Norgren RM/91025/M/20 Pneumatic Cylinder - Magnetic
Part Number: RM/91025/M/20
Quick Summary
Norgren RM/91025/M/20 is a compact single-acting pneumatic cylinder designed for tight spaces in inline automation, pick-and-place, and clamping applications. When mounting density, lifecycle costs, and corrosion resistance are at the forefront of design challenges, this model trims length and uses durable, non-corrodible materials to help solve those issues. The unit supports a magnetic piston, stainless steel rod, and an anodised aluminium barrel, operating from 2 to 10 bar and temperatures of -5 to 80 C. In safety-conscious environments, devices like this are positioned to meet CE conformity and common IP and SIL expectations, ensuring reliable performance in automated lines. Secondary benefits include easy sensor integration and long service intervals, driving overall equipment effectiveness and lower total cost of ownership.

FAQs
RM/91025/M/20 features a 25 mm bore, 20 mm stroke, single-acting operation, M5 port, 2–10 bar operating pressure, -5 to 80 °C operating range, magnetic piston, stainless steel rod, anodised aluminium barrel, and a theoretical force of 264 N. It uses no cushioning and is designed for compact, high-precision actuation in small automation cells.
The cylinder uses a non-corrodible construction with an anodised aluminium barrel and a stainless steel piston rod, which enhances durability in challenging environments. While it is built for robustness, verify your specific IP rating and washdown requirements with your system integrator to ensure full compliance for your application.
The unit operates from 2 to 10 bar (29 to 145 psi), enabling reliable actuation across a range of lightweight to moderate-load applications in confined spaces.
A magnetic piston enables straightforward position sensing and sensor integration without additional magnets or complex wiring. This simplifies wiring harness design, reduces installation time, and improves repeatability in automated cycles.
The design emphasizes low-friction seals and long life, which reduces wear and maintenance frequency. Its non-corrodible materials contribute to longer service life in challenging environments. Plan routine inspections and sensor checks as part of standard preventive maintenance for high-cycle lines.
