Norgren RA/192125/M/20 ISO Compact Cylinder - ISO 21287
Part Number: RA/192125/M/20
Quick Summary
ISO compact cylinder RA/192125/M/20 delivers precise linear actuation for automated manufacturing lines. This compact solution reduces footprint while maintaining high force, simplifying integration in tight spaces. While engineers often contend with mounting constraints, this unit offers a flush-mount option for switches and a magnetic piston as standard to support reliable sensing. It conforms to ISO 21287, and is manufactured in Germany with robust materials to withstand demanding environments. For teams seeking predictable performance, the combination of buffer cushioning and long-life seals translates into lower maintenance and less unplanned downtime, while retaining compatibility with standard pneumatic systems and control architectures.

The RA/192125/M/20 is designed for efficiency and reliability in modern automation. Feature → Business Impact → Application: ISO 21287 conformance ensures consistent dimensional accuracy and interchangeability across vendor lines, reducing design time and spare parts complexity on packaging lines. This translates into faster line commissioning and easier serviceability in the field. Feature → Magnetic piston as standard → Improved switch integration and sensing reliability in high-cycle pick-and-place tasks, enabling tight control of position feedback and cycle timing in assembly equipment. Feature → Buffer cushioning → Smooth deceleration of the piston, lowering vibration transmission and extending actuator life in high-speed transfer applications. Feature → 125 mm bore and 20 mm stroke → Substantial theoretical force (7363 N) for robust actuation in clamping and material handling, with sufficient bite for consistent part handling. Feature → Stainless steel piston rod and anodised aluminium barrel → Enhanced wear resistance and corrosion protection for demanding environments, reducing maintenance intervals. Feature → G1/4 port and 1-10 bar operating pressure range → Broad compatibility with common pneumatic supply lines and existing manifold setups, enabling quick installation and scalable system design. Feature → -5 to 80 °C operating temperature → Reliable operation in typical factory climates and process environments, minimizing the risk of performance drift. These benefits collectively support measurable outcomes like higher uptime, reduced changeover time, and lower total cost of ownership in applications such as machine tending, clamping, and transfer mechanisms.

FAQs
This cylinder supports standard ISO 21287 mounting and a flush-mount switch option, with a G1/4 port and 125 mm bore. Plan space for the 20 mm stroke and verify mounting brackets align with ISO Compact profiles to ensure smooth installation and reliable sensing in high-cycle environments.
Key specs include 125 mm bore, 20 mm stroke, operating pressure 1 to 10 bar (15 to 145 psi), operating temperature -5 to 80 °C, and a theoretical force of 7363 N. The magnetic piston and buffer cushioning support precise, smooth motion across typical factory loads.
Yes. The combination of a high theoretical force, magnetic piston, and buffer cushioning makes it well-suited for pick-and-place and clamping tasks where repeatability and controlled deceleration are critical, even in compact configurations.
Compatibility hinges on ISO 21287 compliance, G1/4 port sizing, and a 125 mm bore. Ensure the system provides adequate air supply (1-10 bar) and that connected sensors and control hardware can handle magnetic piston actuation and flush-switch mounting.
Durable long-life seals with low-friction operation reduce wear and downtime, while buffer cushioning minimizes mechanical stress and vibration. These factors contribute to longer service intervals, lower maintenance costs, and higher line throughput in automated cells.
