skyveaktuator

A skyveaktuator is a type of linear actuator designed to generate controlled sliding motion along a straight axis. It is commonly used to position components in automation, robotics, and machine tools, where precise, repeatable displacement is required.

A skyveaktuator operates by converting energy from electric, hydraulic, or pneumatic sources into linear motion through a drive mechanism such as a leadscrew, ball screw, belt drive, rack-and-pinion, or a linear motor. Core components typically include a fixed housing, a sliding carriage, guides or rails, end stops, and a feedback sensor system to monitor position.

Variants range from high-precision electric screw actuators suitable for metrology and CNC applications to fast, high-force hydraulic or pneumatic slide actuators used for clamping and positioning. Electric variants often employ encoders and servo control for closed-loop positioning, while simpler open-loop configurations may use limit switches.

Common applications include automation cells, pick-and-place machines, packaging lines, laboratory instrumentation, and adjustable fixtures. In some consumer products, compact skyveaktuator devices are used for drawer and door sliding mechanisms or adjustable seating.

Advantages of skyveaktuators include precise, repeatable motion and good load support, with the ability to hold position under power-off conditions in some designs. Limitations include mechanical wear, friction, lubrication requirements, and sensitivity to contamination and temperature. Selection depends on required speed, force, travel range, and the overall control architecture.
