The long-stroke industrial linear actuator is a specialized electric linear motion device designed for extended-distance reciprocating movement and large-displacement industrial automation scenarios. Different from standard short-travel actuators, this upgraded model is structurally optimized for ultra-long stroke operation, effectively solving the problems of insufficient travel, limited layout and displacement restriction of conventional linear actuators. Adopting high-strength telescopic transmission structure and industrial-grade motor drive, it delivers stable thrust, ultra-smooth linear motion and long-cycle continuous working capacity. With clean electric drive, no hydraulic oil pollution and low maintenance requirements, it has become the preferred replacement for traditional hydraulic and pneumatic cylinders in long-travel automated industrial systems.

The long-stroke industrial linear actuator adopts a multi-stage telescopic integrated internal structure, with all core components optimized for anti-deflection, anti-shake and long-stroke stability. The modular assembled structure features high rigidity, compact layout and strong durability, adapting to long-distance frequent reciprocating operation:

High-precision Ball Screw Transmission Assembly: Equipped with large-lead precision ball screw as the core transmission component, featuring low friction, high transmission efficiency and long fatigue life. The optimized screw rigidity design effectively avoids bending and deflection during ultra-long stroke extension, ensuring consistent linear motion accuracy.

Multi-stage Telescopic Outer Cylinder: Adopts multi-layer nested high-strength alloy tube structure. The graded telescopic design realizes ultra-long stroke output while controlling the retracted overall length, saving installation space and solving the layout dilemma of long-travel equipment.

Industrial-grade Drive Motor Module: Integrated sealed motor structure, tightly combined with the transmission system. It provides stable and lasting power output, avoiding power attenuation and jitter during long-distance extension movement.

Reinforced Guide & Anti-rotation Mechanism: Built-in precision linear guide rail and anti-rotation limit structure, which completely limits the radial rotation of the telescopic tube. It ensures pure linear displacement without torsion or lateral deviation during full-stroke operation.

Multi-layer Sealing & Dustproof System: Equipped with high-density dust ring, oil seal and waterproof protective sleeve. It effectively isolates workshop dust, moisture and oil dirt, preventing internal component wear and ensuring stable operation in long-cycle working conditions.

Built-in Overload & Limit Protection Device: Integrated upper and lower stroke limit sensors and current overload protection modules. It automatically cuts off power when reaching the limit position or overloaded, protecting the screw and motor structure from damage.

This long-stroke linear actuator supports diversified electric input and control methods, adapting to different industrial automation control systems and long-travel working requirements, realizing flexible and intelligent linear motion control:

Standard Constant-speed Electric Input: Matched with ordinary industrial AC and DC motors, realizing fixed-speed reciprocating linear movement. Suitable for conventional automated equipment with stable stroke and single-process operation.

Variable Frequency Speed-regulating Input: Compatible with frequency conversion control system, realizing stepless speed adjustment. It supports fast extension and low-speed precise positioning in long-stroke travel, meeting multi-process production demands.

Servo Precision Control Input: Matched with servo drive system, realizing closed-loop precise positioning, fixed-distance stroke control and synchronous linkage. It is applicable to high-precision long-travel automation scenarios with strict displacement tolerance requirements.

Remote Programmable Control Input: Support PLC signal access, remote control and automatic cycle operation. It can set arbitrary stroke positions and working cycles, realizing intelligent unmanned operation of long-travel motion.

Manual Emergency Debugging Input: Reserved manual debugging interface, which can manually control the extension and retraction of the actuator during equipment shutdown and maintenance, facilitating on-site stroke calibration and fault inspection.

To adapt to various long-travel pushing, pulling, lifting and hinged swing scenarios, the long-stroke industrial linear actuator is equipped with multiple interchangeable rod end heads, covering all industrial connection modes:

Flat Top Head: Smooth flat end surface, used for vertical top pressure and linear jacking. It features uniform stress and simple installation, suitable for platform lifting and vertical support with long stroke.

External Threaded Head: Standard industrial thread design, which can be directly locked and connected with fixtures and flanges. It is applicable to long-distance tension and compression dual-load working conditions.

U-shaped Fork Head: Hinged pin hole structure, allowing small-angle swing and tilt movement. It is widely used for long-stroke overturning mechanisms, angle adjustment and swing type automation equipment.

Front Flange Mounting Head: Integrated circular flange plate at the rod end, realizing bolt fixed installation. It has high connection rigidity and strong anti-loosening performance, suitable for long-term stable long-travel positioning equipment.

Earring Hinge Head: Double-ear hinge structure, used for floating connection and multi-angle stress adaptation. It can offset tiny installation errors and avoid structural jamming during long-stroke reciprocating movement.

Relying on ultra-long stroke output, stable thrust performance and intelligent control advantages, long-stroke industrial linear actuators are widely used in industrial scenarios requiring large-displacement linear movement, replacing traditional hydraulic and pneumatic devices with cleaner and more efficient electric motion solutions:

Automated Production Lines: Long-distance lifting of large assembly platforms, full-stroke displacement adjustment of conveyor equipment, and reciprocating pushing of automated feeding mechanisms, solving the travel limitation of standard actuators.

Logistics & Warehousing Equipment: Long-travel lifting of intelligent stereoscopic warehouse shelves, full-stroke stretching of loading and unloading platforms, and height adjustment of large-scale sorting equipment, realizing long-distance stable material handling.

Stage & Entertainment Facilities: Ultra-long stroke lifting of large stage platforms, stretching adjustment of exhibition display stands, and displacement control of simulation motion platforms, with smooth and jitter-free operation.

Construction & Environmental Protection Machinery: Long-distance pushing and lifting of environmental protection dust removal equipment, stroke adjustment of construction auxiliary machinery, and opening and closing control of large industrial doors and baffles.
