Space-saving form: The RM/92050/M/85 is one third the basic length of a corresponding ISO/VDMA cylinder, enabling compact machine envelopes and easier retrofits. Business impact: it reduces panel space, shortens installation time, and lowers overall system weight. Application: ideal for packaging lines, robotic pick-and-place cells, and any installation with limited mounting space. Low friction, long-life seals: The cylinder uses a high-quality seal design that minimizes wear and preserves performance over thousands of cycles, translating to higher line uptime and lower spare-parts costs for manufacturers. Application: high-cycle automation and conveyors. Corrosion-resistant construction: Anodised aluminium barrel and martensitic stainless steel piston rod deliver durability in humid or harsh environments, reducing corrosion-related downtime and extending MTBF. Application: industrial environments with moisture exposure. Sensor-friendly design: A standard magnetic piston enables seamless integration with proximity sensors or switches for reliable feedback and straightforward control-system interfacing. Application: PLC/automation networks requiring clean, non-contact sensing. Operating range and compatibility: With 50 mm bore and 85 mm stroke, G1/8 port, double-acting operation and no cushioning, the unit delivers controlled actuation and predictable force (1178 N theoretical) across 1–10 bar and -5 to 80 °C, aligning with RM/92000/M family compatibility for faster changeovers.

FAQs
Begin by confirming the 50 mm bore and 85 mm stroke fit the fixture. Attach end-mount fittings compatible with the G1/8 ports, connect the air supply to the G1/8 port, and wire the sensor for magnetic piston feedback. Ensure the double-acting cycle is oriented correctly and operate at 1–10 bar to verify leak-free performance.
Key specs include a 50 mm bore, 85 mm stroke, double-acting operation, G1/8 port, operating pressure from 1 to 10 bar, and a temperature range of -5 to 80 °C. It features a magnetic piston, an anodised aluminium barrel, a martensitic stainless steel rod, and delivers up to 1178 N of theoretical force.
Yes. The cylinder uses a non-corrodible construction with an anodised aluminium barrel and stainless steel piston rod, which provides better resistance to moisture and contaminants. While this supports durability in challenging environments, verify regulatory requirements for specific washdown or chemical exposure in your application.
The magnetic piston enables direct, non-contact sensing with proximity switches or position sensors. This simplifies wiring and integration with PLCs or automation controllers, delivering reliable feedback for precise positioning and repeatability without mechanical switches or external sensors.
The design uses low-friction seals to extend life and reduce maintenance cycles, improving uptime. Actual MTBF depends on cycle rate and load. Maintain air quality and perform periodic inspections; replace seals and seals’ carriers per your maintenance plan to maximize performance and minimize downtime.
