When selecting the appropriate size of a linear actuator, applying one general number to make a selection, such as a maximum load rating, is difficult.

From improved task flexibility and miniaturization to higher load capacity and advanced controller technology, hexapod positioning systems are becoming more common in multiple industries. Though not new to the market, these versatile motion systems solve many industrial automation challenges, from semiconductor applications to automotive assembly lines.

Today's linear motion and automation challenges require higher precision and faster speeds.

Can-stack linear actuators from Helix Linear Technologies leverage permanent magnets and stepper motor operation to convert rotary motion into linear motion.

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.
