Electric Linear Actuators description

Electric Linear Actuators as an alternative to pneumatic cylinders or hydraulic cylinders. Electric linear cylinders are self-locking linear drives, which means that no power is supplied when at a standstill, easy installation with two trunnion mounting feet, no pipework, powerpack and valves, low power consumption and running costs, no oil leaks, contamination or fire risk, low noise system, higher dynamic capacity, higher speed capability and longer life. These make jacton electric cylinders an interesting alternative to pneumatic and hydraulic actuators. 


Electric Linear Actuators are consists of either a ACME screw and nut, driven by an electric motor, through a reduction gearbox. The lead screw converts rotary motion to linear movement. As the screw rotates, the nut extends and retracts the ram, which is attached to the load. There are two designs for Electric Linear Actuators, they are LAP Series parallel motor mount Electric Linear Actuators, and LA Series in line motor mount Electric Linear Actuators. LAP Series parallel configuration Electric Linear Actuators load capacities are from 100 kgf to 15 tons, travel speeds up to 84 mm/s, rated power of motor is from 0.18kw to 18.5kw. LA Series in-line configuration Electric Linear Actuators load capacities are from 10 kgf to 1000 kgf, travel speeds up to 85 mm/s, rated power of motor is from 0.06kw to 1.5kw. For all jacton Electric Linear Actuators with no standard stroke, all travel length is built to your specifications. The most common motor type is three-phase AC motor - 220V, 240V, 380V, 400V, 415V, 460V, and 480V. With stroke limit switches to control different travel length.
