ISO 15552 and VDMA compatibility ensure seamless interchangeability with existing cylinders, reducing downtime during retrofits and new line installations. This standard alignment translates into faster sourcing, simplified spares management, and lower engineering risk when integrating with current control systems. Application: OEM machines and automation cells benefit from plug-and-play fit with minimal modification. The 250 mm cylinder diameter delivers a high theoretical force of 29436 N, enabling reliable clamping, lifting, and pushing operations in demanding packaging and material handling tasks, while maintaining smooth cycling under typical plant air pressures. Double acting with adjustable cushioning provides precise deceleration and reduced impact at end-of-stroke, extending seal life and minimizing vibration. The magnetic piston rod supports reliable sensor feedback and easier position sensing, improving control accuracy. Rugged aluminium barrel and corrosion-resistant construction simplify maintenance and extend service intervals. Broad operating temperature and pressure ranges, combined with versatile mounting options, reduce design constraints and promote scalable deployment across multiple lines.

FAQs
For installation on ISO 15552 platforms, ensure compatibility with standard tie-rod mounting patterns and adaptor kit availability. Check your end-of-stroke cushioning setting and align the bore axis to minimize side loading. Use appropriate mounting brackets and block supports to prevent misalignment, and verify port orientation to simplify plumbing. The cylinder’s modular design supports multiple mounting configurations, reducing retrofit effort and commissioning time.
This cylinder operates from 1 to 16 bar and withstands temperatures from -20 to 80 °C (-4 to 176 °F), enabling stable performance in harsh environments. With a theoretical force of 29436 N, it sustains heavy push/pull tasks, while adjustable cushioning mitigates impact during high-speed cycles. For best results, ensure consistent air supply quality and monitor lubrication to maintain actuator efficiency over time.
Yes. Its 250 mm bore, 50 mm stroke, and high actuation force make it well suited for clamping, position holding, and rapid transfer operations in packaging, material handling, and assembly lines. The magnetic piston rod facilitates reliable sensing for closed-loop control, while the adjustable cushioning protects tooling and substrates from shock, extending component life and reducing maintenance intervals.
The cylinder conforms to ISO 15552 and ISO 6431 standards, and aligns with VDMA 24562 and NFE 49-003-1 guidelines. This combination ensures interchangeability with standard components, validated ruggedness for industrial use, and compatibility with common automation controls, sensors, and safety systems across Europe and beyond.
Expected benefits include reduced downtime due to standardized ISO interfaces, longer life from adjustable cushioning and corrosion-resistant construction, and easier sensor integration for improved control accuracy. The combination of robust materials and modular mounting supports lower maintenance costs and accelerated PLC integration, delivering favorable total cost of ownership over typical automation project lifecycles.
