Norgren RA/192100/N4/25 ISO Compact Cylinder - ISO 21287
Part Number: RA/192100/N4/25
Quick Summary
RA/192100/N4/25 is an ISO Compact double acting cylinder that delivers precise, space-saving pneumatic actuation for automated assembly lines. Engineers often struggle to fit a capable actuator into tight footprints without sacrificing force or repeatability. This model provides a 100 mm bore with a 25 mm stroke, delivering up to 4710 N theoretical force while maintaining a compact profile. It adheres to ISO 21287 and supports magnetic piston switching flush with the profile, reducing misalignment and wiring complexity. The stainless steel piston rod and anodised aluminium barrel resist wear in demanding environments, aligning with typical CE-like safety expectations and IP-rated protection in practice. By combining longevity, predictable performance, and straightforward integration with standard fittings, it offers clear business value through higher uptime and lower maintenance in automated operations.

FAQs
When installing the RA/192100/N4/25, ensure mounting faces are parallel and aligned to the cylinder axis to preserve piston travel accuracy. Use standard G1/8 fittings and compatible brackets to support a flush sensor strategy via the magnetic piston. Confirm supply air is clean and dry within 1–10 bar and consider installing a small inline filter-regulator-lubricator (FRL) to maximize seal life and reduce particulate wear on the rod.
A 100 mm bore provides up to 4710 N of theoretical force, enabling strong actuation in tight spaces. The 25 mm stroke suits short-stroke positioning, clamp cycles, or quick index movements. Real-world speed depends on supply pressure and load; up to reliable, high-repeatability cycles can be achieved with proper lubrication, alignment, and appropriate cushioning for smooth operation.
Yes. The cylinder is designed to conform to ISO 21287, ensuring compatibility with ISO-standard mounting patterns and timing. Its magnetic piston supports deterministic switching, aiding integration with standard sensors and control systems necessary for ISO-compliant machinery. For broader compliance, verify local safety and machine directives (e.g., CE) in conjunction with system-level requirements.
The primary standard is ISO 21287, which defines the ISO Compact cylinder family. In practice, customers look for CE-compliant machinery and IP-rated components for protection against ingress and environmental exposure. While the cylinder is built to rugged industrial norms with corrosion-resistant materials, confirm the exact certification scope with your procurement team and system integrator for your specific application.
Long-life seals and low-friction interfaces reduce downtime and maintenance frequency, improving uptime and throughput. The magnetic piston enables reliable sensing, simplifying diagnostics and reducing wiring complexity. The stainless rod and aluminium barrel resist wear, extending service intervals, while standard fittings ease retrofits and upgrades. Overall, this translates to lower maintenance costs and a favorable return on investment in high-cycle, automated lines.
