Part number
RM/91020/M/25

Quick Summary

RM/91020/M/25 by Norgren is a compact single-acting pneumatic cylinder designed for automated assembly lines and packaging tasks. Space constraints and uptime pressures drive engineers to favor smaller actuators that don’t compromise stroke or force. The range aligns with common certifications and industry expectations, including CE conformity and typical IP protection considerations, while a magnetic piston and low-friction seals deliver dependable operation. With an anodised aluminium barrel and a stainless steel piston rod, the cylinder resists corrosion in challenging environments, while standard magnetism supports simple position sensing. Applied in pick-and-place, clamping and fast-actuation tasks, it reduces maintenance costs and boosts line throughput.

Feature → Business Impact → Application: The RM/91020/M/25 combines a 20 mm bore with a 25 mm stroke to deliver space-efficient actuation that fits into tight packaging and assembly lines, reducing footprint and mounting complexity while maintaining required thrust. This compact form factor translates to lower hardware costs and simpler retrofits on existing equipment, ideal for robotic grippers and small-part handling where throughput matters. Feature → Business Impact → Application: Low-friction, long-life seal design minimizes wear and leakage, extending service intervals and reducing downtime. In practice, this means fewer maintenance cycles and improved overall equipment effectiveness (OEE) on high-speed pick-and-place cells and lightweight clamping operations. Feature → Business Impact → Application: Non-corrodible materials, including an anodised aluminium barrel and austenitic stainless steel rod, resist washdown and humidity exposure, delivering durable performance in harsh environments and enabling longer equipment life in food, beverage, and packaging lines. Feature → Business Impact → Application: Magnetic piston enables easy sensing and feedback integration with standard sensors, simplifying control logic and enabling reliable position verification for automated tooling and safety interlocks in packaging machines. Feature → Business Impact → Application: Operating range of 2 to 10 bar and -5 to 80 °C supports versatile installation across varied plant air systems and environmental conditions, reducing the need for special purpose actuators and accelerating project timelines. Feature → Business Impact → Application: No cushioning keeps stroke response straightforward and predictable, which is advantageous for repeatable actuation in contour-following tasks, though users can add external cushions if their cycle profiles demand softer stops in high-dwell applications.

FAQs

Is RM/91020/M/25 compatible with standard mounting patterns and an M5 port? Yes. It uses a 20 mm bore with an M5 port, and typical mounting options (face, rear, and rod-end) suit many compact automation cells. Verify clearances around the 25 mm stroke and ensure the actuator’s magnetic piston does not interfere with nearby sensors. Quick-connect fittings and compatible brackets simplify retrofits and reduce integration time.
The cylinder presents a theoretical force of 161 N at the nominal conditions, with an operating pressure range of 2 to 10 bar (29 to 145 psi). This makes it suitable for medium-duty actuation in confined spaces. For high-cycle tasks, confirm sensor feedback timing and wiring to ensure reliable control during rapid actuations and to prevent over-travel effects.
Ideal for compact pick-and-place, light clamping, and short-stroke actuation on packaging and small-part assembly lines. Its 20 mm bore and 25 mm stroke are tuned for tight enclosures, while the magnetic piston supports easy position sensing for repeatable cycles. The anodised aluminium housing and stainless rod provide durability in typical factory environments, improving line reliability.
Certification details such as CE conformity and IP protection are common expectations in industrial automation; however, exact ratings should be verified in the official datasheet for RM/91020/M/25. Manufacturers typically provide this information alongside installation and safety guidance, ensuring alignment with your plant’s regulatory requirements and safety programs.
Expect reduced maintenance due to a low friction, long-life seal design and corrosion-resistant materials. The combination of a magnetic piston for simple sensing and a robust exterior reduces downtime and extends service intervals, contributing to a lower total cost of ownership and faster payback in lines with frequent actuations.
