Norgren RM/93025/M/20 Pneumatic Cylinder - One Third Length
Part Number: RM/93025/M/20
Quick Summary
RM/93025/M/20 is a compact pneumatic single-acting cylinder formulated for precise linear actuation in automation and assembly lines. In space‑constrained environments, traditional cylinders often struggle to fit or deliver consistent stroke, but this model reduces footprint without compromising performance. Key specifications support reliable operation: 25 mm bore, 20 mm stroke, 2–10 bar range, anodised aluminium barrel, and a stainless steel piston rod with a magnetic piston for dependable sensing. Certifications are not listed in the provided dataset; please consult the datasheet for CE, IP, and SIL approvals. For procurement teams, the combination of space savings, corrosion resistance, and standard M5 port compatibility translates to shorter installation times and lower maintenance, boosting overall equipment effectiveness in packaging and automation lines.

The RM/93025/M/20 couples a 25 mm bore with a 20 mm stroke to deliver a compact actuator that fits where space is at a premium, enabling installation alongside other actuators in tight automation cells and robotic end-effectors. This density in a single-acting cylinder reduces overall system footprint and simplifies mechanical design, which in turn lowers installation time and reduces enclosure spacing requirements. The design leverages low friction, long-life seals to extend service intervals and decrease maintenance costs, delivering higher line uptime and a lower total cost of ownership for high-cycle packaging and material-handling tasks. Fully non-corrodible specifications, including an anodised aluminium barrel and stainless steel piston rod, protect performance in humid or wash-down environments, improving longevity and reliability in harsh production lines. A standard magnetic piston enables easy sensing for proximity or home-position detection, reducing wiring complexity and enabling robust, scalable automation integration. Compatibility with common M5 porting and the RM/93000/M range supports straightforward retrofit or system expansion across existing pneumatic networks. When used in controlled applications, the absence of integrated cushioning can be mitigated by external cushions or compatible variants to manage impact and cycle speed, ensuring suitability for high-speed automation and precision stop requirements. Theoretical force of 197 N at typical operating conditions provides clear sizing guidance for actuation loads, while the 2–10 bar working range covers most plant air supplies without over-pressurization. Overall, this cylinder aligns with modern intelligent manufacturing needs, delivering space savings, predictable performance, and easier sensor integration for streamlined automation.

FAQs
Install RM/93025/M/20 by mounting the cylinder using standard hardware aligned with the M5 port. Ensure bore alignment with the actuator rod and connect compressed air supply within the 2–10 bar range. Verify piston travel against the desired stroke length (20 mm) and use prox sensors for position feedback due to the magnetic piston. Confirm compatibility with your manifold and mounting feet to minimize cycle interference.
The cylinder has a theoretical force rating of 197 N, which scales with applied pressure within the 2–10 bar range. At 6 bar, you can approximate peak actuation force around the nominal value, accounting for dynamic frictions and load. Use this figure for initial cylinder sizing, then validate in your actual application under cycling and your specific load profile.
Yes for many high-cycle tasks, thanks to low-friction seals and a robust non-corrodible build. However, the unit has no built-in cushioning, so for high-speed or delicate stops you should add external cushioning or select a model with integrated cushioning to prevent impact wear and vibration, ensuring longevity in demanding production lines.
Maintain performance by supplying clean, dry compressed air and inspecting for seal wear at regular intervals. The anodised aluminium barrel and stainless steel rod resist corrosion, but routine checks on mounting, fittings, and connections help prevent leaks and misalignment. Use standard lubrication practices as recommended for your broader pneumatic system and ensure proper filtration to protect seals from contaminants.
Yes. The magnetic piston enables straightforward position sensing with non-contact proximity sensors, simplifying wiring and control logic. This feature supports reliable end-of-stroke detection and easier integration with PLCs and automation sequences, reducing setup time and boosting repeatability in packaging, pick-and-place, and assembly lines.
