Product Overview
The LIND-WORLD LHS Series High Precision Hollow Shaft Electric Cylinder represents the pinnacle of compact linear motion engineering. Specifically engineered to solve the industrial headache of cable wear, twisting, and friction in complex rotary-linear motions, this actuator integrates a rigid through-hole shaft with high-efficiency screw technology.
Manufactured strictly under the ISO9001:2015 Quality Management System and fully CE & RoHS certified, each unit provides global buyers with an eco-friendly, energy-saving, and zero-maintenance alternative to traditional pneumatic or hydraulic systems. With a theoretical service life exceeding 10,000 kilometers, we help automation engineers minimize machine footprints and lower the Total Cost of Ownership (TCO).
Premium Internal Components
We build trust by showing our global supply chain. No cheap parts, no cutting corners.
High-Precision Ball / Roller Screws: We strictly equip our cylinders with premium screws from world-renowned brands (such as HIWIN, PMI, or TBI) to guarantee an initial backlash controlled under 0.02 mm.
Imported Japan/Germany Bearings & Heavy Seals: Featuring high-rigidity angular contact ball bearings and premium NBR/Viton seals to achieve a standard IP54/IP65 protection rating, thoroughly sealing out industrial dust and cutting fluids.
Hard Anodized Aviation-Grade Housing: The outer shell is constructed from high-tensile extruded aluminum alloy with a hard-anodized coating, maximizing heat dissipation and mechanical wear resistance under continuous 24/7 operating cycles.

Industrial Applications
Multi-Axis Robotics & Center Joints: Routes internal wiring directly through the cylinder axis in articulated robot arms to prevent signal cable twisting.
Semiconductor Packaging & Wafer Handling: Delivers micron-level repeatable moves required for pick-and-place mechanisms and precision IC chip alignment.
Optical & Laser Processing Equipment: Seamlessly accommodates fiber optic routings and laser paths right through the inner bore for stable laser cutting and welding.
Automated Rotary Indexing Tables: Acts as a heavy vertical or horizontal pusher while allowing center pneumatic lines to supply automated clamps simultaneously.
Quality Control & Reliable Factory Verification
100% Full Laser Interferometer Calibration: Every single high-precision cylinder is individually tested with Renishaw laser interferometers. An independent Factory Accuracy Inspection Report is provided with every shipment.
Full Load Dynamometer Durability Test: Prior to dispatch, each actuator runs under a 100% simulated load bench test for noise, temperature rise, and rated thrust output to eliminate mechanical flaws.
Global Logistics & Buyer Guarantees
Vacuum Sealing + Heavy Export Wooden Cases: Packaged with heavy VCI anti-rust vacuum bags and enclosed in non-fumigation solid plywood boxes with inner high-density EVA shock-absorbing foams.
Flexible Delivery Terms (FOB, CIF, DDP): We offer flexible options. Our mature freight network supports DDP (Delivered Duty Paid) shipping directly to your factory door across Europe and North America-we handle all customs and duties for you.
12-Month Comprehensive Warranty: We provide a full 1-year product warranty along with immediate free replacement parts for non-human wear, supplemented by lifetime remote engineering support via Zoom/Teams.
FAQ
Q: Can you customize the inner hole size if my slip ring or laser beam requires a specific diameter?
A: Yes, we offer absolute customization flexibility. While our standard off-the-shelf inner diameters are Ø15 mm, Ø25 mm, Ø40 mm, Ø50 mm, and Ø60 mm, we can machine custom hollow shafts tailored to your exact clearance needs. Our R&D team can design and issue custom 3D drawings within 48 hours for your approval.
Q: How do we interface our existing Siemens, Rockwell, or Allen-Bradley servo motors with your cylinder?
A: Installation is 100% plug-and-play. During your inquiry, simply provide us with your motor's part number or datasheet (including flange diameter, shaft diameter, and pilot diameter). We will custom-machine the motor adapter housing and keyless coupling to perfectly match your motor at zero extra cost.
Q: What type of lubrication is required for the hollow shaft series, and how often?
A: Our cylinders come pre-lubricated with high-performance lithium-based grease suitable for standard industrial environments. For regular maintenance, we design accessible grease nipples onto the cylinder body. Under normal 24/7 operating conditions, we recommend re-greasing every 3 to 6 months or every 500 kilometers of travel.
Q: Can this hollow shaft cylinder be mounted vertically, and does it support a brake?
A: Yes, it supports vertical, horizontal, and inverted installations. For vertical applications, we highly recommend selecting a servo motor equipped with an electromagnetic holding brake to prevent the cylinder shaft from back-driving or dropping during sudden power outages.
Q: What is the standard lead time for sample prototypes versus bulk B2B orders?
A: For standard configurations, sample prototypes can be manufactured and dispatched within 7 to 10 working days. For bulk B2B orders or highly customized projects (special strokes, custom inner diameters, or IP65 upgrades), the typical lead time is 3 to 4 weeks.
Q: Do you provide the 3D CAD files before we place an official purchase order?
A: Absolutely. We understand that design engineers need to simulate space constraints in their master assemblies. Once we confirm your technical requirements (stroke, thrust, and motor model), our engineering department will provide free 3D CAD models in .STEP or .IGS formats.
