Linear Actuators

Electromechanical actuators convert electrical energy into mechanical energy. The common types of electromechanical actuators by their energy conversion mechanism are electromagnetic, electrostatic, and piezoelectric. In electromagnetics, the air gap separates a stationary member and a moving member of an electromechanical actuator. The amount of energy per unit volume of air gap for magnetic fields can be five orders of magnitude higher than that of electric fields. The advantage of electrostatic is the higher switching rate and less energy loss. Electrostatic actuation is the main actuation for moving charged toner particles in electrophotographic processes. Piezoelectric is the property of certain crystals that produces a voltage when subjected to mechanical deformation, or undergoes mechanical deformation when subjected to a voltage.

Screw Jacks (Mechanical Actuators) are used in linear motion applications to push,pull,lift or lower loads for actuation and precise positioning purposes.They are available in Metric or Imperial designs with load rating from 5kN to 3500kN,using machine screw,ball screw or roller screw drives in single face,cubic or corrosion resistant housings.

Power jack range of mechanical jacks (Including ratchet,rack & pinion,spindle and journal types),rail jacks,hydraulic jacks and winches are ideal for general lifting and positioning applications.They are used worldwide in wide variety of material handling applications covering most industry sectors.
