One of the RM/92025/M/85's standout features is its compact length—roughly one third of a comparable ISO/VDMA model. This space savings translates directly to smaller actuator housings and shorter machine envelopes, enabling tighter layout in packaging, assembly cells, and inline automation projects. The low-friction, long-life seal design minimizes wear and friction, extending service intervals in high-cycle environments, which reduces unplanned stops and maintenance costs. Fully non-corrodible materials protect performance in challenging environments, preserving reliability when dust, humidity, or exposure to mild chemicals is present. A standard magnetic piston enables straightforward integration with sensors and control hardware, supporting reliable position feedback without additional components. The anodised aluminium barrel and stainless steel piston rod provide a durable balance of light weight and corrosion resistance, easing installation and long-term operation. The cylinder operates from 1 to 10 bar and tolerates -5 to 80 °C, offering a versatile envelope for diverse factory floors. An M5 port size ensures compatibility with common valve manifolds and fittings, while the RM/92000/M range provides scalable options for stroke variations and mounting configurations for future-proof automation.

FAQs
When installing the RM/92025/M/85, ensure the mounting face is clean and aligned to protect stroke accuracy. Use compatible M5 fittings to connect standard pneumatic valving and ensure the double-acting ports are correctly plumbed for extend and retract actions. Given the no-cushioning configuration, confirm return path clearance to avoid contact with adjacent components and verify magnetic sensing alignment for reliable position feedback.
The cylinder supports an operating pressure range of 1 to 10 bar (14 to 145 psi) and a temperature range of -5 to 80 °C (23 to 176 °F). This enables use across diverse equipment and environments, from standard factory floors to hotter automotive lines, while maintaining consistent actuation performance.
Yes, its low-friction, long-life seal design addresses wear and friction typical of high-cycle lines, reducing maintenance frequency. The magnetic piston supports reliable sensing for closed-loop control, keeping cycle accuracy stable. For extreme high-cycle applications, consider scheduling preventive maintenance to monitor seal wear and verify sensor alignment.
The barrel is made from anodised aluminium alloy, and the piston rod is stainless steel (austenitic). This combination offers good strength-to-weight with excellent corrosion resistance, supporting longevity in challenging environments and reducing the risk of galling or ingress-driven wear that can affect performance over time.
A key differentiator is its compact profile—about one third the length of a comparable ISO/VDMA cylinder—allowing smaller machine footprints and easier installation in tight spaces. It also features a standard magnetic piston for straightforward sensing and a fully non-corrodible construction, aligning with common automation practices and simplifying system integration.
