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.

Linear actuators are mechanical devices used to generate motion in a straight line. Linear actuators can be lead screw driven and are used in a wide variety of industries and applications to convert rotary motion to linear motion.

Electric Cylinders (or electro-mechanical cylinders) are captive linear actuators designed as a modular system. Due to lower maintenance costs, enhanced motion control, and a long list of additional benefits, electric cylinders are rapidly replacing pneumatic cylinders in multiple industries.

Linear motion positioning applications can often be addressed with a single-axis linear stage consisting of a moving rail, a fixed base, a carrier plate, and a linear actuator. However, a sizable number of applications require linear motion on multiple axes.

Can-stack stepper actuators offer an economical linear motion solution in a small package.

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.

Stepper motor driven screw linear actuators have been used for a while in a variety of applications. Integrated motor screw units used to only be available in high volume runs or too costly to consider. Building your own with expensive couplings and support bearings, mounting and aligning the assembly – add up to overwhelming costs.

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.
