Norgren RM/91040/M/50 Single Acting Cylinder - Magnetic Piston
Part Number: RM/91040/M/50
Quick Summary
Norgren RM/91040/M/50 single acting pneumatic cylinder provides compact linear actuation for automation and packaging applications. In tight assemblies, space constraints and wear from high-frequency cycles can slow line productivity. In many automation environments, CE marking, IP-rated protection, and SIL readiness are key considerations for pneumatic cylinders. Certification specifics should be verified with the supplier, but the model's corrosion resistance, magnetic sensing, and compact footprint support reliable operation across multiple installations and service intervals. The combination enables faster installation, improved uptime, and smoother integration with existing controls and sensor networks. Its compact dimension also reduces chassis size and material costs for OEMs.

Feature: Compact 40 mm bore with a 50 mm stroke reduces overall length, allowing tighter packaging and automation cells. Business Impact: The shorter footprint frees space for additional modules, minimizes pipe routing, and lowers enclosure size and weight in the assembly. Application: Ideal for small-line packaging, labeling stations, and compact robot end-effectors where space is at a premium. Feature: Low-friction, long-life seal design reduces wear and tear. Business Impact: Extends service intervals and reduces maintenance costs in high-cycle applications. Application: Suitable for continuous operation in conveyors and assembly lines with frequent cycling. Feature: Fully non-corrodible construction uses anodised aluminium barrel and stainless steel piston rod. Business Impact: Improves reliability in humid, washdown, or corrosive environments, lowering replacement costs. Application: Food & beverage, chemical, and outdoor machinery where exposure to moisture is common. Feature: Magnetic piston enables inline position sensing and easy integration with sensors. Business Impact: Simplifies feedback loops and reduces wiring complexity in automation systems. Application: Integrates with proximity switches and position sensors in control panels. Feature: Operating temperature -5 to 80 °C and operating pressure 2 to 10 bar with G1/8 port. Business Impact: Ensures compatibility with standard compressed-air systems and broad environmental conditions, reducing component mismatches. Application: General automation lines, conveyors, and fixture actuators that require robust pressure tolerance.

FAQs
The RM/91040/M/50 uses a standard 40 mm bore with a 50 mm stroke and G1/8 porting, enabling straightforward mounting on common support plates and end-plates. Ensure correct orientation for gravity-sensitive work and verify sensor placement if using the magnetic piston for position feedback. The compact length simplifies integration with limited chassis space and existing pneumatic manifolds.
Theoretical force is 687 N, suitable for mid-range actuation tasks. It operates at 2 to 10 bar and can tolerate temperatures from -5 to 80 °C, making it compatible with standard factory air lines and typical on-site environments. This combination supports reliable cycling in packaging, automation, and material-handling applications.
Yes. The RM/91040/M/50’s compact 40 mm bore and 50 mm stroke deliver space efficiency ideal for packaging and assembly cells. Magnetic sensing supports easy integration into control systems, while the corrosion-resistant construction improves uptime in busy production lines. It is well-suited for short-throw pick-and-place tasks and mounting into tight fixtures.
