Norgren RM/92020/N4/80 Pneumatic Cylinder - Magnetic
Part Number: RM/92020/N4/80
Quick Summary
Norgren RM/92020/N4/80 is a compact double-acting pneumatic cylinder for precise linear actuation in automation systems. It addresses space constraints and long-term wear by delivering a shorter form factor without compromising stroke or performance. While the data does not specify CE, SIL, or IP certifications, the unit uses a corrosion-resistant anodised aluminium barrel and a magnetic piston that enable reliable control integration across standard automation environments. This combination supports efficient maintenance and predictable cycle life, while the 20 mm bore and 80 mm stroke align with common module sizes, enabling cost-effective scalability. For engineers, this translates to streamlined integration with existing controls, robust sensing, and consistent performance in compact installations.

FAQs
Mount the cylinder using standard Norgren mounting accessories compatible with a 20 mm bore. Ensure the M5 port sizing matches your air supply lines, and orient the rod to minimize side load. Use appropriate end attachments and seals to maintain alignment and avoid cross-axis forces. Check the datasheet for torque recommendations and bracket options to preserve straight-line motion.
The RM/92020/N4/80 provides a theoretical force of 188 N at the specified operating conditions. It is designed to operate from 1 to 10 bar and within a temperature range of -5 to 80 °C. For peak performance, supply a clean, dry air line and ensure the system pressure remains within this band during cycles to avoid stalling or drift.
The cylinder combines a corrosion-resistant anodised aluminium barrel with a stainless steel piston rod and a magnetic piston, offering durability in many industrial environments. While the data does not specify cleanroom suitability or specific high-cycle ratings, its robust materials and magnetic sensing compatibility make it a good fit for many general automation tasks. Verify line cleanliness and its compatible sensors for cleanroom use.
The provided data does not list explicit CE, SIL, or IP ratings. For regulatory compliance, consult the datasheet linked in the product page or contact the supplier to confirm certifications. In practice, Norgren products often align with standard industrial controls, but certification status should be validated for your specific application and market.
Take advantage of the low-friction, long-life seal design and magnetic piston for reliable sensing. Regularly inspect end fittings and the air supply for contaminants, and schedule preventive maintenance based on cycle counts. If cushioning is required for sensitive equipment, consider selecting a version with cushioning or integrating external deceleration to extend seal life and reduce system wear, improving uptime and total cost of ownership.
