Norgren RM/980/J/125 Pneumatic Cylinder - Cushioning
Part Number: RM/980/J/125
Quick Summary
The Norgren RM/980/J/125 pneumatic cylinder delivers robust double-acting actuation for heavy-duty automation applications. Engineers often face downtime from insufficient cushioning and wear under high-cycle loads. Typical industry standards such as CE compliance and IP-rated configurations are expected for equipment in European and rugged environments. By aligning with the RM/900 range, this model leverages proven Martonair design and enhances reliability; adjustable cushioning and a corrosion-resistant, non-magnetic build support predictable motion, faster setup, and reduced maintenance across packaging, material handling, and automated assembly lines.

FAQs
The RM/980/J/125 is designed for versatile mounting and standard pneumatic connections, including the G3/4 port size that aligns with typical industrial manifolds. To integrate with an RM/900 system, select compatible mounting brackets and end caps that suit your specific application, ensuring the stroke, bore, and cushioning settings match your press, clamp, or transfer station. Verify that your supply pressure is within 2 to 10 bar and that your environment supports the operating temperature range of -20 to 80 °C for reliable performance.
The RM/980/J/125 produces a theoretical force of 19,417 N at the specified bore and stroke. It operates within a pressure range of 2 to 10 bar and a temperature range of -20 to 80 °C. These limits support high-load, continuous-duty cycles while maintaining controlled motion and repeatability in demanding automation tasks such as stamping, forming, and aggressive material handling.
Yes, the RM/980/J/125 is well-suited for high-speed packaging environments due to its robust 8 inch bore, 125 mm stroke, and adjustable cushioning that reduces impact forces at the end of stroke. This cushioning minimizes wear on seals and rods, extending service life and lowering maintenance frequency. For high-speed lines, optimize cushioning settings to balance deceleration with cycle timing and ensure repeatable positioning.
Service kits for RM/980/00 are available to support ongoing maintenance of RM/900-series cylinders, including seals, o-rings, and related consumables. Regular inspection of end caps, cushioning adjustments, and rod sealing helps preserve performance. Always refer to the QM/980/00 service kit documentation for recommended replacement intervals and compatible accessories to minimize downtime.
The RM/980/J/125 uses an anodised aluminium barrel and a stainless steel (martensitic) piston rod, delivering durability and corrosion resistance while maintaining non-magnetic characteristics. This combination minimizes magnetic interference with sensitive sensors and actuators in automated cells, improving measurement accuracy and compatibility with modern control systems in robotics, serialization, and handling applications.
