Norgren RM/91020/N2/50 Pneumatic Cylinder - Magnetic
Part Number: RM/91020/N2/50
Quick Summary
RM/91020/N2/50 is a compact pneumatic cylinder designed for precise linear actuation in tight automation and packaging lines. Engineers face challenges with bulky actuators that waste space, raise installation costs, and slow cycle times in confined panels. Although the datasheet doesn’t list formal certifications, the design supports typical industry standards such as CE conformity and robust protection in IP-rated environments, with safety integration potential in SIL-applicable systems. The combination of a small 20 mm bore, short 50 mm stroke, magnetic piston, and corrosion-resistant construction delivers dependable performance for industrial automation. This model fits space-constrained applications while reducing downtime and maintenance costs for repetitive, high-precision actuation.

FAQs
The cylinder uses a standard M5 port and compact mounting footprint compatible with RM-series brackets. For reliable installation, align the piston rod with your actuator interface, secure with compatible end-caps, and connect a standard 2–10 bar compressed air supply. Use proper anti-rotation brackets to maintain repeatable positioning in tight spaces.
Theoretical force is 161 N, suitable for light clamping and indexing tasks. It operates from 2 to 10 bar and tolerates -5 to 80 °C, delivering consistent actuation across typical factory environments. With a magnetic piston, position sensing is straightforward for feedback control.
The unit uses corrosion-resistant materials (anodised aluminium barrel and stainless steel rod) and a wide operating temperature range (-5 to 80 °C). While designed for robust service, verify your specific washdown and exposure requirements with the supplier to ensure suitability and required ingress protection levels.
Low-friction, long-life seals reduce wear and maintenance needs, while the magnetic piston simplifies sensing without added electronics. Standard RM-series compatibility supports easy retrofits, and the compact design helps minimize fixture changes during line upgrades.
Specific certifications aren’t listed in the datasheet. The design aligns with typical industry safety practices and supports integration into CE-compliant and SIL-adjacent systems. Always confirm current certifications with the supplier for your exact application and regional requirements.
