Norgren RM/92040/JM/40 Pneumatic Cylinder - Magnetic Piston
Part Number: RM/92040/JM/40
Quick Summary
Norgren RM/92040/JM/40 Pneumatic Cylinder is a compact double-acting actuator designed for precise, space-saving linear motion in automation projects. Engineers often battle bulky envelopes and frequent maintenance when using standard ISO/VDMA cylinders in tight layouts. The data shows it delivers one-third the basic length of a comparable model, with low-friction, long-life seals and a fully non-corrodible body, enhancing reliability. The magnetic piston enables sensing and seamless integration with modern control systems. While explicit certification details aren’t provided in the data, the unit’s rugged materials and operating range support robust performance across typical factory environments. Together with a 1–10 bar operating window and a -5 to 80 °C range, this cylinder can reduce downtime and simplify multi-axis installations, while remaining compatible with common manifolds and controllers.

The RM/92040/JM/40 is designed to maximize space efficiency without sacrificing performance. Its compact form, delivering roughly one-third the length of a comparable ISO/VDMA model, reduces machine footprint and simplifies installation in tight automation cells. This directly translates to higher system density and lower capital cost per axis, especially in packaging and small-assembly lines. The low-friction, long-life seals minimize wear and maintenance cycles, driving up overall equipment effectiveness (OEE) and reducing spare-parts consumption. A fully non-corrodible construction protects against moisture and corrosive environments, extending service intervals and lowering lifecycle costs. The standard magnetic piston enables reliable sensing with conventional controllers, improving interlock capability and simplifying integration with existing control architectures. Built to withstand -5 to 80 °C and 1–10 bar pressures, the cylinder supports stable operation across a wide range of plant conditions while maintaining precise repeatability. The anodised aluminium barrel and Austenitic stainless-steel piston rod deliver durability and predictable performance, even in high-cycle applications. The RM/92040/JM/40 is compatible with common mounting patterns and manifolds, enabling straightforward retrofit or expansion without complex rework. A lack of internal cushioning means external damping or mechanical stops can be added to tailor impact characteristics for sensitive loads, helping you balance speed, force, and liftoff in a single package. Range RM/92000/M positioning confirms its place within the broader Norgren RM family for scalable automation.

FAQs
For installation, verify mounting compatibility with standard 40 mm bore cylinders and ensure G1/8 port fittings are used for clean, leak-free connections. Align the actuator with the load path to minimize side loads, and consider external cushioning alternatives since this model ships without internal damping. The magnetic piston supports easy sensing, so integrate with existing sensors and controllers for straightforward automation.
The cylinder delivers stable performance across a 1–10 bar operating range and a -5 to 80 °C temperature spectrum, with a 754 N theoretical force rating. Its low-friction, long-life seals reduce wear in high-cycle applications, lowering maintenance and replacement costs. Magnetic sensing further simplifies control integration, supporting reliable operation in continuous production environments.
Yes, the design emphasizes a fully non-corrodible construction and an anodised aluminium barrel, which resist moisture and corrosion better than basic alloys. The stainless-steel piston rod adds additional durability. While explicit IP or CE certifications aren’t listed in the data, these material choices align with general industry expectations for rugged, long-life pneumatic actuation in challenging environments.
The cylinder uses a magnetic piston, enabling straightforward integration with standard proximity and magnetic sensors, as well as existing PLC or servo-based control architectures. This sensing capability supports reliable position feedback and easier implementation of interlocks, sequencing, and force-control strategies across packaging, pick-and-place, and small-assembly lines.
The model is designed with a significantly shorter envelope—about one-third the basic length of a typical ISO/VDMA cylinder—providing a smaller installation footprint. This makes it particularly advantageous in compact automation cells where space is at a premium, enabling closer mounting to other actuators and controls while maintaining full stroke and force capabilities.
