The RM/91025/M/25 is a compact solution that delivers space savings with a length approximately one third of a typical ISO/VDMA model, enabling denser layouts and faster machine cycles in automated lines. Feature → Business Impact → Application: Space-efficient design reduces cabinet footprint and wiring complexity, shortening setup times and lowering installation costs for cramped packaging and pick-and-place cells. Feature → Business Impact → Application: Low friction, long-life seals extend service intervals, reducing maintenance downtime and replacement parts inventory for high-cycle transfer modules. Feature → Business Impact → Application: Fully non-corrodible construction (anodised aluminium barrel, stainless steel rod) improves durability in wash-down environments and harsh industrial settings. Feature → Business Impact → Application: Magnetic piston enables straightforward position sensing with standard switches or encoders, simplifying control integration in robotic grippers and clamp stations. Feature → Business Impact → Application: Broad operating pressure range (2–10 bar) ensures compatibility with common plant air supplies and pressure boosters, supporting flexible line design. Feature → Business Impact → Application: 25 mm bore and 25 mm stroke provide predictable force and stroke for compact actuators, ideal for precise clamping and short-throw tasks. Feature → Business Impact → Application: No cushioning is provided, which benefits high-speed cycles while requiring external consideration for delicate loads; this can be mitigated with system tuning or external damping in demanding applications. Features such as stainless steel piston rod, anodised barrel, and magnetic sensing collectively contribute to lower total cost of ownership through longer service life and simpler maintenance in automation environments.

FAQs

RM/91025/M/25 is engineered for compact installations with a 25 mm bore and 25 mm stroke, and is designed to integrate with standard M5 port fittings. Its reduced length compared to ISO/VDMA models enables denser mounting arrays, simplifying mechanical design and installation in space-constrained automation cells.
Theoretical force is 264 N with a 25 mm stroke, suitable for light to medium actuation tasks. The combination of a small bore and fixed stroke supports fast response times and high-cycle performance, making it well-suited for rapid pick-and-place and clamping actions in compact automation equipment.
Yes, it is rated for operating temperatures from -5 to 80 °C and uses a corrosion-resistant anodised aluminium barrel with a stainless-steel piston rod, delivering reliable performance in harsh environments and under wash-down or outdoor conditions typical of industrial settings.
The unit uses a magnetic piston, enabling straightforward position sensing with standard magnetic switches or encoders. This simplifies integration with existing control systems and PLCs, enabling reliable end-of-stroke detection and synchronized actuation in automated lines.
Low-friction, long-life seals and a fully non-corrodible design extend service intervals and reduce downtime. The magnetic piston aids in simpler sensing-based diagnostics, while the stainless steel rod and anodised barrel resist wear and contamination, contributing to lower total cost of ownership in high-cycle pneumatic systems.
