Quick Summary

Norgren RM/92040/N4/20 is a compact double-acting pneumatic cylinder for precise linear actuation in automation and machinery. Engineers often struggle with space constraints and wear-limited cycles that throttle cycle times and uptime. This design aligns with industry-standard certifications; for specifics like CE conformity and IP-related ratings, consult the datasheet. This model’s magnetic piston and corrosion-resistant barrel support reliable control and long service life, while its 40 mm bore and 20 mm stroke enable 754 N of theoretical force at typical pressures. Designed for compatibility with standard ISO/VDMA interfaces, it helps reduce integration risk and shorten setup time, delivering measurable efficiency gains.

Compact length reduces the machine footprint and mounting complexity, enabling tighter packaging and easier retrofit in existing lines. This directly lowers installation costs and frees space for ancillary equipment, improving overall line density and throughput in automated cells. The magnetic piston provides straightforward feedback and seamless integration with sensors and PLCs, enhancing control accuracy and reducing commissioning time during changeovers. Low friction, long-life seals minimize wear and maintenance needs, delivering lower life-cycle costs and fewer unplanned downtime events in continuous operation environments. The anodised aluminium barrel and stainless steel piston rod offer corrosion resistance and robust performance across a wide operating temperature range (-5 to 80 °C) and pressure range (1 to 10 bar), supporting longer service intervals and predictable actuation. The 40 mm bore with a 20 mm stroke supplies up to 754 N of theoretical force, suitable for medium-duty actuation tasks such as clamping, pushing, and alignment in compact automation setups. No cushioning is included by default, which simplifies actuation and installation; if cushioning is required for smoother deceleration, consider compatible variants or external cushioning options. The one-third basic length advantage compared to certain ISO/VDMA models reduces external mounting footprint, enabling denser machinery layouts and easier retrofits in existing lines.
