so keep scrolling below to find your answers.

Acme lead screw assemblies are used to convert rotary motion into linear motion by turning the screw or the nut. One of the most popular types of lead screws uses the Acme thread form which typically has an included thread angle of 29°.

When it comes to actuators for motion control applications, there are several types to choose from. These include pneumatic, hydraulic, electric, or electro-mechanical.

The reason electric linear actuators are a preferred choice for converting rotary motion into linear motion is that they have many advantages.

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 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.
