One of the standout design choices is the significantly shorter length compared to ISO/VDMA models, combined with a low-friction, long-life seal design and a fully non-corrodible specification. The magnetic piston enables versatile control system integration and easy feedback in automation loops. Business impact: footprint reduction allows higher machine density and simpler installation in compact enclosures, while longer seal life reduces maintenance cycles and total cost of ownership. Applications: packaging, assembly, and inline automation lines where space is at a premium. Another key feature is the 25 mm cylinder diameter paired with a 120 mm stroke and a standard M5 port, enabling high-speed actuation in constrained spaces and straightforward valve integration. Business impact: ensures reliable performance in tight automation cells with minimal plumbing complexity. Applications: pick-and-place, machine tending, and transfer operations in compact packaging lines. The barrel is made from anodised aluminium and the piston rod from stainless steel, delivering robust corrosion resistance in damp or dusty environments. Business impact: longer service life reduces unscheduled downtime and maintenance costs. Applications: general industrial environments where humidity or contaminants are present. With a magnetic piston and no cushioning, the design supports precise positioning and fast response with predictable end-of-stroke behavior. Business impact: improved repeatability and cycle accuracy, enabling tighter control loops. Applications: precision clamping, alignment tasks, and high-cycle automation. Theoretical force is rated at 295 N, operating pressure is 1–10 bar, and operating temperature range is -5 to 80 °C, supporting a wide range of process conditions. Business impact: versatile integration across multiple lines and tools, reducing part variants. Applications: general automation and material handling across manufacturing cells.

FAQs

The RM/92025/M/120 is designed for standard mounting with common pneumatic brackets and clevis fittings suitable for a 25 mm bore and M5 port. For installation, align the piston axis with the load, secure with appropriate end brackets or clevis mounts, and ensure a clean, dry air supply within the 1–10 bar range. Use compatible connection hardware to maintain axial alignment and prevent side loads.
Key specs include a 25 mm bore, 120 mm stroke, double-acting operation, 1–10 bar operating pressure, -5 to 80 °C operating temperature, a magnetic piston, anodised aluminium barrel, and a stainless steel piston rod. The theoretical force is 295 N, and the port size is M5. These features enable reliable, compact actuation with straightforward control integration.
Yes. The cylinder employs a low-friction, long-life seal design and a fully non-corrodible construction, with a magnetic piston that supports precise feedback. This combination makes it well-suited for high-cycle applications and harsher environments where corrosion resistance and repeatable performance are critical. For best results, operate on clean compressed air and perform routine inspections to monitor wear and alignment.
The RM/92025/M/120 is designed to support CE marking and compatibility with SIL-rated control schemes, with options for IP-rated environments when paired with suitable accessories. Always verify the exact regulatory scope with the datasheet and your project requirements, as certifications can vary by region and configuration.
Plan maintenance around seal wear, rod cleanliness, and ensuring a dry, oil-free air supply. The design uses low-friction seals and a stainless steel rod to extend life, so routine inspections every 6–12 months are typical in moderate use. Check for leaks, verify stroke accuracy, and replace seals or guides as needed to sustain performance and minimize downtime.
