Industrial High-Precision Hollow Shaft Electric Cylinder / Servo Actuator (Integrated Compact Design)
The LIND-WORLD industrial hollow shaft electric cylinder perfectly integrates cutting-edge servo drive technology with an innovative hollow mechanical architecture. Its unique center through-hole design allows complex cable harnesses, pneumatic tubes, laser beams, or coaxial rotary shafts to pass directly through the actuator's core.
This entirely eliminates the industry-wide pain point of external dangling cables wearing out or breaking during high-speed reciprocal movements, while dramatically simplifying spatial wiring layouts. Built with ground-grade screws and extended-life sealing systems, it guarantees exceptional stability and an ultra-long operational lifespan even in the harshest industrial automation environments.
Four Core Technological Advantages
Innovative Hollow Core Architecture: A continuous center through-hole (ID available from 15mm to 50mm) provides an internal pathway for pneumatics, slip rings, cabling, or optics, completely eliminating external tangling and mechanical interference.
Coaxial Integrated Compact Structure: The hollow rotor motor and cylinder body feature a coaxial integrated design, eliminating traditional couplings and motor mounts. This reduces the overall installation envelope by up to 30% compared to conventional actuators.
Micron-Level High Precision & Fast Response: Achieves a repeatability of up to ±0.01mm and supports high-speed dynamic responses up to 500mm/s across the full stroke, meeting the stringent requirements of precision manufacturing.
Industrial Durability & High Protection Rating: Utilizing heavy-duty aviation-grade aluminum alloy or stainless steel housing, combined with custom internal seals engineered for hollow routing, it offers up to IP65 protection, effectively blocking dust entry and preventing internal grease leakage.

Fast Logistics & Wear Parts Guarantee: Products are securely packed in heavy-duty, fumigation-free wooden cases compliant with international shipping standards. To minimize your machinery's downtime risk, we maintain a rolling inventory of core wear parts (e.g., seals, sliders) for immediate worldwide express dispatch via DHL/FedEx/UPS.
FAQ
Q: Can I pair the LIND-WORLD hollow shaft electric cylinder with my existing Siemens or Rockwell servo motors?
A: Yes, absolutely. We provide custom motor adapter flanges and inline couplings based on your motor's specific frame size, shaft diameter, and pilot diameter. Simply send us your motor's 2D drawing or brand model, and our engineers will handle the compatibility design.
Q: What is the maximum continuous duty cycle (ED rating) for your hollow shaft actuators?
A: For models equipped with premium ball screws, they support a 100% duty cycle under rated loads. For planetary roller screw configurations designed for extreme thrust, they can operate continuously under high-frequency conditions without degradation, provided the recommended lubrication intervals are maintained.
Q: How do you prevent internal grease from leaking into the hollow through-hole and damaging our optical cables or air lines?
A: LIND-WORLD utilizes a dual-lip rotary sealing system lined with specialized fluororubber (FKM) gaskets along the entire inner sleeve. This creates a completely isolated dry-channel for your cabling, ensuring that the heavy-duty grease remains restricted entirely to the screw and bearings.
