Industrial Long Stroke Electric Telescopic Cylinder is mainly used in the following scenarios:

‌Heavy Machinery and Mining Equipment‌

For example, the lateral hydraulic cylinders of mining dump trucks and cranes need to withstand extrem

e loads (such as handling 30 tons of aluminum coils) and long strokes (up to 12 meters).

‌Automated production line‌

Machining equipment used for high-precision positioning, such as tool drives in fast axis servo systems 

(FAS), combine with gas hydrostatic bearings to achieve micron-level motion control.

‌Intelligent warehousing and logistics‌

To achieve intensive storage of goods such as aluminum coils in heavy-duty stackers, it is necessary to 

adapt to high temperature environments (200°C) and maintain millimeter-level positioning accuracy‌

‌Industry 4.0 Equipment‌

As the driving unit for Industry 4.0 core components such as CNC machine tools and additive manufact

uring (3D printing), it supports efficient and low-energy production‌

The Industrial Long Stroke Electric Telescopic Cylinder is an electromechanical linear drive device integrating

 a servo/stepper motor, reduction gear transmission mechanism, ball/trapezoidal lead screw, cylinder, and 

piston rod. It converts circular motion into linear reciprocating motion of the piston rod through motor rota

tion driving the lead screw transmission. It can precisely control the extension stroke, speed, and thrust, and

 can replace traditional hydraulic cylinders and pneumatic cylinders to complete linear reciprocating motion

3. **High Load Capacity:** The optimized electric cylinder profile combined with built-in guide rails allows it 

to withstand extremely high forces and torques. Some models can maintain a maximum holding force of 

1200N, making them suitable for heavy-duty, high-impact industrial applications.

4. **Excellent Environmental Adaptability:** With an IP 69k protection rating, it can operate stably in temper

atures ranging from -20℃ to +65℃. Its sealed structure prevents dust and liquids from entering the cylinder, 

extending the equipment's lifespan.

5. **Compact Structure:** The equipment is compact in its retracted state, facilitating installation in space-

constrained environments. It requires no complex piping, making installation and maintenance convenient.

Electric cylinders with a 50mm bore diameter represent a standard specification widely utilized in automated production within the 3C electronics industry.

Most processes in the 3C sector involve light-to-medium loads and demand high precision. Servo electric cylinders with a 50mm bore typically offer a thrust range of 1–5 kN—a range that perfectly aligns with the thrust requirements of the majority of scenarios encountered in 3C manufacturing. This specification is well-suited for various operations, such as the pressing of mobile phone camera modules, the assembly of battery components, the positioning required for chip packaging, and the drilling and soldering of PCB boards.

Furthermore, the 50mm-bore electric cylinder features a compact footprint; this allows it to meet the spatial constraints for integration into small-scale automated equipment and robotic modules, while simultaneously satisfying requirements for both thrust stability and precision. Its repetitive positioning accuracy can be consistently maintained within ±0.01 mm—a level of performance that fully meets the micron-scale precision standards demanded by 3C production—which is why it has been so widely adopted throughout the industry.
