Introduction
LIND LDC180 Direct-Connect Heavy-Duty Servo Electric Cylinder (Iron Barrel)
【Heavy-duty flagship: 50-ton precision thrust + anti-rotation positioning dual protection】
Product Overview
The Lind LDC180 series is a high-thrust servo electric cylinder designed for ultra-heavy industrial applications. It adopts a large-diameter 217mm thickened iron cylinder barrel, which is robust and extremely rigid. The maximum thrust load is up to 50 tons (500kN). The built-in anti-rotation rod ensures smooth operation, and the proximity switch enables precise positioning. It can perfectly replace traditional hydraulic cylinders and provide a cleaner, more efficient, precise and safer linear power solution.
Core parameters and structural advantages
Cylinder block material:
High-strength precision cast iron cylinder barrel, outer diameter φ217mm, heavy-duty integrated structure, excellent resistance to bending, torsion and impact, and no deformation under long-term heavy load.
Thrust:
Rated/maximum thrust of 50 tons (500,000N), meeting the requirements of extreme load conditions such as heavy press fitting, lifting, extrusion, and forging.
Transmission Core:
Built-in heavy-duty planetary roller screw / large lead ball screw (optional), combined with high-precision heavy-duty bearing assembly, resulting in high efficiency, long service life, low noise, and no crawling.
Anti-rotation and positioning configuration:
The built-in anti-rotation rod effectively prevents the piston rod from rotating, ensuring precise and error-free execution of actions, making it suitable for heavy-duty scenarios with high requirements for angle accuracy. Equipped with a proximity switch, it can achieve precise positioning and limit reminders of the piston rod stroke, improving the safety and automation of equipment operation and facilitating linkage with the control system.
Control Precision:
Servo closed-loop control with repeatability of ±0.01mm and thrust control accuracy of ≤1%. Position, speed and thrust are all programmable and adjustable in closed loop. Proximity switches further improve positioning accuracy.
Protection level:
With IP65 high protection, it is dustproof and splashproof, suitable for harsh environments such as workshops, metallurgy, construction machinery, and outdoors. The anti-rotation rod and proximity switch are both sealed to ensure long-term stable operation.
Installation and adaptation:
It supports various installation methods such as front flange, rear flange, trunnion, and joint, and is easy to integrate into presses, metallurgical equipment, test benches, and automated production lines. The anti-rotation rod and proximity switch can be flexibly adapted according to installation requirements.
Product Highlights
50T pure electric heavy-duty:
Say goodbye to hydraulic stations, no leaks, no pollution, energy consumption is reduced by 40%+ compared to hydraulic systems, faster response, more stable control, and simpler maintenance.
Large diameter iron cylinder rigidity:
φ217mm thickened steel cylinder, load capacity several times higher than aluminum alloy cylinders. Excellent stability in long-stroke and eccentric load conditions, eliminating vibration and deformation.
Anti-spinning + positioning dual protection:
The built-in anti-rotation rod eliminates piston rod rotation deviation, and the proximity switch enables precise limit and positioning. This dual configuration significantly improves the equipment's operating accuracy and safety, and reduces the cost of manual intervention.
High precision + long lifespan:
Key components have undergone millions of fatigue tests. Combined with a forced lubrication system, they operate stably and reliably under continuous heavy loads, with a lifespan far exceeding that of traditional hydraulic actuators. The anti-rotation rod and proximity switch are made of high-quality parts, making them suitable for long-term use under heavy load conditions.
Intelligent electronic control compatibility:
It supports PLC and bus communication (Profinet / EtherCAT / Modbus), can be connected to the Industrial Internet of Things, and proximity switch signals can be directly linked to the control system to realize remote monitoring, multi-cylinder synchronization, and force-position closed-loop control.

Why Ball Screw Instead of Lead Screw?
The transmission system directly affects efficiency, accuracy, and service life.
The LDC180 supports precision ball screw and planetary roller screw solutions to meet different heavy-duty requirements.
• Higher Mechanical Efficiency
Ball screw transmission reduces friction through rolling contact.
Compared with traditional lead screw systems, it provides:
①Higher transmission efficiency
②Lower energy loss
③Reduced heat generation
• Better Positioning Accuracy
Lower friction and improved transmission precision help maintain stable positioning performance.
This is especially important for:
①Heavy press applications
②Precision testing equipment
③Automated assembly systems
• Longer Operating Life
Reduced friction minimizes mechanical wear.
Combined with heavy-duty bearings and lubrication systems, the actuator maintains reliable performance during long-term operation.
Why Direct-Drive Structure?
The LDC180 adopts a direct-connect transmission design between motor and actuator mechanism.
• Higher Rigidity
The direct connection reduces unnecessary transmission components.
This improves structural rigidity and minimizes mechanical clearance.
• Faster Response
The simplified transmission path improves:
①Acceleration response
②Motion synchronization
③Control accuracy
Suitable for automated systems requiring fast and precise movement.
• Reduced Maintenance Points
Fewer mechanical transmission parts reduce potential failure sources and simplify maintenance.
Why Anti-Rotation Structure Matters?
Heavy-duty applications require not only high force but also stable movement control.
The LDC180 integrates an anti-rotation rod structure to improve actuator reliability.
• Prevents Rod Rotation
The anti-rotation mechanism maintains piston rod alignment during operation.
This improves:
①Angular accuracy
②Load stability
③Equipment reliability
• Supports Precision Automation
Combined with proximity switches, the structure enables accurate positioning and safe machine operation.
