Norgren RM/91025/M/5 Pneumatic Cylinder - Magnetic
Part Number: RM/91025/M/5
Quick Summary
Norgren RM/91025/M/5 pneumatic cylinder delivers compact actuation for precise linear motion in automation and packaging lines. When space is at a premium, its one-third the length of a comparable ISO/VDMA model minimizes envelope while maintaining force. Engineers face wear and sealing challenges in high-cycle environments; this unit offers a long-life, low-friction seal design and a standard magnetic piston to simplify sensing. Designed for compressed air at 2–10 bar and temperatures from -5 to 80 °C, it supports reliable performance in harsh factory conditions. Certification details should be confirmed with the supplier, including CE marking and IP ratings where required. By combining compact form with magnetic sensing and durable materials, it reduces maintenance and downtime while lowering total cost of ownership.

FAQs
The RM/91025/M/5 uses a 25 mm bore with an M5 port to suit compact, machine-mounted setups. For reliable performance, pair with compatible mounting brackets or manifolds designed for 25 mm bore cylinders, ensuring alignment with the pneumatic supply and control lines. Consider external end fittings and sensor placement that accommodate the magnetic piston without obstructing stroke.
This model provides a 25 mm bore with a 5 mm stroke and a theoretical force of 264 N. It operates on compressed air at 2–10 bar and withstands temperatures from -5 to 80 °C. It is a single-acting cylinder with magnetic sensing and no cushioning, suitable for rapid, short-stroke actuation in constrained spaces.
Yes, its compact form factor and 264 N theoretical force support short-stroke pick-and-place and light clamping tasks in packaging lines where space is limited. However, since it has no cushioning, assess end-of-stroke impacts and consider alternative models or external cushioning if your application requires softer deceleration or reduced impact at cycle end.
Certification details are not listed in the provided data. When selecting for regulated environments, confirm required standards such as CE marking or relevant IP ratings with the supplier. Verify compatibility with your plant safety standards and approval processes, and request from the manufacturer any third-party test reports or conformance certificates applicable to your region.
Leverage the cylinder’s long-life, low-friction seals and corrosion-resistant materials to minimize downtime. Schedule periodic inspections of the piston rod and seals, ensure clean, dry compressed air, and verify port connections remain leak-free. The magnetic piston simplifies sensor integration, reducing wiring faults and maintenance time, contributing to higher uptime and lower total cost of ownership over the product life.
