Norgren RM/92050/M/125 Pneumatic Cylinder - Magnetic
Part Number: RM/92050/M/125
Quick Summary
The Norgren RM/92050/M/125 pneumatic cylinder provides compact double-acting actuation for precise linear motion in automation systems. In tight machines, space and wear are common pain points; this model achieves one-third the length of a comparable ISO/VDMA cylinder while delivering reliable, low-friction performance. Although exact SIL, CE, or IP certifications aren’t listed on the datasheet, the design emphasizes CE compatibility, a fully non-corrodible construction, and a magnetic piston that enables easy integration with safety interlocks. Together with standard fittings and mounting options, the RM/92050/M/125 helps engineers reduce downtime and ensure repeatable performance in factory automation.

FAQs
This cylinder supports standard mountings such as front/rear flange (QM/90050/22 and QM/90050/21) and connector adaptors; M/P71470/1 provides stud or adaptor mounting for attaching F mounting to the piston rod thread. For quick installation, consider the Pneufit C fittings (C0K510618) and straight or 90° adaptor choices (C02470618, C02250618). These options reduce assembly time and allow easy retrofits into existing systems.
Key specs include a 50 mm bore, 125 mm stroke, double-acting operation, G1/8 port size, and a 1–10 bar operating pressure range (-5 to 80 °C, 14–176 °F). Theoretical force is 1178 N, with magnetic piston and corrosion-resistant materials (anodised aluminium barrel and martensitic stainless steel rod). These values guide cycle rate, load capacity, and sensing options in automation cells.
Yes, its design emphasizes durability for industrial environments: a non-corrodible specification, anodised aluminium barrel, and a martensitic stainless steel piston rod. The magnetic piston supports integration with safety interlocks, and the unit is intended for broad temperature and pressure ranges. For heavy wash-down or aggressive media, pair with compatible fittings and protective housings to maximize uptime.
Service kits for RM/92000-series 50 mm cylinders are available (QM/92050/00), designed to simplify maintenance of the RM/92050/M/125 family. Regular seal inspections and periodic replacement with OEM service kits help preserve sealing performance, extend life, and minimize unplanned downtime in continuous operation environments.
The M/50 magnetically operated reed switch (5 m cable) enables reliable non-contact position sensing with minimal wiring, reducing installation complexity and wiring costs. This improves diagnostic visibility, cuts panel wiring time, and can shorten preventive maintenance cycles, contributing to faster commissioning and a lower total cost of ownership in automated lines.
