Norgren RM/92050/N4/25 Pneumatic Cylinder - Magnetic Piston
Part Number: RM/92050/N4/25
Quick Summary
The RM/92050/N4/25 is a compact double-acting pneumatic cylinder designed for precise linear actuation in automation lines. In tight machinery, space constraints often limit stroke, mounting options, and cycle speed; this model delivers a significantly shorter length while preserving a 50 mm bore and 25 mm stroke. The unit features a fully non-corrodible body, low-friction, long-life seals, and a standard magnetic piston for versatile sensing and control integration—key for modern PLC and valve-rail architectures. While many Norgren products in this family align with CE compliance and robust IP-rated variants, always verify the current certification scope for your application. Pairing with compatible fittings and mounting options accelerates installation and reduces integration risk across production environments.

The compact footprint with a 50 mm bore and 25 mm stroke reduces installation envelope, enabling higher line density and faster changeovers in automated assemblies. This space efficiency translates into lower capital costs per axis and simpler maintenance access on crowded production lines. The low-friction, long-life seals extend service intervals, delivering lower downtime and reduced maintenance spend over the cylinder’s life. Anodised aluminium barrel and stainless steel piston rod provide corrosion resistance, ensuring reliable performance in harsher environments and minimizing replacement frequency. The magnetic piston enables straightforward sensing and integration with reed switches and control hardware, speeding up commissioning and improving process visibility. Compatibility with Pneufit C push-in fittings and standard mounting options simplifies installation and reduces engineering time. With a broad operating range of 1–10 bar and -5 to 80 °C, it maintains consistent performance across typical plant air systems.

FAQs
RM/92050/N4/25 supports multiple mounting configurations: M/P71470/1 stud or adaptor mounting for attaching F mounting to the female piston rod thread; QM/57025/25 Piston Rod Clevis Mounting for 25 mm bore; QM/90050/21 C - Foot Mounting for 50 mm bore; QM/90050/22 BG - Front / Rear Flange Mounting for 50 mm bore. These options enable reliable, easy-to-align installations across a range of equipment layouts.
The cylinder uses G1/8 port size. It operates from 1 to 10 bar (14 to 145 psi) and withstands temperatures from -5 to 80 °C (23 to 176 °F), making it suitable for standard plant air systems and diverse industrial environments.
Yes. With a compact overall length and a 50 mm bore, the RM/92050/N4/25 fits restricted spaces while delivering reliable double-acting actuation. Its low-friction seals and magnetic piston support repeatable movement and easy sensor integration in high-density pick-and-place setups.
A magnetically operated reed switch option is available (example: M/50/LSU/5V). The magnetic piston supports straightforward integration with sensing elements, enabling reliable position feedback and control into PLCs or valve manifolds.
Service kits are available under QM/92050/00 for RM/92000 50 mm variants, supporting routine maintenance. For sensing components, M/50/LSU/5V switches are compatible with the standard connector and cabling. Regular seal and rod maintenance helps maximize life and minimize unexpected downtime.
