Norgren RM/91020/M/5 Pneumatic Cylinder - Magnetic Piston
Part Number: RM/91020/M/5
Quick Summary
RM/91020/M/5 is a compact single-acting pneumatic cylinder designed for precise linear actuation in automated packaging, assembly, and pick-and-place lines. In space-constrained installations, reducing footprint is a critical project driver; this model provides one third the basic length of a corresponding ISO/VDMA cylinder, helping streamline enclosure design and installation schedules. The unit features a fully non-corrodible specification and a standard magnetic piston, with a wide operating window from -5 to 80 °C and 2 to 10 bar, making it suitable for variable factory environments. Its magnetic sensing compatibility and robust materials support reliable actuation while keeping total cost of ownership low. For compact automation, RM/91020/M/5 pairs well with standard fittings and sensors.

FAQs
RM/91020/M/5 uses an M5 port, allowing compatibility with a wide range of standard pneumatic fittings and manifolds. Its compact form factor simplifies retrofits in crowded machines, and it pairs with typical 4/2 or 3/2 valve configurations to deliver reliable single-acting actuation. When selecting hoses or tubing, ensure you match inner diameter to M5 fittings and consider vibration resistance in high-cycle environments.
The cylinder operates from 2 to 10 bar and from -5 to 80 °C. This broad range supports most common industrial environments, enabling dependable performance in packaging, assembly, and light tooling tasks. For extreme conditions, verify enclosure protection and ensure materials are suitable for your specific media and ambient conditions.
Yes. Its 20 mm bore with 5 mm stroke and low-friction, long-life seals provide consistent actuation with reduced wear, supporting higher cycle rates. The standard magnetic piston also facilitates reliable position sensing, enabling precise control in repetitive pick-and-place tasks while maintaining a compact footprint.
The provided data does not list specific certifications. For regulated environments or safety-critical applications, consult the full Norgren datasheet or contact the supplier to confirm CE marking, IP ratings, SIL compliance, or other certifications relevant to your installation. Always validate certifications with your procurement and safety teams before deployment.
The cylinder features a low-friction, long-life seal design and a fully non-corrodible construction, which reduces maintenance frequency and part replacements. The magnetic piston supports easy monitoring and fewer mechanical failures, while the anodised barrel and stainless steel rod resist wear. Together, these traits lower total cost of ownership and improve line uptime in routine automation tasks.
