The Roundline RT/57225/MC/250 saves 20% space compared with a basic ISO/VDMA length, enabling tighter machine layouts and higher product density in automated cells. This space efficiency translates to faster cycle times and reduced hardware footprint, which in turn lowers installation costs and increases line-side throughput. The cylinder features low-friction, long-life seals that reduce maintenance intervals and operational costs, while improving consistency across high-cycle applications. A standard magnetic piston enables full system versatility, allowing easy integration with position sensing and closed-loop control, which directly supports repeatability and traceability in precision handling tasks. The 25 mm bore with a 250 mm stroke delivers reliable linear motion for clamp-and-pick operations, while buffer cushioning minimizes impact and vibration, extending component life in demanding environments. Stainless steel barrel and stainless steel piston rod provide corrosion resistance, ensuring durability in moisture-laden or dusty factory floors, and facilitating compliance with cleaning routines common in food and packaging lines. Rc1/8 port sizing aligns with common pneumatic fittings, simplifying installation and maintenance. The operating range of 1 to 10 bar and -10 to 80 °C makes this cylinder suitable for a broad spectrum of production environments, from high-speed assembly to cleanroom-adjacent automation, while the Roundline family’s proven mounting compatibility reduces engineering time and risk when upgrading or expanding systems.

FAQs
Begin by confirming the Rc1/8 port fittings match your supply hardware, then align the cylinder with your mounting pattern, choosing an orientation that keeps the rod clear of obstructions. Use standard roundline mounting interfaces to simplify installation and ensure minimal side loads. Verify the magnetic piston is aligned with any sensors, and tighten end caps to spec to maintain cushion performance and prevent exhaust leakage.
Its 25 mm bore and 250 mm stroke provide a compact yet capable stroke profile for frequent actuations. The roundline design reduces overall footprint by about 20% versus basic ISO cylinders, enabling denser layouts. Low-friction, long-life seals minimize wear, while a standard magnetic piston supports sensor feedback for reliable position control in repetitive pick-and-place tasks.
Yes. The magnetic piston is designed for sensor integration, enabling straightforward position feedback to PLCs or motion controllers. This facilitates closed-loop control, improves repeatability, and supports traceability in quality-critical applications. When selecting sensors, ensure the sensor clearance matches the piston travel and mounting tolerances for accurate sensing across the 250 mm stroke.
The cylinder is designed for compressed air with operating temperatures from -10 to 80 °C and operating pressure from 1 to 10 bar (15 to 145 psi). The port size is Rc1/8, and the bore and stroke are 25 mm and 250 mm respectively. These parameters support a wide range of industrial environments while maintaining performance and reliability.
Leverage the cylinder’s low-friction, long-life seals to extend service intervals, reducing lubrication and part changes. Regularly inspect the magnetic piston for alignment and sensor engagement, and check end caps and cushioning to prevent excess impact. Use standard mounting hardware and verify that fittings, seals, and ports remain tight to maintain performance across high-cycle duty and varying environmental conditions.
