Norgren RM/92025/M/140 Cylinder – 25mm, 140mm Magnetic
Part Number: RM/92025/M/140
Quick Summary
RM/92025/M/140 cylinder by Norgren is a compact double-acting pneumatic actuator for compact automation tasks. Engineers frequently battle space constraints and longer setup times in tight machine layouts, but this unit preserves stroke while dramatically reducing footprint. Certifications are not specified for this variant; in industrial pneumatics, CE marking and IP protection are commonly considered, and SIL capabilities are sometimes important for safety-critical functions. For many customers, the combination of a non-corrodible design and a magnet-equipped piston simplifies integration with sensors and control systems. This model delivers predictable performance, lower maintenance, and greater design flexibility in automation projects, helping protect uptime and reduce total cost of ownership.

Feature: The RM/92025/M/140 delivers a length that is substantially shorter than a comparable ISO/VDMA cylinder, enabling significant floor-space savings and easier mounting in crowded automation cells. Business impact: Higher density layouts, faster line changes, and reduced enclosure footprints translate to lower installation costs and faster ROI. Application: packaging lines and micro-robotic pick-and-place stations where every millimeter of space matters. Feature: Low-friction, long-life seal design minimizes wear and air consumption. Business impact: Reduced maintenance intervals and lower operating costs after deployment in high-cycle pneumatic actuators. Application: high-demand production lines requiring reliable cycling with tight tolerance control. Feature: Fully non-corrodible construction enhances durability in varied environments. Business impact: Increased uptime and longer service intervals in humid or harsh shop floors, supporting total-cost-of-ownership reductions. Application: general automation in environments where corrosion resistance is beneficial. Feature: Standard magnetic piston enables position sensing and easy integration with control systems. Business impact: Simplified wiring and robust feedback for PLCs, enabling precise end-of-stroke detection and improved process control. Application: sensor-enabled automation networks and automated assembly cells. Feature: Broad operating envelope and compact porting—M5 port, 25 mm bore, 140 mm stroke, 1–10 bar range. Business impact: Versatile installation across multiple lines with consistent actuation performance, reducing the need for custom manifolds. Application: compact actuators in control cabinets and inline machinery. Feature: No cushioning at the end of stroke keeps actuation simple and predictable. Business impact: Consistent response times and straightforward control logic, minimizing integration risk. Application: fast pick-and-place and precise positioning tasks. Feature: Robust materials—barrel from anodised aluminium alloy and piston rod from stainless steel (austenitic). Business impact: Strong mechanical integrity and resistance to wear, lowering maintenance costs. Application: general-purpose pneumatics in manufacturing and automation.

FAQs
The RM/92025/M/140 uses a 25 mm bore with M5 porting and is designed to integrate within the RM/92000/M family mounting schemes. It supports common pneumatic installation practices, enabling straightforward adapter and bracket use. Verify mounting hole spacing and clevis options against your fixture to ensure a secure, repeatable fit in existing lines.
The unit has a theoretical force of 295 N. It operates across a pressure range of 1 to 10 bar (14 to 145 psi). This broad range supports common factory air supplies while enabling you to optimize speed and force for your specific application without changing hardware.
Cushioning is not provided on this model. While no end-of-stroke cushioning is built-in, you can tailor actuation profiles through valve control and soft-start strategies in your control system. This keeps motion straightforward and reduces risk of rebound in fast cycle tasks such as pick-and-place.
Certifications are not listed for this variant. In typical industrial practice, you should confirm CE compliance and applicable IP ratings with the supplier, especially if the cylinder operates in washdown or harsh environments. For safety-critical automation, consider SIL-related safety schemes and ensure compatibility with your safety PLCs.
The magnetic piston supports reliable position sensing and easy feedback to PLCs and sensors, reducing wiring complexity and enabling precise control of stroke. This improves cycle accuracy, reduces scrap, and shortens commissioning time, contributing to a lower total cost of ownership over the product lifecycle.
