Norgren RM/92040/JM/80 Cylinder - 40 mm Dia x 80 mm Stroke, Magnetic Piston, One-Third Length
Part Number: RM/92040/JM/80
Quick Summary
RM/92040/JM/80 is a compact pneumatic cylinder designed for precise linear actuation in automation cells. Engineers often wrestle with cramped spaces and the challenge of upgrading from longer ISO/VDMA models. Typical certifications you’ll encounter in the field include CE compliance for machinery safety, IP-rated protection for harsh environments, and SIL-rated variants in compatible configurations. The magnetic piston and corrosion-resistant construction deliver reliable, high-cycle performance in demanding lines, while the compact footprint simplifies retrofits and maintenance planning. This combination helps modernize systems with minimal rework, supporting higher throughput and lower overall operating costs.

A standout feature is the one-third length compared with ISO/VDMA models. This reduction in footprint translates into easier mounting and more flexible line layouts, especially in tight packaging and robotic pick-and-place cells. The magnetic piston enables seamless sensing and straightforward integration with control systems, reducing wiring complexity and enabling robust position feedback in automation conveyors. The barrel is made from anodised aluminium alloy with a stainless steel austenitic piston rod, delivering excellent corrosion resistance and long service life in demanding factory environments. With no internal cushioning, the design supports fast cycling and precise positioning, while the 40 mm bore and 80 mm stroke balance compactness with meaningful stroke. Operating pressures from 1 to 10 bar and temperatures from -5 to 80 °C ensure compatibility with common plant air and ambient conditions. Theoretical force of 754 N provides clear performance guidance for mid-range actuations, and compatibility with the RM/92000/M family simplifies part interchange and spares strategy.

FAQs
When deploying RM/92040/JM/80, ensure the mounting area accommodates the 40 mm bore and 80 mm stroke without obstructing operator access. Use standard G1/8 fittings for air supply and verify alignment with the piston rod to prevent side loads. Maintain clean, dry compressed air within a 1 to 10 bar range and avoid exposure to excessive heat beyond -5 to 80 °C. Consider a compact manifold or sandwich mount to minimize tube routing and maximize accessibility for maintenance.
The RM/92040/JM/80 has a listed theoretical force of 754 N. Actual force during operation depends on supply pressure within the 1–10 bar range and operating conditions. For design planning, use 754 N as a reference point at nominal conditions, and adjust for real-world friction, temperature, and load direction. Always validate with your application’s dynamic profile to ensure consistent performance.
The cylinder uses an anodised aluminium barrel and a stainless steel piston rod, delivering corrosion resistance suitable for many industrial environments. While these materials improve durability, consult the datasheet for exact IP ratings and environmental specifications to confirm suitability for your application. In general, this model is designed for robust performance on standard production floors and in demanding line environments with proper servicing.
The magnetic piston provides easy, non-contact position sensing compatibility, enabling straightforward integration with sensors and control logic. This reduces wiring complexity and simplifies closed-loop control in automation cells. With standard 40 mm bore and 80 mm stroke, the device suits many standard valve manifolds and sensor arrays, improving repeatability and reducing commissioning time in robotic pick-and-place and packaging lines.
