A servo electric cylinder is a modular product integrating a servo motor and screw. It converts motor rotation into linear motion and transforms precise speed, revolution, and torque control into precise linear speed, position, and thrust control, creating a high-performance solution for accurate linear motion.
Features
Closed-loop servo control provides positioning accuracy up to 0.01 mm. With a pressure sensor, thrust-control accuracy can reach 1%. The cylinder connects easily to PLCs and other control systems for high-precision motion control. It offers low noise, energy efficiency, clean operation, high rigidity, impact resistance, long service life, and simple operation and maintenance. Protection can reach IP66 for reliable operation in harsh environments. High-load, high-speed, high-accuracy positioning is smooth and quiet, supporting papermaking, chemical processing, automotive, electronics, machinery automation, welding, and many other industries.
Low maintenance cost: In complex environments, only periodic grease lubrication is normally required. With few wear components to replace, after-sales maintenance cost is significantly lower than for hydraulic and pneumatic systems.
An effective replacement for hydraulic and pneumatic cylinders: Servo electric cylinders provide cleaner, more energy-efficient operation and integrate readily with PLCs for high-precision motion control.
Flexible configuration: Available mounting options include front, rear, and side flanges; rear clevises; trunnions; and guide modules. Motors may be mounted inline or in parallel. Options include limit switches, planetary reducers, and preloaded nuts. Drive choices include AC brake motors, DC motors, stepper motors, and servo motors.
Types
1. Inline electric cylinder: Integrates an AC servo motor, servo drive, high-precision ball screw, and modular construction. Direct motor-to-screw connection reduces inertia and backlash, improving control and positioning accuracy. The assembly is compact, responsive, quiet, easy to install, and reliable.
2. Folded-back electric cylinder: Its short overall length suits restricted installation spaces. A high-strength synchronous belt provides minimal backlash and long life. The motor and cylinder can be configured flexibly for easy installation and setup.

Summary of Advantages
- Accurate path positioning and controllability
- Modular combinations that save machine-design space
- Suitable for high-speed, high-frequency operation
- Precision construction and convenient installation
- Multi-point positioning and multi-stage control
- Multiple mounting accessories and installation methods
- Compatible motor-and-controller packages
- Broad product selection
- Simple design and low maintenance cost
Operating Instructions and Precautions
- This is precision electromechanical transmission equipment. Read the cylinder, motor, drive, and component instructions carefully before use.
- The product contains high-strength magnets and external magnetic-induction switches and stroke-limit marks. Adjust the required stroke only within the marked range.
- A fully sealed structure and high-quality grease are used, so routine customer maintenance is generally unnecessary. Personalized high-speed/high-frequency versions include grease inlets where required.
- During commissioning, begin with low-speed jogging. Increase speed only after all functions are confirmed normal to avoid cylinder damage.
Applications
- Entertainment: robotic arms and joints, motion seats, and related equipment
- Defense: flight and other simulation systems
- Automotive: press-fitting machines and test instruments
- Industry: food, ceramic, and welding machinery; lifting platforms; and other automation equipment
