Quick Summary

Roundline cylinder RT/57250/M/320 provides compact, double-acting pneumatic actuation for precise linear motion in automation cells. Engineers often face space constraints and retrofit challenges when upgrading ISO cylinders, making a shorter, space-saving solution highly desirable. While the datasheet highlights a magnetic piston, stainless steel components and buffer cushioning, please verify any required certifications in your region via the official datasheet. This model also delivers strong compatibility with standard Pneufit C fittings and mounting options, supporting seamless integration into existing lines and reducing changeover time for higher uptime.

The 50 mm bore Roundline cylinder delivers space savings up to 20% versus a basic ISO/VDMA cylinder, enabling more compact layouts in crowded automation cells and packaging lines. The double-acting design provides reliable, repeatable push-pull motion, improving cycle consistency and throughput. A magnetic piston supports easy sensor integration for position feedback, reducing wiring complexity and enabling straightforward control with standard reed switches. The stainless steel barrel and piston rod offer corrosion resistance and long life in demanding environments, while low-friction seals extend service intervals and cut maintenance costs. Buffer cushioning minimizes impact and vibration during end-of-stroke operations, protecting delicate components and extending actuator life. Present port size Rc1/4 and 1–10 bar operating pressure support robust performance across typical plant air systems. The combination of a standard mounting footprint and multiple compatible fittings ensures fast installation and scalable configurations, addressing common objections about retrofits and compatibility with existing control architectures. In real-world use, the RT/57250/M/320 is well-suited for pick-and-place, push-to-fit, and material handling tasks where space is at a premium and reliability is non-negotiable.
