Interchangeability through ISO 15552 standardization and a 125 mm bore translate into true interchangeability across the ISOLine family. This standardization minimizes spare parts variety, reduces changeover time, and supports quick swaps with existing brackets, fittings, and end-of-stroke cushions. The practical result is shorter downtime, lower inventory costs, and a smoother path to scaling automation across multiple production cells.Double-acting operation provides bidirectional actuation from a single air supply. This reduces system complexity, eliminates the need for secondary actuators, and enables compact layouts for pick-and-place or clamping tasks where space is limited and cycle rates are high.Adaptive Cushioning System (ACS) delivers smart deceleration at end-of-stroke, minimizing impact and vibration. The benefit is extended seal and rod life, fewer nuisance leaks, and more consistent positioning—crucial for high-speed lines where repeatability directly affects throughput and yield.Polyurethane seals lower friction and resist wear in demanding environments, maintaining performance through long duty cycles and temperature swings. The tighter seal minimizes leakage and stabilizes system pressure, contributing to energy efficiency and reliable actuation.Magnetic construction enables straightforward position sensing and easy switch mounting on the tie rods. Compatible with M/50 family sensors and bracket options, this design reduces wiring, speeds integration, and improves diagnostic visibility in automated cells.Durable materials and environmental tolerance support harsh industrial use. Anodised aluminium barrel and martensitic stainless steel piston rod resist corrosion, while the 1–16 bar range and -20 to 80 °C operating window cover diverse plants. The 125 mm bore paired with 80 mm stroke delivers a robust 7363 N theoretical force.

FAQs

RA/802125/M/80 supports multiple 125 mm bore mounting options such as rear clevis, front/rear flange, foot, and swivel/trunnion mounts. This standardization aligns with Norgren’s mounting catalog (QA/8125 and QM/8125 series), enabling quick, secure installation and consistent alignment across machines.
ACS provides adaptive deceleration at end-of-stroke, reducing impact, vibration, and seal wear. The result is smoother cycles, lower maintenance frequency, and higher repeatability in high-speed applications like packaging and automated assembly lines.
Yes. The RA/802125/M/80 is specified for 1 to 16 bar (14 to 232 psi) and operates under -20 to 80 °C, making it compatible with typical industrial environments and many external temperature variations without sacrificing performance.
Theoretical force is 7363 N at the nominal bore and stroke. Actual force will vary with supply pressure and speed, but this level supports demanding clamping, pushing, or positioning tasks with high repeatability, contributing to shorter cycle times and better part handling.
This cylinder supports Norgren’s switch/mounting ecosystem, including M/50 reed and solid-state switches and mounting brackets (such as QM/8125 series). Bracket-mounted switches and standard 12 mm push-in fittings simplify sensor integration and reduce wiring complexity for PLC-based control.
