Electric linear
A servo motor turns a screw. A guided nut translates that rotation into controlled rod travel, supported by thrust bearings and position feedback.
3D model and components
Servo motor → coupling → screw → guided nut → rod

What each part does.
Power path: Servo motor → coupling → screw → guided nut → rod.
- Drive & position feedback
- Motor feedback and linear position sensing establish the commanded travel.
- Servo motor & coupling
- The motor transfers torque to the screw through an aligned coupling.
- Screw & nut
- A ball-screw or roller-screw mechanism converts rotary input into axial motion.
- Thrust bearing pair
- Axial reaction loads return through the screw support bearings into the housing.
- Guided nut & rod
- The guide prevents nut rotation, allowing the output rod to translate.
- Tube & anti-rotation guide
- The housing supports alignment, reacts load and protects the translating assembly.
Machines that call for it.
Factory automation
Handling and assembly cells bring rotary indexing, linear transfer and end-effector motion into one coordinated process.
See the application 02Machine tools
Machine-tool rotary axes need a stiff load path and stable positioning. Direct-drive architectures remove a gear stage while preserving the need for bearings, feedback and thermal control.
See the application 03Aerospace & defence
Aerial platforms combine propulsion, payload pointing and deployable mechanisms. Larger flight-control loads may call for electric linear or electro-hydrostatic actuation.
See the application 04Special-purpose machinery
Parallel motion platforms combine coordinated linear axes to position a payload in multiple degrees of freedom. Geometry, joint articulation and calibration determine the usable workspace.
