Servo-driven actuators designed to replace pneumatic and hydraulic cylinders

Lenze (also Techdrives) : 07 February, 2015  (New Product)
The new Linear-Mech SA range of servo-driven actuators fron Techdrives is designed to take the place of pneumatic and hydraulic cylinders by giving better performance, higher precision and substantial energy savings.
Servo-driven actuators designed to replace pneumatic and hydraulic cylinders
The SA range comprises seven sizes of ball screw actuators driven by servo motors. The square profiles and mounting options meet the standard ISO 15552 and two options exist for parallel or in-line motor mounting. Dynamic loads are in the range 100 to 40000N. As electrical energy is only used when the actuator is moving, energy savings of up to 90% are possible compared to pneumatic and hydraulic cylinders. Furthermore installation is easier and oil leakage is not a problem.
 
Each model features a rolled ball screw to IT7 accuracy, higher accuracies up to IT3 are possible on request. A zero backlash option can be specified for high precision positioning. Brushless servo motors with brakes and encoders together with matching drives are part of the package and motion controllers are optional. Servo drive technology combined with precision ball screws makes possible precision positioning with accuracies up to +/-0.01mm.
 
Linear-Mech SA Servo Driven Actuators are built to order with strokes from 100mm up to 1.5m. Linear speeds usually start at 50mm/s and extend up to 1.5m/s. With capacity for 100% duty cycles these electromechanical cylinders are a good fit for automated machinery that needs precise, repeatable and high speed linear motion. As clean devices, they are suitable for use in food production environments and they can make big reductions in energy consumption. Further information and technical advice is available in the UK from Techdrives.
