Feature: 50 mm bore and 200 mm stroke create a compact yet powerful actuator. Business Impact: Delivers 1178 N theoretical force while saving 20% space versus basic ISO/VDMA cylinders, enabling tighter layouts and faster cycle times. Application: Ideal for precision pick-and-place and clamp applications on bottling lines or small-part assembly. Feature: Double-acting design powered by compressed air (medium: compressed air). Business Impact: Ensures repeatable, bidirectional motion with rapid response and interchangeable sequencing. Application: Suitable for high-speed closing/opening tasks and alignment operations in packaging and automation lines. Feature: Cushioning with buffer end-damping. Business Impact: Reduces impact loads, extends seal life, and minimizes vibration-induced wear, lowering maintenance costs over life. Application: Critical for delicate handling of parts or components with tight tolerances. Feature: Magnetic piston and stainless steel barrel/rod construction. Business Impact: Enables reliable position sensing and exceptional corrosion resistance in harsh environments, extending service intervals. Application: Sensor-ready actuation in factory automation, robotics, and end-of-line equipment. Feature: Rc1/4 port with compatible Pneufit C fittings and mounting options (foot, nut-style, and swivel mounts). Business Impact: Simplifies installation, reduces leak paths, and supports quick retrofits or expansions. Application: Configurations for compact machine frames and modular line setups across industries. Feature: Temperature and pressure range (−10 to 80 °C, 1 to 10 bar). Business Impact: Broadens usable environments while maintaining performance, contributing to predictable cycle quality. Application: Suitable for standard industrial air systems and temperature-controlled environments; aligns with typical maintenance windows and energy management practices. Industry context: The Roundline series emphasizes stainless components and long-life sealing to support continuous operation in automation environments, with mounting versatility that accommodates evolving line layouts and retrofit projects. Long-term ROI is enhanced through reduced downtime, faster changeovers, and lower total cost of ownership.

FAQs

The Roundline RT/57250/M/200 supports multiple mounting styles to fit compact spaces and high-speed cycles. Options include C-foot mounting (QM/57050/21) for fixed base alignment, nut-style N (M/P1501/90) for easy mounting, and piston-rod swivel or clevis mounts (QM/8040/38, QM/57040/25) to accommodate angular misalignment. These options align with typical ISO standards, minimize side loads, and simplify retrofits on existing lines.
The RT/57250/M/200 is engineered for high-cycle life thanks to its low-friction, long-life seals and a double-acting design that delivers consistent strokes. Buffer cushioning reduces impact, while a stainless steel barrel and piston rod resist wear in demanding environments. With a theoretical force of 1178 N, it maintains reliable motion across continuous cycles.
Yes, it features an Rc1/4 port and operates at 1–10 bar (15–145 psi) with an operating temperature range of -10 to 80 °C. This makes it compatible with standard compressed air systems and factory floor environments. Additionally, its magnetic piston enables straightforward integration with sensors for position feedback.
To maximize life and minimize maintenance, install with appropriate mounting options that minimize side loads, and use the factory-provided end caps and cushions. The buffer cushioning protects internal components from impact, while magnetic sensors facilitate preventive maintenance. Regularly verify port connections (Rc1/4) and use compatible Pneufit C fittings to prevent leaks and preserve cycling consistency.
