Norgren RM/92040/M/180 Pneumatic Cylinder - One-Third Length
Part Number: RM/92040/M/180
Quick Summary
Norgren RM/92040/M/180 is a compact double-acting pneumatic cylinder ideal for automation in tight spaces. It minimizes footprint and weight while delivering long-life seals and low friction to reduce downtime and maintenance costs. While many similar actuators struggle with stroke length or rapid wear, this model is designed for durability, using an anodised aluminium barrel and stainless steel piston rod, with a magnetic piston enabling easy sensing and control integration. The unit operates from 1 to 10 bar and tolerates -5 to 80 °C, supporting diverse environments. By combining a reduced overall length with robust construction, it helps you consolidate cylinders, simplify kitting, and lower total cost of ownership on production lines.

FAQs
RM/92040/M/180 uses a standard 40 mm bore with a G1/8 port, enabling straightforward mounting to common ISO cylinder footprints. Ensure proper alignment with existing mounting brackets and verify that the actuator’s stroke aligns with the application travel. Use compatible end brackets and ensure coolant or wash-down exposure is considered where applicable. Always follow the datasheet guidelines for torque limits on mounting screws to avoid over-constraining the rod.
The RM/92040/M/180 operates from 1 to 10 bar (14–145 psi) and tolerates temperatures from -5 to 80 °C (-23 to 176 °F). This range supports most standard industrial environments, including moderate wash-down areas when used with appropriate protection and mounting hardware. For extreme environments, consider additional enclosure or seals as required by your specific application.
The cylinder provides robust force (754 N theoretical) and a 180 mm stroke in a compact package, which suits many packaging tasks. However, it has no internal cushioning, so for high-speed, high-acceleration cycles you may need external speed control or dashpot solutions. Its magnetic piston aids sensing for precise cycle timing, which supports reliable performance in speed-sensitive lines while maintaining system simplicity.
The RM/92040/M/180 is designed for integration into CE-compliant European machinery, with a magnetic piston supporting sensor-based control. While data sheets emphasize general industrial compatibility, verify your exact regulatory and IP requirements with the datasheet and supplier guidance, especially for wash-down or hazardous-area installations. If SIL-rated control is needed, coordinate with your control system to ensure suitable safety architecture.
The combination of low-friction seals, corrosion-resistant barrel, and a stainless steel piston rod reduces wear and downtime, improving mean time between failures (MTBF). The compact length simplifies spare-part inventories and retrofit projects, lowering total cost of ownership. Magnetic sensing also reduces wiring complexity and improves diagnostic capabilities, contributing to faster maintenance and better system uptime.
