The RA/802050/M/25 provides a 50 mm bore with a 25 mm stroke, conforming to the ISO 15552 standard for easy interchangeability and fast replacement in existing lines. This translates to reduced downtime and lower spare-parts inventories for high-volume applications in pick-and-place, clamping, and positioning tasks. The compact, anodised aluminium barrel and stainless steel piston rod deliver a durable, corrosion-resistant core that minimizes wear in demanding environments while keeping weight manageable for swift actuator cycling. Polyurethane seals lower friction for smoother operation, extending service intervals and cutting energy costs during high-frequency cycles. The magnetic piston rod enables reliable reed-switch actuation for safe, accurate positioning and simpler automation integration. ACS adaptive cushioning minimizes impact and vibration, improving repeatability and reducing downstream vibration that can affect downstream tooling or sensors. Engineers benefit from predictable performance in robotics, packaging lines, and material handling where tight tolerances matter. The cylinder’s G1/4 port sizing and ISO-standard mounting options simplify installation and spare-part compatibility, reducing project lead times and enabling rapid scale-up. Overall, the RA/802050/M/25 delivers robust, low-maintenance performance with measurable efficiency gains and a clear path to lower total cost of ownership across automated systems.

FAQs
RA/802050/M/25 supports ISO 15552 standard mounting patterns and multiple mounting accessories including swivel hinge, rear eye, D2 rear clevis, and universal rear eye configurations. With 50 mm bore and 50 mm mounting centers common in modular systems, integration is straightforward across many automation cells. Switch brackets and piston-rod mountings are available to align with sensors and end-of-stroke switches, simplifying control logic and enabling quick retrofit projects.
The cylinder operates from 1 to 16 bar (14 to 232 psi). Theoretical force is specified as 1178 N at full bore and stroke, enabling consistent drive in standard pick-and-place tasks and clamping operations. This combination delivers reliable performance across typical industrial environments while preserving seal life and reducing peak load stress on connected components.
Yes. The RA/802050/M/25 is designed around the ISO 15552 standard, ensuring interchangeability with other ISO-series cylinders. Its 50 mm bore, 25 mm stroke, and robust ACS cushioning support repetitive packaging operations, delivering consistent positioning accuracy and minimized maintenance overhead. Its magnetic rod and durable materials further enhance automation reach in high-cycle packaging environments.
Adaptive Cushioning System (ACS) adjusts the hydraulic-like cushioning to match load profiles, reducing impact at end-of-stroke and lowering vibration across the stroke. This protects mechanical interfaces, reduces wear on seals and rods, and improves repeatability, particularly in high-speed or high-cycle applications. ACS also contributes to quieter operation and helps maintain precise sensor alignment during rapid cycles in assembly lines.
Service kits for PRA/801, PRA/802, PRA/803, RA/801, RA/802, RA/803, PRA/181, PRA/182, RA/181, RA/182, RA/8000, and related 50 mm diameter cylinders are recommended to sustain performance. Regular seal and cushion maintenance, plus periodic replacement of wear parts in line with cycle demands, helps maintain consistent force and stroke accuracy. Availability of mounting hardware and push-in fittings (Pneufit C) simplifies ongoing maintenance and reduces downtime.
