Características y aplicaciones del producto

The SJA series screw jack converts rotary motion into linear lifting/pushing, featuring strong self-locking, high precision and compact structure. Widely used in industrial automation, metallurgy, stage, medical and other scenarios, it supports 0.5-100 ton loads, multiple drive modes and synchronous linkage to meet diverse industrial drive needs.

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

Clean & Eco-Friendly: No hydraulic oil or air supply required, eliminating leaks and pollution, ideal for food, medical, and cleanroom environments.
Precise Control: Enables accurate position and speed adjustment via motor control, with high repeat positioning accuracy.
Energy Efficient: High operating efficiency with zero standby power consumption, more energy-saving than traditional cylinders.
Flexible Installation: Compact structure allows flexible layout, suitable for space-constrained applications.
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
