Norgren RM/92020/N4/25 Pneumatic Cylinder - Magnetic Piston
Part Number: RM/92020/N4/25
Quick Summary
Norgren RM/92020/N4/25 is a compact 20 mm bore, 25 mm stroke pneumatic cylinder designed for precise linear actuation in automated assembly lines. Engineers often face cycle-time constraints and wear in small actuators, so this model minimizes overall length while delivering a long-life seal design. It is CE-compliant, features a magnetic piston for full control versatility, and uses corrosion-resistant materials to withstand demanding environments. With standard M5 porting and a 20 mm bore, it integrates easily with Norgren manifolds, reducing installation time and total cost of ownership for automation projects.

Feature → Business Impact → Application: The RM/92020/N4/25 uses a compact 20 mm bore and 25 mm stroke to deliver a space-saving footprint that enables tighter packaging and faster line layout changes in automated assembly. This translates to measurable gains in installation density and quicker commissioning, especially on multi-axis pick-and-place tasks or small-part handling. Feature → Business Impact → Application: One third the basic length of a corresponding ISO/VDMA model reduces machine length and minimizes actuator volume, enabling leaner machine design and easier retrofit projects in retrofits or line upgrades. Feature → Business Impact → Application: Low-friction, long-life seals decrease wear and maintenance cycles, improving uptime and reducing total cost of ownership in high-cycle packaging and labelling cells. Feature → Business Impact → Application: Fully non-corrodible construction with an anodised aluminium barrel and stainless steel piston rod delivers robust performance in washdown and dusty environments, protecting against corrosion and preserving actuation reliability. Feature → Business Impact → Application: Magnetic piston provides reliable position feedback compatibility with standard sensors, simplifying integration with PLCs and valve manifolds for closed-loop control. Feature → Business Impact → Application: Operating across 1–10 bar and M5 porting ensures easy integration with existing pneumatic systems and FRL blocks, enabling rapid deployment on established lines. Feature → Business Impact → Application: Theoretical 188 N force supports consistent clamping and pushing tasks within small automation cells, delivering predictable actuation without over-specifying components. Feature → Business Impact → Application: Absence of cushioning offers immediate response for precise positioning in high-speed pick-and-place cycles, while still allowing smooth deceleration in tuned systems. Feature → Business Impact → Application: The RM/92000/M range provides a scalable family for standardization across multiple cells, improving spare-part compatibility and procurement efficiency.
