Norgren RM/92050/N4/10 Pneumatic Cylinder - Magnetic Piston
Part Number: RM/92050/N4/10
Quick Summary
Norgren RM/92050/N4/10 Pneumatic Cylinder provides 50 mm bore and 10 mm stroke for compact linear actuation in automation lines. Engineers often wrestle with space constraints and frequent maintenance when integrating cylinders into high-speed lines. In practice, CE compliance, SIL risk considerations, and IP-rated protection are common benchmarks to verify during procurement. This compact cylinder, with a magnetic piston and low-friction seals, helps reduce downtime and total cost of ownership. Designed for reliable operation from -5 to 80 °C and 1 to 10 bar, it supports demanding applications in packaging, machine tending, and pick-and-place tasks, while the anodised aluminium barrel and stainless steel rod resist wear.

The RM/92050/N4/10 combines a compact form factor with a generous 50 mm bore and a 10 mm stroke, delivering substantial thrust in a fraction of the space required by traditional ISO/VDMA models. This space-saving design translates directly to shorter machine footprints, easier retrofits, and faster cycle times on small-footprint automation cells. In practice, engineers can mount multiple actuators on tight conveyors or robotic grippers without compromising reach or repeatability, enabling higher line throughput and reduced capital cost per cycle. The cylinder’s short length also simplifies routing and enclosure design, minimizing enclosure cost and improving maintenance access to other critical components on the line.

FAQs
Mounting RM/92050/N4/10 requires precise axial alignment and secure end mounting. Use appropriate brackets or fixtures to maintain concentric piston travel and minimize side loads that could increase wear. The G1/8 port sizing is standard for many control valves, so pair with compatible solenoid or pilot-operated valves. Ensure clean, dry air supply and verify seal integrity to sustain repeatable performance in demanding cycles.
Yes, within its 1–10 bar operating range the cylinder delivers reliable thrust for fast actuations, aided by the low-friction seal design and magnetic piston for clean feedback signals. To optimize performance, match the supply pressure to the required force, use flow control to manage acceleration and deceleration, and avoid cushioning since this model has no built-in end-of-stroke damping. Proper alignment minimizes inertia and improves cycle life.
The actuator uses an anodised aluminium barrel and a martensitic stainless steel piston rod, offering enhanced corrosion resistance and durability in many industrial settings. While this improves lifespan in humid environments, ensure clean, dry compressed air and appropriate lubrication practices. For persistent exposure to corrosive media, evaluate additional protection strategies or enclosure options to maintain performance.
The device employs a long-life, low-friction seal design to extend service intervals and reduce maintenance costs. Regular air quality checks, moisture removal, and periodic inspection of mounting hardware help sustain seal performance and prevent leaks. The magnetic piston enables straightforward position sensing, simplifying non-destructive wear monitoring and reducing unplanned downtime through proactive maintenance planning.
