Norgren RM/92040/M/125 Compact Cylinder - Magnetic Piston
Part Number: RM/92040/M/125
Quick Summary
RM/92040/M/125 is a compact double-acting cylinder designed for precise pneumatic actuation in automation lines. In fast-paced manufacturing, space constraints and routine maintenance drive up downtime and total cost of ownership, so a streamlined actuator that fits tight envelopes is essential. This model leverages a fully non-corrodible specification and low-friction, long-life seals to reduce wear and lubrication needs, while a standard magnetic piston enables straightforward sensing and control integration. With CE-compliant design and compatibility with SIL-rated control schemes, it meets safety and performance expectations. Industry users appreciate the combination of compact geometry and robust materials, which translates into higher machine uptime and predictable cycle times for robotic pick-and-place and material handling tasks.

FAQs
RM/92040/M/125 is designed with common pneumatic mounting conventions in mind, including a 40 mm diameter and 125 mm stroke that align with standard cylinder interfaces. The G1/8 port and magnetic piston facilitate straightforward sensor integration. Always verify specific mounting dimensions against your machine’s ISO/VDMA patterns and refer to the datasheet for accessory compatibility and torque ratings.
The cylinder operates from 1 to 10 bar and tolerates temperatures from −5 to 80 °C (23 to 176 °F). This broad range supports diverse environments, from standard factory floors to more demanding automation cells. Ensure your compressed air quality meets your system’s requirements, and consider ancillary protection if exposure to extreme conditions is likely.
The RM/92040/M/125 delivers a theoretical force of 754 N at 40 mm diameter. Use this figure as a baseline for mid-load actuation calculations, accounting for dynamic factors such as load inertia, ambient temperature, and duty cycle. For higher loads, consider a larger bore or longer stroke, and validate with a practical test under your real operating conditions.
The magnetic piston enables straightforward sensing integration, enabling standard magnetic switches or reed sensors to monitor piston position. This simplifies control loop feedback, reduces wiring complexity, and improves reliability in automation applications. When designing your system, confirm sensor compatibility with your PLC or safety controller and account for sensor placement tolerances.
This model excels in compact automation environments requiring reliable linear actuation, such as robotic pick-and-place, fixture clamping, and material handling on small to mid-size production lines. Its space-saving footprint, corrosion-resistant materials, and magnetic sensing make it a strong fit for high-cycle operations where uptime and repeatable motion are critical.
