Norgren RM/92020/N4/20 Pneumatic Cylinder - Magnetic Piston
Part Number: RM/92020/N4/20
Quick Summary
RM/92020/N4/20 pneumatic cylinder delivers compact double-acting actuation for automation lines. In space-constrained installations, standard cylinders can overrun the machine envelope, complicating alignment and service. While exact certifications vary by region, this product line commonly aligns with CE conformity and robust IP-rated protection for industrial environments. SIL-ready safety integration is possible through system-level design when used with appropriate sensors. By combining a 20 mm bore with a one-third shorter length than ISO/VDMA equivalents, the unit minimizes footprint while maintaining reliable actuation and long-term durability. That combination reduces maintenance costs and simplifies sensor integration, enabling smarter, more productive automation.

Footprint efficiency drives scalable line layouts and easier retrofits in compact machinery. Feature → Business Impact → Application: The RM/92020/N4/20 is one third the length of a standard ISO/VDMA cylinder, which translates to significant enclosure savings and simpler tube routing in packaging and pick-and-place cells. This enables leaner machine frames and faster changeovers in high-mix, low-volume production. Feature → Business Impact → Application: Low-friction, long-life seal design reduces wear, lowers maintenance intervals, and extends service life in continuous operation environments such as automotive assembly or material handling. Feature → Business Impact → Application: Fully non-corrodible construction—anodised aluminium barrel and stainless steel rod—improves durability in humid or wash-down environments, delivering lower total cost of ownership and fewer unscheduled downtime events on food & beverage packaging lines. Feature → Business Impact → Application: Magnetic piston supports straightforward sensor integration for position feedback, enabling reliable control loops and easier diagnostics in automated inspection stations. Feature → Business Impact → Application: Compact 20 mm diameter with M5 port and double-acting operation simplifies installation and interchangeability across OEM lines, reducing engineering lead times and accelerating time-to-value for new lines. Feature → Business Impact → Application: Theoretical force of 188 N at 6–8 bar makes this actuator suitable for precise actuation, clamping, or short-stroke motions in compact robotic grippers and small transfer mechanisms. Feature → Business Impact → Application: No internal cushioning minimizes motion travel variation at high speeds, while external dampers or customized cushioning can be added for delicate loads, addressing common objections about impact. Across these points, the combination of materials, compact geometry, and sensor-friendly design supports improved reliability, easier maintenance, and better integration with factory-wide automation architectures.

FAQs
The RM/92020/N4/20 is designed for compact actuation with common mounting interfaces. It leverages a standard M5 port and a 20 mm bore, enabling straightforward retrofits into existing frames and end-block configurations typical of small-scale automation cells.
This cylinder operates from 1 to 10 bar (14 to 145 psi) and handles temperatures from -5 to 80 °C (23 to 176 °F), making it suitable for varied shop environments and moderate process conditions.
Yes, its compact footprint and magnetic piston support reliable position sensing and repeatable stroke control. Note that there is no internal cushioning, so for high-speed, high-inertia loads consider external damping or slower actuation profiles as needed.
Exact regional certifications depend on the installation and version, but the RM/92020/N4/20 family is designed to align with common industrial safety and conformity expectations, including CE-related considerations and robust protection standards relevant to pneumatic actuators.
The low-friction seals and non-corrodible materials reduce wear and corrosion risk, extending service intervals, and lowering downtime. The magnetic piston also simplifies sensor integration, enabling easier diagnostics and proactive maintenance planning.
