Norgren RM/92020/JM/25 Compact Cylinder - One-Third Length
Part Number: RM/92020/JM/25
Quick Summary
Norgren RM/92020/JM/25 Compact Pneumatic Cylinder is a double-acting actuator designed for space-constrained automation tasks. In tight machines and robotic cells, limited space can force compromises between stroke, speed, and reliability. This model helps balance those constraints with a 20 mm bore and a 25 mm stroke in a significantly shorter package. CE-compliant where applicable and IP-rated variants are available; consult the datasheet for exact ratings and suitability. Built for longevity, it features a low friction, long-life seal design and a fully non-corrodible specification. The magnetic piston supports easy sensor integration, while the materials choice reduces maintenance requirements and total cost of ownership. Use cases span assembly, packaging, and compact automation lines where dependable actuation matters most.

Feature → Business Impact → Application: The RM/92020/JM/25 is one third the length of comparable ISO/VDMA cylinders, freeing valuable machine footprint and simplifying enclosure design, which reduces installation time and overall system cost in compact packaging lines. In practice, manufacturers see smoother layouts and faster line integration, especially in robotic pick-and-place stations. Feature → Business Impact → Application: Low friction, long-life seals deliver consistent performance over high cycle counts, cutting maintenance downtime and extending service intervals in continuous manufacturing environments. This translates to higher throughput and lower total cost per part on food, beverage, and electronics lines. Feature → Business Impact → Application: Fully non-corrodible construction (anodised barrel, stainless steel rod) improves durability in challenging environments, supporting washdown capable installations and longer service life in harsh ambient conditions. Feature → Business Impact → Application: Magnetic piston enables seamless sensor feedback and position detection without intrusive wiring, accelerating PLC integration and safeguarding repeatable stroke retention across multiple stations. Feature → Business Impact → Application: 1–10 bar operating pressure and -5 to 80 °C range provide versatile installation across robotics, packaging, and automation modules, reducing design constraints and improving system robustness.

FAQs
The RM/92020/JM/25 uses a 20 mm bore, 25 mm stroke, and an M5 port, aligning with common compact mounting standards while minimizing the required envelope. Its magnetic piston supports straightforward sensing integration with standard proximity or reed switches, reducing wiring complexity. For best results, verify mounting pattern compatibility with your existing adapters and confirm end-clip or flange mounting options in the datasheet.
Operating temperature range is from -5 to 80 °C (23 to 176 °F) and operating pressure is 1 to 10 bar (14 to 145 psi). These ranges support use in general automation environments, including light washdown where permissible by the exact variant. Always confirm the specific IP rating and environmental suitability for your application from the datasheet before deployment.
The integrated magnetic piston provides native compatibility with non-contact position sensors, enabling reliable end-of-stroke detection without external magnets or housings. This streamlines wiring and PLC or microcontroller integration, improves repeatability, and reduces risk of misdetection in high-cycle applications such as packaging lines or precision pick-and-place tasks.
Yes, its low-friction seals and non-corrodible construction support long service life in high-cycle environments typical of packaging lines. The anodised aluminium barrel and stainless steel piston rod resist wear and corrosion, respectively, while the compact geometry simplifies enclosure design in tight spaces. For full compliance in food-grade lines, confirm the exact material certifications and IP rating with the datasheet and supplier guidance.
