Norgren RM/91040/M/15 Compact Cylinder - Magnetic Piston
Part Number: RM/91040/M/15
Quick Summary
Norgren RM/91040/M/15 is a compact single-acting pneumatic cylinder designed for precise linear actuation in automated assembly and packaging lines. Space constraints and maintenance costs are common pain points in small actuators; this model reduces length to one-third of a typical ISO/VDMA cylinder while delivering low-friction, long-life seals for fewer replacements. It features a fully non-corrodible construction with a magnetic piston, enhancing reliability in demanding environments. Operating from -5 to 80 °C and 2 to 10 bar, it integrates smoothly with standard compressed-air systems, offering predictable performance in tight spaces and compact toolings.

FAQs
The RM/91040/M/15 is designed for compatibility with ISO/VDMA dimensional standards and standard pneumatic interfaces. With a 40 mm bore, 15 mm stroke and G1/8 port, it aligns with common mounting patterns and piping layouts. Ensure correct mounting to support a theoretical load of 687 N and verify that operating conditions remain within -5 to 80 °C and 2 to 10 bar. Sensor integration is straightforward thanks to the magnetic piston.
Key specs include a 40 mm cylinder diameter, 15 mm stroke, G1/8 port size, single-acting operation, no cushioning, magnetic piston, and 687 N theoretical force. It operates on compressed air over a temperature range of -5 to 80 °C and pressure range of 2 to 10 bar. Materials are anodised aluminium for the barrel and stainless steel for the piston rod, offering durability with light weight.
Yes, its compact length and 40/15 mm dimensions suit tight spaces, and the magnetic piston supports reliable feedback for sensing applications. The low-friction seals help sustain higher cycle rates, while the absence of cushioning reduces internal travel resistance. For ultra-high-speed cycles, verify system airflow, valve response times, and the mechanical limits of your tooling to avoid stalling.
The provided data emphasizes ISO/VDMA compatibility and standard pneumatic construction, with a magnetic piston and corrosion-resistant materials. Explicit certifications such as CE, SIL, or IP ratings are not listed. For compliance-specific requirements, consult the supplier or request formal certification documentation to confirm any regional regulatory needs.
The design emphasizes long life with low-friction seals and a non-corrodible build, reducing wear and maintenance intervals. Regular inspections should cover seal wear, piston rod integrity, and port cleanliness. Since cushioning is not included, monitor impact loads on end positions and ensure correct mounting to minimize misalignment, which can shorten life in high-cycle environments.
