Product Overview

An electric linear actuator is an electromechanical device that converts the rotary motion of a motor into linear reciprocating motion. It consists of a motor, reduction gears, lead screw/ball screw, nut, push rod, and limit switches, enabling various actions such as pushing, pulling, lifting, tilting, and adjusting. Widely used as a cleaner, more precise, and energy-saving alternative to pneumatic and hydraulic cylinders.

2. Structure & Working Principle

  • Power Unit: The drive motor provides rotational power.
  • Transmission Mechanism: Reduction gears reduce speed and increase torque.
  • Actuating Mechanism: Lead screw/ball screw and nut convert rotary motion into linear motion, driving the push rod.
  • Safety Protection: Built-in limit switches prevent over-travel damage, ensuring stable operation.

3. Key Advantages

  1. Clean & Eco-Friendly: No hydraulic oil or air supply required, eliminating leaks and pollution, ideal for food, medical, and cleanroom environments.
  2. Precise Control: Enables accurate position and speed adjustment via motor control, with high repeat positioning accuracy.
  3. Energy Efficient: High operating efficiency with zero standby power consumption, more energy-saving than traditional cylinders.
  4. Flexible Installation: Compact structure allows flexible layout, suitable for space-constrained applications.
  5. Low Maintenance: No complex hydraulic/pneumatic piping; maintenance is limited to regular lubrication checks.

4. Typical Applications

  • Industrial Automation: Equipment pushing/pulling, lifting platforms, station adjustment, automated production lines
  • Medical Equipment: Hospital beds, rehabilitation devices, operating table adjustment
  • Smart Home: Electric sofas, standing desks, smart windows/doors
  • Automotive Industry: Power tailgates, seat adjustment, equipment compartment door control
  • Other Scenarios: Stage equipment, storage racks, gardening equipment, livestock machinery
