Norgren RM/91020/M/10 Compact Cylinder - Magnetic
Part Number: RM/91020/M/10
Quick Summary
The Norgren RM/91020/M/10 compact single-acting cylinder delivers precise actuation for compact automation tasks. In tight spaces, engineers face stroke limitations, misalignment, and wear that disrupt cycle times and increase maintenance. Although the datasheet notes a magnetic piston and corrosion-resistant build, verify CE, IP, and SIL applicability with the official datasheet. This design delivers reliable, space-saving performance with low-friction seals and a fully non-corrodible specification, while standard mounting and fittings simplify integration into existing lines and help reduce total cost of ownership in discrete manufacturing and packaging environments.

One key feature is the cylinder’s compact form factor with a bore of 20 mm and a stroke of 10 mm, delivering one third the length of a corresponding ISO/VDMA model. Business impact: allows tighter machine footprints and shorter cycle paths, enabling faster line throughput in high-density automation layouts. Application: suitable for small pick-and-place modules and accessory actuation in automotive, packaging, and electronics assembly lines. The long-life, low-friction seal design reduces wear and maintenance, improving uptime and reducing replacement costs over the device’s lifecycle while supporting predictable cycle times in high-frequency operations. The fully non-corrodible construction with anodised aluminium barrel and stainless steel piston rod enhances longevity in damp or contaminant-prone environments, meaning lower downtime for cleaning or part replacement. This translates to lower lifecycle costs and greater process reliability for OEMs and end users. The magnetic piston enables straightforward sensing compatibility with M‑series switches, and the standard M5 port size ensures quick integration with Pneufit C fittings, simplifying installation and field maintenance. In practice, these features reduce assemblies’ complexity and support faster changeovers and easier preventative maintenance planning.

FAQs
Install the RM/91020/M/10 on a stable mounting surface using the available 20 mm bore foot or flange options. Connect M5 pneumatic lines via Pneufit C push-in fittings for fast, tool-free assembly. Ensure porting aligns with system circuits and verify that the supply pressure remains within 2 to 10 bar for reliable cycling. The actuator’s compact length helps minimize misalignment risk in tight spaces.
The RM/91020/M/10 provides a theoretical force of 161 N at typical operating conditions. It is designed to operate within 2 to 10 bar (29 to 145 psi) of compressed air, making it suitable for small, rapid actuations in compact automation cells. Selection should consider dynamic loads and mounting configuration to ensure consistent performance.
Yes. With a 20 mm bore and a 10 mm stroke, the RM/91020/M/10 excels in constrained spaces common to pick-and-place and small-part handling. Its short overall length relative to ISO/VDMA equivalents reduces enclosure size, while the magnetic piston supports easy sensing for precise end-of-stroke detection during high-speed pick-and-place cycles.
The provided data does not specify CE, IP, or SIL ratings for this model. For regulatory compliance and suitability in your environment, consult the official Norgren datasheet (Datasheet PDF) and your procurement standards. Look for CE marking, IP protection level, and any safety-related certifications applicable to your application, particularly in food, pharmaceutical, or safety-critical systems.
The cylinder uses low-friction, long-life seals and a fully non-corrodible construction with an anodised aluminium barrel and stainless steel piston rod. These choices reduce wear, minimize corrosion-related downtime, and extend service intervals. The magnetic piston also simplifies retrofitting with non-contact sensors, enabling quicker diagnostics and improved uptime in production lines.
