IMI Norgren RM/92020/M Double Acting Cylinder - 40mm Stroke
Part Number: RM/92020/M/40
Quick Summary
Norgren RM/92020/M pneumatic cylinder delivers compact double-acting actuation for precision automation and part handling. In tight machine footprints, engineers face space constraints, frequent misalignment, and wear that erodes cycle times and throughput. CE conformity supports European deployments, while a magnetic piston and fully non-corrodible barrel extend sensing options and service life. With a 20 mm bore, 40 mm stroke, and an operating range of 1 to 10 bar, the unit delivers robust force in a smaller envelope. Its standard mounting provisions and M5 port fittings simplify installation and retrofit, reducing downtime and total cost of ownership across industrial automation lines.

FAQs
Use the M5 port with Pneufit C adapters (C02250405 or C02470405) for a secure, push-in connection. Choose mounts from the range such as C - Foot Mounting 20mm bore, BG - Front/Rear Flange, or clevis styles to position the cylinder for optimal alignment. For sensing, attach a compatible magnetic switch bracket (M/P72487B) and M/50 LSU switch if needed. Verify air supply at 1–10 bar and confirm no kinks or leaks in tubing PA2 lines.
The RM/92020/M provides a theoretical force of 188 N at the given bore and stroke. With a 1–10 bar operating pressure, you can achieve reliable actuation for typical 20 mm bore applications. Speed depends on load and supply pressure; use a light-to-moderate load to maximize cycle times. Ensure the medium is clean, dry compressed air to maintain seal life.
Yes. Its 20 mm bore and 40 mm stroke deliver compact, repeatable actuation ideal for pick-and-place, clamping, and fixture operations in small-form automation. The magnetic piston supports straightforward sensing for position feedback, and the compact length helps integrate multiple cylinders in tight robotic or conveyor setups. Ensure mounting provides proper alignment to avoid side load effects.
The RM/92020/M is designed for European markets with CE conformity in mind, and its magnetic piston supports compatible sensing options. When regulatory requirements demand specific safety or IP ratings, confirm your application’s environment (dust, washdown, ingress protection) and verify with the supplier for any additional certifications or protective enclosures needed for your facility.
The combination of low-friction seals and non-corrodible materials reduces maintenance intervals and lifecycle costs. The magnetic sensing option enables predictive monitoring through standard switches, helping avoid unexpected downtime. With its compact footprint and easy mounting, installation time is minimized, and retrofit projects can scale across multiple lines, delivering clear ROI through improved uptime and throughput.
