FAQs
For installation, align the cylinder along the intended axis with the Rc1/8 port oriented to match your supply line. Use proper mounting brackets compatible with Roundline cylinders and verify piston travel does not collide with adjacent hardware. The magnetic piston supports easy sensing, while buffer cushioning minimizes impact at end-of-stroke, reducing mechanical stress on fixtures and parts.
The cylinder operates from -10 to 80 °C (14 to 176 °F) and supports 1 to 10 bar (15 to 145 psi). Ensure your compressed air supply is clean and dry to maintain seal life and consistent performance across the full temperature and pressure range.
Yes. The combination of low-friction, long-life seals, and magnetic piston design supports high-cycle operation with reduced maintenance. The 25 mm bore and 320 mm stroke offer a compact yet capable actuation profile ideal for repetitive pick-and-place and transfer tasks in densely packed automation lines.
Regular inspection of end caps and seals is advised, with attention to any wear on the piston rod and the integrity of the buffer cushioning. The magnetic piston simplifies retrofitting sensors for condition monitoring. Because of stainless steel components, corrosion resistance is strong, but maintain clean, dry air to maximize seal life and performance.
Roundline cylinders like RT/57225/MF/320 are designed to optimize length for a given stroke, delivering roughly 20% space savings versus basic ISO/VDMA cylinder lengths. This enables tighter machine layouts, more compact enclosures, and opportunities for additional automation peripherals without expanding overall footprint.
