Norgren RM/91025/M/50 Compact Cylinder - Magnetic Piston
Part Number: RM/91025/M/50
Quick Summary
Norgren RM/91025/M/50 is a compact single-acting cylinder designed for precise linear actuation in small pneumatic assemblies. When space is tight and uptime matters, engineers battle bulky actuators and premature seal wear that shorten cycle life. This model aligns with CE safety expectations and leverages a fully non-corrodible construction with a magnetic piston for dependable sensing in harsh environments. Its compact form, durable seals, and corrosion-resistant materials help reduce downtime and lifecycle costs, while the M5 port and 2–10 bar operating range support quick integration into standard automation circuits and tight-line systems.

FAQs
The RM/91025/M/50 uses a standard M5 port and a compact 25 mm bore. It supports multiple orientations and common mounting brackets; ensure secure end caps and correct sensor alignment for magnetic piston feedback. Use compatible fittings and verify supply at 2–10 bar to achieve rated stroke and force.
Operating pressure is 2–10 bar (29–145 psi) with a temperature range from -5 to 80 °C (-23 to 176 °F). This makes it suitable for most general-purpose pneumatic cycles while maintaining performance across typical industrial environments.
No cushioning is built into this model. This yields faster actuation and shorter cycle times, but with reduced end-of-stroke damping. For applications requiring smoother deceleration, consider external stops or cushioning solutions in the downstream mechanism.
Barrel is made from anodised aluminium alloy and the piston rod from stainless steel (austenitic). The design is fully non-corrodible with a magnetic piston, delivering robust performance in challenging environments and enhancing long-term wear resistance.
Best for compact indexing, part feeding, and small actuations in tight automation cells. The magnetic piston enables easy integration with non-contact position sensors for feedback in closed-loop control, reducing wiring complexity and enabling reliable sensing in space-limited layouts.
