One third the basic length of ISO/VDMA models translates to dramatic space savings and easier integration in tight automation cells. This compact footprint reduces enclosure size, simplifies guide rail routing, and can unlock new machine layouts where space is premium. In practice, engineers apply it to compact pick-and-place modules or end-effectors where stroke and line travel must fit within crowded dashboards. The 20 mm diameter with a 25 mm stroke delivers precise actuation in confined spaces, enabling repeatable positioning for small packaging lines and robotics tasks. Magnetic piston design enables straightforward sensing and full control-system versatility, reducing wiring complexity and accelerating deployment. Anodised aluminium barrel and stainless steel rod provide non-corrodible construction, boosting durability in harsh environments and lowering maintenance costs over time. Low-friction long-life seals minimize wear and energy losses, contributing to higher efficiency and longer service intervals. Port size is M5 with standard mounting compatibility, easing valve and manifold integration and supporting rapid retrofits to existing systems. Operating from 1 to 10 bar and tolerating -5 to 80 °C, the cylinder suits typical factory floors, while the 188 N theoretical force ensures reliable actuation for small to mid-size loads. As part of the RM/92000/M range, it offers a scalable solution that preserves a consistent interface for future line upgrades.

FAQs
The RM/92020/N2/25 excels in tight automation cells requiring precise linear motion, such as pick-and-place modules, small robotics end-effectors, and packaging line actuations. With a 20 mm diameter and 25 mm stroke, it delivers repeatable positioning in confined spaces. The magnetic piston supports easy sensor integration, while corrosion-resistant materials ensure longevity in demanding environments, reducing downtime and maintenance costs.
Installers should plan for the M5 port connection and standard mounting interfaces compatible with common pneumatics valves and manifolds. The compact length simplifies enclosure routing and alignment in retrofit projects. Consider crowding around guides and ensuring minimal side loads to preserve seal life. The one third length advantage can also simplify frame design when updating legacy lines.
Expect a theoretical force of 188 N and reliable double-acting actuation across a operating range of 1–10 bar and -5 to 80 °C. The unit uses low-friction seals for extended life, and the stainless steel rod plus anodised barrel deliver consistent performance even after many cycles. The design supports stable velocity and position control essential for precision automation tasks.
While the product data does not list specific certifications, selection for such cylinders typically considers CE for general safety and EMC compatibility, SIL considerations for safety-related controls in automation, and IP ratings for ingress protection in harsh environments. When sourcing, confirm with the supplier whether these certifications apply to the exact lot and configuration you intend to deploy.
