Norgren RM/92025/N4/70 Compact Pneumatic Cylinder - 70mm
Part Number: RM/92025/N4/70
Quick Summary
The RM/92025/N4/70 is a compact double-acting pneumatic cylinder for precise linear actuation in automation. In space-constrained lines, engineers frequently battle footprint, wear, and sensor integration, making compact yet capable actuators like this essential. The design aligns with industry standards such as CE conformity, robust IP-rated options, and SIL-compatible safety considerations where applicable. With a magnetic piston, corrosion-resistant components, and a low-friction seal design, it delivers reliable performance and reduced maintenance. As a result, OEMs and maintenance teams gain predictable cycle life, faster ROI, and simpler sensor compatibility for automation tasks such as pick-and-place.

One of the standout features is its compact length: at roughly one third the basic length of a corresponding ISO/VDMA model, RM/92025/N4/70 frees valuable space on crowded automation cells. The 25 mm bore and 70 mm stroke deliver a practical balance between stroke travel and compact form, enabling tighter couplings with grippers, slides, and end-of-arm tooling. This makes it an attractive choice for packaging lines, pick-and-place, and robotic pick stations. Low friction, long life seal design reduces wear across high-cycle applications, translating into lower maintenance costs and less downtime. The combination of durable seals and a magnet-enabled piston enhances repeatability and sensor compatibility, even after thousands of cycles. In practice, operators see steadier actuation, consistent speeds, and fewer adjustments during line changes, which matters for pace and throughput in manufacturing environments. Fully non-corrodible construction supports reliability in challenging environments. Anodised aluminium alloy for the barrel resists corrosion, while a stainless steel piston rod provides strong, consistent performance under repeated cycling. This corrosion resistance is particularly beneficial in humid or wash-down areas, where external assets often experience life-cycle degradation. The result is longer service intervals and lower replacement risk. The integrated magnetic piston enables straightforward position sensing and control system integration without additional hardware. This supports easy adoption with existing PLCs, sensors, and Industry 4.0 architectures. The cylinder also aligns with a rugged magnetic design that improves repeatability and accuracy in short-stroke actuation, helping engineers meet tight tolerances in automated assembly and handling tasks. Ported for M5 air supply and a 25 mm bore, RM/92025/N4/70 is compatible with a wide range of valve manifolds and fittings across the RM/92000/M family. With no internal cushioning, users may opt for external dampers or application-specific stop methods to tailor impact and sound. The model’s specifications, including 1–10 bar operation and 295 N thrust, support fast, reliable actuation in demanding lines.

FAQs
When deploying RM/92025/N4/70, ensure mounting is compatible with a 25 mm bore and the M5 port size, selecting a mounting style that accommodates the short 70 mm stroke. Plan for magnetic sensing integration using the piston position feedback, and verify that the surrounding brackets and guides support the compact footprint. Consider external dampers if your application requires soft stops to minimize impact.
The cylinder operates from 1 to 10 bar (14 to 145 psi) and is rated for temperatures from -5 to 80 °C (-23 to 176 °F). This makes it suitable for most standard factory floors and mild wash-down environments. For extreme cycles or higher humidity areas, confirm additional protections or coatings on the barrel and ensure compatible valve manifolds to manage rapid cycling and heat buildup.
Yes, thanks to fully non-corrodible design features. The barrel uses an anodised aluminium alloy, while the piston rod is stainless steel (austenitic), delivering robust corrosion resistance in humid or wash-down environments. This construction reduces life-cycle degradation and lowers replacement risk, supporting longer intervals between maintenance in demanding manufacturing lines.
The RM/92025/N4/70 includes a magnetic piston, enabling straightforward position sensing and easy integration with PLCs and existing sensors. This supports Industry 4.0, with minimal additional hardware required. The actuator is compatible with the RM/92000/M tooling family, enabling quick deployment alongside established valve manifolds and control schemes.
Ideal for space-constrained pick-and-place, packaging lines, and automated handling where a small footprint is essential. The 25 mm bore and 70 mm stroke provide enough travel for short linear motions, while the magnetic piston supports reliable feedback for precision control. Its corrosion resistance and low-friction seals help maintain throughput with reduced downtime in high-cycle environments.
