Norgren RT/57225/MF/200 Roundline Cylinder - Magnetic
Part Number: RT/57225/MF/200
Quick Summary
RT/57225/MF/200 Roundline cylinder provides compact double-acting actuation for tight-spaced automation lines. Facing space constraints and frequent seal wear, many customers struggle to fit reliable cylinders into small footprints. This model helps by delivering a 25 mm bore and 200 mm stroke in a shorter envelope, reducing machine length by about 20% compared with a basic ISO/VDMA cylinder. Engineered for durability, it uses a stainless steel barrel and a stainless steel piston rod with long-life seals and buffer cushioning to extend cycle life. The standard magnetic piston enables full control system versatility with sensors and feedback. Engineers also consider CE safety compliance, IP-rated protection, and SIL-compatible control concepts when selecting compact pneumatic actuators. Together, the combination of compatibility for Rc1/8 ports and a 1–10 bar supply supports flexible installation. It is well suited for packaging, pick-and-place, and automation tasks.

FAQs
RT/57225/MF/200 Roundline cylinder uses standard Rc1/8 ports and offers common mounting options such as feet, flange, or clevis configurations. This enables straightforward integration with existing manifolds and frames. When selecting mounting, consider stroke compatibility (200 mm), bore size (25 mm), and available space to maintain alignment and prevent binding during repetitive cycles.
The RT/57225/MF/200 provides a theoretical force of 294 N at the specified operating conditions. It is designed for an operating pressure range of 1 to 10 bar. Temperature tolerance spans -10 to 80 °C, allowing use across typical industrial environments while maintaining positioning accuracy and repeatability.
Yes, its 25 mm bore and 200 mm stroke, combined with a magnetic piston and buffer cushioning, make it well suited for packaging and pick-and-place activities. The compact Roundline geometry helps fit into tight spaces, while sensor-ready magnetic actuation supports reliable feedback for precise placement and cycle timing in automated packaging systems.
Engineers typically verify CE safety compliance, appropriate IP protection levels for the environment, and SIL-compatible control integration for pneumatic actuators. While this model is designed to align with standard industry practices, always consult the official datasheet and your internal safety requirements to confirm the exact certifications applicable to your installation.
The stainless steel barrel and rod, paired with long-life seals and buffer cushioning, reduce wear and extend service life, lowering maintenance frequency. Magnetic sensing facilitates easier diagnostics and predictive maintenance. In practice, users report lower replacement intervals and improved uptime in space-constrained lines, contributing to a favorable return on investment when deployed across multiple positions in packaging and automation tasks.
