Custom Long Stroke Electric Cylinders (Heavy Duty & High Precision)
Engineered up to 3500mm Stroke and 500kN Load Capacity. Designed as a clean, maintenance-free, and high-rigidity alternative to hydraulic systems in harsh industrial environments.
ISO9001:2015 Certified | CE & RoHS Compliant | 100% Factory Full-Stroke Load Tested
Engineered for Zero-Deflection & High Rigidity
Operating at extended strokes exposes linear actuators to high risks of buckling, bending, and premature wear. Our custom long-stroke electric cylinders feature specialized structural enhancements to ensure lifespan and structural integrity under heavy industrial duty cycles.
Anti-Buckling & Multi-Point Internal Guidance: Utilizes high-strength alloy steel with surface induction hardening (HRC 58-62). Integrated with wide-span internal guiding rings to eliminate rod deflection and ensure ultra-smooth linearity at full 3.5-meter extension.
Advanced Sealing & Environmental Protection: Equipped with multi-stage polyurethane seals and heavy-duty scrapers rated up to IP67 to prevent dust, water, and abrasive metallic debris from contaminating the internal ball or roller screws.
Optimized Total Cost of Ownership (TCO): Built-in centralized lubrication ports allow for seamless maintenance without dismantling the machinery. Reduces energy consumption by up to 60% compared to equivalent hydraulic power units (HPUs).
Zero-Backlash Precision Control: High-precision ground ball screws (C5/C3 grade) or planetary roller screws ensure repetitive positioning accuracy up to plus or minus 0.01mm, even under sustained heavy axial loads.

Quality Assurance & Testing Protocol
100% Full-Stroke Dynamometer Testing: Every custom cylinder undergoes continuous full-load, full-stroke cycling tests on our automated test beds. Speed profiles, temperature rises, and torque ripple are recorded to verify operational integrity before dispatch.
Laser Interferometer Accuracy Calibration: Lead accuracy and repetitive positioning error are verified using Renishaw laser interferometers. A comprehensive testing report and calibration certificate are included in the standard shipping documentation.
Seaworthy Reinforced Packaging: Long-stroke cylinders are highly vulnerable to bending and structural deflection during transit. We utilize customized, rigid, vacuum-sealed wooden crates with multi-point anti-vibration structural supports to guarantee zero geometric deformation upon arrival.

FAQ
Q: How do you solve the vibration and noise issue of the ball screw when the stroke exceeds 2000mm?
A: For super long strokes, the screw shaft can sag under its own weight, causing resonance, noise, and premature wear at high speeds. We deploy intermediate travelling screw support mechanisms that slide internally within the cylinder profile. This provides continuous axial support to the screw, drastically reducing resonance and allowing high-speed operations without sacrificing precision.
Q: Can you deliver custom cylinders that match our existing European-standard mounts?
A: Absolutely. We can customize the front/rear clevis, rod end threads, and trunnion dimensions to match ISO 15552 or DIN standards perfectly. This allows a 1:1 direct drop-in replacement for your current European hydraulic or pneumatic cylinders, eliminating the need to modify your existing mechanical frameworks.
Q: Do you offer digital twins or 3D models for our engineering team to run interference checks?
A: Yes. Once the initial technical parameters are frozen, our R&D department will generate the exact 3D STEP / CAD files of the customized actuator. This allows your engineering team to import the cylinder into your master assembly file to verify space clearances and structural integration before we begin manufacturing.
