Norgren RM/92040/JM/20 Pneumatic Cylinder - Magnetic
Part Number: RM/92040/JM/20
Quick Summary
Norgren RM/92040/JM/20 is a compact double-acting pneumatic cylinder for precise linear actuation in automation applications. Engineers frequently struggle with long cycle times and seal wear under demanding service conditions. Standards guiding selection include CE marking and IP-rated configurations, while users demand reliable performance across -5 to 80 C and 1 to 10 bar. This model's magnetic piston and non-corrodible construction support robust sensing, system versatility, and reduced maintenance costs. With a compact form and long-life seals, it delivers consistent output and easier integration with existing control systems. The 40 mm bore and 20 mm stroke align with tight-spacing layouts, helping to reduce footprint and total cost of ownership.

One third the basic length of a corresponding ISO/VDMA model translates to tangible space savings. In practice, this means easier mounting in compact automation cells and packaging machines, improved cable routing, and less panel depth. It also reduces system weight and supports modular cabinet layouts. The result is faster line setup, easier machine retrofit, and lower integration risk. Low friction, long-life seals reduce wear and energy losses across high-cycle operation. The cylinder maintains consistent velocity and stroke over thousands of cycles, lowering maintenance costs and downtime. This is critical in packaging and assembly lines where uptime directly drives throughput. Fully non-corrodible construction helps in harsh environments, reducing corrosion-related failures and extending service life in humid or washdown conditions when combined with appropriate lubrication. Magnetic piston enables straightforward sensing and feedback with standard PLCs and sensors, enabling full control-system versatility. This eliminates the need for external switches in many applications while supporting simplified diagnostics and faster changeovers. Materials include an anodised aluminium barrel for lightweight rigidity and austenitic stainless steel piston rod for corrosion resistance. The 40 mm bore and 20 mm stroke pair with a G1/8 port and a -5 to 80 °C, 1 to 10 bar operating range to ensure compatibility with common air supplies and facility conditions. Cushioning is not included on this model, delivering a faster response and simpler construction. For demanding loads or precise damping, consider external cushions or a version with cushioning to tailor impact and longevity.

FAQs
RM/92040/JM/20 uses a G1/8 port and a compact 40 mm bore, designed to fit common mounting patterns and footprint reductions typical of compact automation cells. Its one-third length advantage eases installation in tight enclosures, simplifies cable routing, and reduces panel depth. Verify your mounting style and ensure adequate clearance at the stroke ends for reliable operation.
The cylinder provides a theoretical force of 754 N with a double-acting configuration, suitable for high-cycle tasks. Magnetic piston enables easy sensing, supporting PLC feedback without extra switches. Low-friction seals extend life and reduce energy consumption, while the no-cushion design delivers faster actuation. Plan for periodic inspection of seals after high-frequency cycles.
Yes, within its operating envelope of -5 to 80 °C and 1 to 10 bar (14 to 145 psi). This makes it compatible with many industrial environments and standard compressed-air systems. Ensure lubrication is appropriate for the temperature range and that the installed control system accommodates the magnetic piston for sensing in your layout.
The design emphasizes long-life seals and corrosion-resistant materials (anodised aluminium barrel, austenitic stainless steel piston rod). Expect reduced routine maintenance due to low wear, but schedule periodic checks of seals and rod integrity in high-cycle applications. If shocks or heavy loads are anticipated, consider external cushioning or selecting a model with built-in damping.
