Norgren RM/92025/M/50 Pneumatic Cylinder - Magnetic Piston
Part Number: RM/92025/M/50
Quick Summary
Norgren RM/92025/M/50 pneumatic cylinder is a compact double-acting actuator designed for precise linear motion in constrained automation spaces. When panel real estate or machine footprint is a constraint, this 25 mm bore, 50 mm stroke cylinder delivers reliable performance without sacrificing stroke length. Engineers often struggle with mounting versatility and long service life in demanding environments; this unit addresses those concerns with a low-friction seal design and a fully non-corrodible specification. The standard magnetic piston enables easy position sensing and compatibility with switch-and-sensing configurations already used in modern control architectures. While the data here does not specify formal certifications, vendors and integrators typically prioritize CE readiness, IP protection, and SIL considerations when deploying pneumatic cylinders in safety-critical systems. With high-quality materials and a robust range compatible with RM/92000/M, this cylinder supports scalable automation and reduced downtime.

FAQs
The RM/92025/M/50 supports Pneufit C push-in fittings (examples C02250405 and C02470405) and a range of mountings, including Nut style N2 and various bracket configurations. Mounting options such as QM/90025/21 foot mounting, QM/90025/22 front/rear flange, and M/P1501/79 nut options enable flexible, repeatable installation on 25 mm bore actuators. This ecosystem simplifies retrofits and new builds alike by ensuring compatibility with RM/92000/M family accessories.
The RM/92025/M/50 uses a magnetic piston, enabling straightforward integration with reed switches such as M/50 LSU/5V and compatible switch brackets (M/P72487B). This configuration supports reliable end-of-stroke detection and simple wiring to standard control systems, reducing customization time and improving cycle accuracy in automated lines.
This cylinder operates from -5 to 80 °C and supports an air pressure range of 1 to 10 bar (14 to 145 psi). These ranges accommodate typical factory environments and most pneumatic networks, providing predictable actuation without excessive wear when used with clean, dry compressed air and proper line sizing.
With a 25 mm bore and 50 mm stroke, double-acting operation, and a compact footprint, this actuator is well-suited for packaging, machine tending, and small-part handling. Its magnetic piston simplifies sensing for automation, while the corrosion-resistant materials support reliability in packaging lines, assembly stations, and other space-constrained workflows requiring precise, repeatable motion.
Thanks to a low-friction seal design and fully non-corrodible construction, the RM/92025/M/50 offers long service life with reduced wear. Regular inspections should verify mounting alignment to avoid side loads, check for air leaks at the M5 connections, and ensure clean, dry air supply. Optional accessories and correct fittings help minimize downtime and extend actuator life in demanding environments.
