About Ewellix
Ewellix Linear Motion & Actuation SolutionsSchaeffler
Ewellix, now owned by the Schaeffler Group (completed acquisition January 2024), is a global innovator in electromechanical linear motion and actuation solutions serving assembly automation, medical device manufacturing, mobile machinery, and industrial robotics across 16 global sales units and eight production facilities. Headquartered in Gothenburg, Sweden, Ewellix combines precision ball-screw and roller-screw technology with brushless DC and AC motor integration to replace hydraulic cylinders with efficient, silent, and maintainability-friendly electric actuators.
Ewellix's core product portfolio includes the MATRIX series of compact AC and DC linear actuators designed for medical devices, surgical robotics, and precision industrial automation; the LEMC series of high-performance roller-screw actuators engineered to replace hydraulic systems in mobile machinery (excavators, wheel loaders) with electric power; the EMA-100 series for heavy-load applications in compact spaces; and comprehensive ball-screw, pillar, and linear-bearing components supporting custom integrator designs.
The MATRIX series delivers high force density (up to 5,000 N push/pull) in compact 30-50 mm housings with dual-rod, single-rod, and rodless configurations, available in 12VDC, 24VDC, 48VDC, 115VAC, 120VAC, 220VAC, and 230VAC versions. LEMC roller-screw actuators are rated for loads exceeding 20,000 N with integrated gearbox and motor, ideal for mobile hydraulic replacement and achieving 30-40% energy savings over equivalent pneumatic systems.
All Ewellix actuators feature integrated or modular feedback sensors (potentiometer, proximity, LVDT), IP54-IP67 sealed housings for washdown and outdoor use, and stainless-steel or anodized-aluminum construction for food, pharmaceutical, and maritime applications. Stroke lengths range from 50 mm (compact medical devices) to 1,200 mm (industrial automation); speed control from 5 mm/s (precision) to 500 mm/s (high-speed pick-and-place).
ChatMRO's AI instantly matches your load requirement (N), desired stroke length (mm), voltage supply, speed requirement (mm/s), and environmental protection (IP rating) to the right Ewellix actuator series, configuration, and motor type. No engineering calculation needed—describe your motion need and get instant actuator recommendations with lead times and cross-reference compatibility data.

Frequently asked questions
What's the key advantage of Ewellix LEMC roller-screw actuators over ball-screw designs for mobile equipment?
LEMC roller-screw actuators (patented triple-screw design) offer 2-3x greater load capacity and lower internal friction than ball screws in the same envelope, enabling force outputs to 20,000+ N with minimal motor power draw. Roller screws self-lock under load, preventing backdriving and eliminating the need for load-holding solenoids—critical for excavator booms and wheel-loader lifting arms where loss of position during power loss is a safety hazard. This mechanical advantage makes LEMC the electric alternative to hydraulic cylinders in heavy mobile machinery.
How do I select between Ewellix MATRIX (compact) and EMA (heavy-duty) actuators for industrial automation?
MATRIX series prioritizes size and weight (30-50 mm, 100-500 g) for medical devices, surgical robots, and space-constrained pick-and-place arms, with forces to 5,000 N. EMA series targets loads above 5,000 N in industrial assembly (automotive sub-assembly, appliance final-assembly) where motor power and stroke length are less constrained; EMA-100 handles continuous duty cycles and outdoor washdown exposure better. Choose MATRIX for medical/precision; EMA for high-load industrial volume production.
Can Ewellix actuators replace hydraulic cylinders in my existing mobile equipment control circuits?
Yes, Ewellix LEMC actuators are engineered as direct hydraulic cylinder replacements with equivalent force ratings, feedback sensor integration, and sealed housings for hydraulic-hose-routed piping applications. However, you must adapt solenoid control logic: hydraulic directional valves switch instantly (milliseconds), while LEMC proportional solenoids control motor speed gradually (100s of milliseconds). Reprogramming PLC ramp profiles and adding integrated limit-switch feedback ensures smooth equipment operation and extends component life by eliminating shock loads inherent to on-off hydraulic switching.
What power supply voltage should I specify for an Ewellix actuator in a distributed automation system?
Ewellix offers 12VDC (battery-powered, mobile robotics), 24VDC (industrial control systems, low-voltage safety standard), 48VDC (high-power systems, reduced wiring cost for long distances), 115VAC/120VAC (US standard industrial), and 230VAC (European standard). Choose 24VDC for new installations requiring safe-extra-low-voltage (SELV) classification per IEC 61010; existing 115VAC or 230VAC industrial plants should specify matching voltage to avoid costly distribution upgrades. Ewellix motor controllers support soft-start ramps, reducing inrush current and allowing undersized existing power supplies to handle new automation additions.
How do I program speed control and force feedback into my automation system using Ewellix actuator sensors?
Ewellix MATRIX and LEMC actuators integrate potentiometric or LVDT linear position sensors (0-10V analog output) feeding back instantaneous position to your PLC or motion controller. Motor speed is controlled via 0-10V command input (proportional voltage = proportional speed), enabling smooth acceleration, variable-speed process control, and endpoint deceleration. Load feedback requires optional force-sensing load cell between actuator end-effector and workpiece; ChatMRO's integrated partner network includes PLC programming services and sensor calibration expertise for turnkey automation integration.
