Turning Electric Linear Cylinder

LIND LDC180 Heavy-Duty Turning Electric Cylinder

The Lind LDC180 heavy-duty turning electric cylinder is a large-tonnage electric actuator specially designed by Wuxi Lind Automation Technology Co., Ltd. for extreme heavy-duty working conditions. It adopts a high-performance roller screw drive and a precision rotary transmission structure, efficiently converting the rotary motion of the servo motor into powerful linear thrust. This fills the technological gap in domestically produced large-tonnage electric cylinders in the fields of extreme heavy loads and ultra-long strokes, providing an ideal drive solution for heavy industrial automation that combines precision and power.

· Maximum Thrust: 50 tons (approximately 500 kN)

The LDC180 heavy-duty electric cylinder features an iron cylinder barrel and a high-rigidity steel push tube structure, paired with a high-performance roller screw. A single cylinder can deliver a thrust of up to 50 tons, easily handling ultra-high load operations such as stamping, press fitting, and lifting. It is suitable for replacing traditional hydraulic systems in heavy-duty applications.

· Maximum Stroke: 5 meters (5000 mm), Customization Available
Lind electric cylinders cover strokes from 15mm to 8000mm. The LDC180 supports a customized 5-meter ultra-long stroke, meeting the stringent requirements of large equipment, long-distance material handling, and special working conditions for ultra-long strokes.

· Repeat Positioning Accuracy: ±0.02mm
With closed-loop servo control and a high-precision encoder, position control accuracy reaches 0.01mm, and thrust control accuracy reaches 1%, achieving precise closed-loop control of speed, position, and force.

· Operating speed: Up to 250mm/s.

Compatible with AC servo motors (1000W~7500W) and planetary gear reducers (1:3~1:20), flexibly adapting to different speed and torque requirements under various operating conditions.

 

The LDC180 features a folding transmission structure that saves installation space：

It transmits motor power to the lead screw via a synchronous belt or reducer. The motor and cylinder are arranged parallel to each other, significantly reducing the axial length compared to traditional linear electric cylinders, offering a significant advantage in applications with limited axial space. The high-performance roller screw drive provides high transmission efficiency and strong load-bearing capacity, ensuring smooth operation while meeting the demands of high thrust output.

High-strength iron cylinder barrel + steel push tube, adaptable to harsh working conditions：

The iron cylinder barrel, combined with the steel push tube and protective tube, forms a robust and durable overall structure with strong impact and torsional resistance, enabling long-term stable operation in harsh environments with high intensity and frequent reciprocating motion.

Anti-rotation guiding design:

The built-in movable guide rail anti-rotation mechanism effectively prevents the push tube from rotating during extension, ensuring the stability and positioning accuracy of linear motion.

Modular design for easy maintenance:

Adopting a modular design concept, the roller screw nut can be directly re-lubricated without disassembling complex components, significantly reducing subsequent maintenance costs and downtime.

 

· Precise and Controllable:

Precise closed-loop control of speed, position, and thrust, with force control accuracy up to 1%, meeting the stringent force and position requirements of applications such as precision press fitting and testing.

· Green and Environmentally Friendly:

Fully electric drive, zero hydraulic oil leakage, zero air source pollution, reducing energy consumption by up to 90% compared to traditional hydraulic systems, aligning with green manufacturing and carbon neutrality trends.

· Durable and Reliable:

Utilizing high-quality materials and advanced manufacturing processes, with no easily damaged hydraulic seals, resulting in significantly lower maintenance costs throughout the entire lifecycle compared to hydraulic cylinders.

· Wide Temperature Range Adaptability:

Adaptable to a wide temperature range of -45℃ to 80℃, unaffected by oil temperature changes or low ambient temperatures, maintaining stable output even in extremely cold and high-temperature environments.

· Flexible Customization:

Compatible with various motor and reducer combinations, allowing for customization of installation interfaces, stroke, speed, and other parameters according to customer operating conditions.

 

· Heavy-duty press fitting and stamping:

Replaces traditional hydraulic presses for heavy-duty press fitting operations such as automotive parts press fitting, sheet metal stamping, and mold clamping.

· Large material handling and lifting:

High-load linear motion applications such as heavy-duty platform lifting, large component transfer, and warehouse stacking.

· Iron and steel metallurgy:

High-temperature, heavy-duty conditions such as continuous casting equipment, rolling mill adjustment, and furnace door opening and closing.

· Shipbuilding and heavy machinery:

Applications such as hatch opening and closing, large valve control, and heavy-duty robotic arm drive.

· Precision testing and simulation:

Testing equipment requiring high force and position accuracy, such as large-tonnage material testing machines and heavy-duty simulation platforms.

· New energy equipment manufacturing:

Emerging fields such as heavy assembly in battery production lines and wind power equipment manufacturing.

 

 

1. Flexible Rotation

The built-in pivot joints allow the cylinder to swing freely with the load, ensuring smooth operation without mechanical jamming.

 

2. High-Load Capacity

Reinforced housings and thickened screw rods provide massive thrust, maintaining a stable stroke even under maximum pressure.

 

3. Long-Term Durability

Hardened transmission components and premium industrial seals enable millions of cycles with minimal mechanical wear.

 

 

For ultra-heavy-duty applications, load capacity and lifetime are critical factors.

Compared with traditional lead screws or standard ball screws, the roller screw structure uses multiple threaded rollers to distribute load over a larger contact area, significantly improving load capacity, shock resistance, and service life.

For the LDC180, the roller screw drive enables:

• Higher thrust density for 50-ton class applications

• Better performance under continuous heavy loads

• Reduced wear during frequent reciprocating motion

• Stable accuracy retention over long operating cycles

This makes it especially suitable for heavy press fitting, forging equipment, testing systems, and large automation platforms where reliability is more important than simple speed.

 

Large-tonnage electric cylinders usually require a long motor-cylinder arrangement, which increases equipment footprint.

The LDC180 adopts a fold-back transmission layout, placing the motor parallel to the cylinder body through a synchronous belt or reducer transmission system.

Compared with traditional inline structures, this design provides:

• Shorter installation length for limited machine space

• Easier integration into existing hydraulic cylinder replacement projects

• Better flexibility for equipment layout optimization

• Reduced interference with surrounding mechanical structures

The fold-back design allows heavy-duty electric actuation to be installed in compact industrial systems without sacrificing thrust performance.

 

Hydraulic cylinders are widely used for heavy loads, but they require additional hydraulic stations, piping systems, and regular maintenance.

The LDC180 provides a cleaner electric alternative with:

• No hydraulic oil leakage risk

• Lower energy consumption during operation

• Programmable control of position, speed, and force

• Easier integration with PLC and industrial communication systems

• Reduced maintenance requirements

For modern factories pursuing automation upgrades and energy efficiency improvement, electric cylinders provide a more flexible and sustainable solution.
