Norgren RM/91020/N2/25 Compact Cylinder - Magnetic
Part Number: RM/91020/N2/25
Quick Summary
Norgren RM/91020/N2/25 is a compact single-acting cylinder used for precise linear actuation in automation and packaging lines. Engineers often battle tight spaces and inconsistent force in compact actuators. In practice, CE compliance, IP-rated protection, and SIL-ready interfaces are important considerations for safe, regulator-friendly machinery. The design offers one-third the length of ISO/VDMA equivalents and features a magnetic piston, anodised aluminium barrel, and long-life seals, delivering space savings and durable performance for high-cycle environments.

Feature → Business Impact → Application: The RM/91020/N2/25 delivers a 20 mm bore with a 25 mm stroke, enabling a compact footprint that reduces fixture size and enables tighter layouts on small automation lines; this translates to lower assembly costs and faster line changes. The single-acting operation simplifies control logic and cycle timing, improving throughput in pick-and-place feeders and compact sorting stations. Feature → Magnetic piston → Application: The magnetized piston enables straightforward position sensing with non-contact sensors, simplifying automation integration and reducing wiring complexity in conveyor and packaging systems. Feature → Anodised aluminium barrel and stainless steel rod → Application: The corrosion-resistant housing and durable rod sustain performance in challenging environments with minimal maintenance in industrial environments. Feature → Operating range and porting → Application: A wide operating temperature (-5 to 80 °C) and 2–10 bar supply range support reliability across factory climates, while M5 porting ensures compatibility with standard compressed air fittings and rapid installation on existing manifolds. Feature → No cushioning → Application: Absence of internal cushioning minimizes parts count and potential maintenance, while control strategies with external damping or flow control can tailor impact for delicate assemblies in robotics and packaging lines. Feature → Compact RM/91000/M range compatibility → Application: This model integrates with common mounting patterns and spare parts across the RM/91000/M family, enabling streamlined replacements and scalable automation designs for multi-axis cells and line integrations.

FAQs
RM/91020/N2/25 uses a 20 mm bore with a 25 mm stroke and an M5 port, fitting standard ISO/VDMA mounting patterns and common bracket assemblies. It supports straightforward integration with existing manifolds and quick-change fittings, enabling rapid commissioning on small automation cells and packaging lines.
The cylinder operates from 2 to 10 bar (29 to 145 psi). Keeping supply pressure within this range ensures consistent force output and cycle timing, while preventing under- or over-pressurization that could affect repeatability and component life in high-cycle applications.
No, this model does not include internal cushioning. For delicate handling or high-speed applications, use external flow control or external cushioning solutions and appropriate mounting to manage impact and extend component life in robotic or packaging tasks.
Theoretical force is 161 N at the rated pressure. When selecting, compare the required load against this value, accounting for dynamic inertia and friction in your system. If required, a longer stroke or a higher force alternative from the RM/91000/M range may be considered to meet peak loads.
The barrel is made from anodised aluminium alloy and the piston rod from stainless steel (austenitic), with a magnetic piston for sensing. These choices deliver corrosion resistance, robust wear performance, and long service life in challenging factory environments, reducing maintenance intervals.
