Norgren RM/92020/N4/50 Pneumatic Cylinder - Magnetic Piston
Part Number: RM/92020/N4/50
Quick Summary
RM/92020/N4/50 is a compact double-acting pneumatic cylinder used for precise linear actuation in automation and packaging applications. Engineers often struggle with bulky actuators that waste space or fail under harsh shop-floor conditions. This model delivers one-third the length of a standard ISO/VDMA cylinder while maintaining performance, aided by a magnetic piston and low-friction, long-life seals. It features fully non-corrodible construction and a robust operating range of -5 to 80 °C and 1 to 10 bar, making it suitable for varying line conditions. CE-like conformity and industry-standard interfaces support easy integration with existing control systems. Together, these characteristics reduce downtime, extend service intervals, and improve overall equipment effectiveness (OEE) in high-demand environments.

FAQs
This model uses a 20 mm bore with a standard M5 port, aligning with common ISO/VDMA mounting patterns. For installation, select end-attachments and brackets compatible with a double-acting, non-cushioned cylinder. Ensure the supply line supports 1–10 bar and use the magnetic piston for straightforward feedback integration. Typical installations favor compact frames and modular mounting to minimize cycle time and maximize space efficiency.
Key specs include 20 mm cylinder diameter, 50 mm stroke, and 188 N theoretical force. Operating pressure range is 1–10 bar with a temperature range of -5 to 80 °C. The cylinder is double-acting with no cushioning, uses a magnetic piston, and features a stainless steel piston rod with an anodised aluminium barrel for durability in industrial environments.
Yes, the combination of a low-friction, long-life seal design and a magnetic piston supports reliable position sensing and extended cycle life in high-throughput lines. The compact form factor reduces machine footprint, while the robust materials resist wear in busy packaging environments. If high-impact dampening is required, consider external cushioning or synchronised mechanical stops as a compatibility enhancement.
The provided data emphasizes non-corrodible materials, magnetic piston, and robust construction but does not specify explicit CE, IP, or SIL certifications. For applications requiring formal certifications, verify supplier documentation or request confirmation of applicable conformity marks and protective IP ratings for your specific installation and regional compliance requirements.
The long-life seals and stainless steel rod reduce wear and corrosion, lowering downtime and maintenance costs in continuous operation. The magnetic piston enables simpler feedback wiring and control integration, speeding setup and reducing commissioning time. Over a typical actuator lifetime in a busy line, these factors contribute to higher overall equipment effectiveness (OEE) and a faster payback cycle.
