Linear actuatordefinition and typeDefinition: Electro-mechanical linear actuatorsenable precise, controlled, and repeatablepush/pull movement in linear driveapplications (see illustrations below).Linear actuators serve as efficient, virtuallymaintenance-free, and environmentallyfriendly alternatives to hydraulic or pneumatictypes.Standard versions can handle loads asgreat as 12 kN, deliver speeds up to150 mm/s, and travel as far as 1 500 mm.They can be self-contained in aluminum,zinc, or polymer housings and ready-tomountfor easy plug-in operation.Actuators with modular design and openarchitecture offer opportunities to chooseand integrate components to achieve customizedsolutions within existing envelopes.Application potential expands with the introductionof technologies for specific purpo–ses, such as hall sensors, limit switches, potentiometers,friction clutches, or back-upnuts.Screw-type linear actuators powered byan electric AC or DC motor basically consistof a lead screw (threaded shaft/spindle) withdrive nut and push tube. In 90 % of the cases,a gearbox between the motor and thescrew is also present.When power is supplied, the motor rotatesthe lead screw, which causes the drivenut to travel and extend the push tube. Reversingthe motor rotation retracts the pushtube.Pushing/pulling1 2 75Opening/closing364Legend:1. Motor2. Gearbox3. Screw and nut4. Protection tube5. Push tube6. Front attachment7.
