Norgren RA/192125/MX/50 ISO Compact – ISO 21287
Part Number: RA/192125/MX/50
Quick Summary
Norgren RA/192125/MX/50 is an ISO Compact double-acting cylinder that delivers reliable, precise linear motion for automated assembly and pick-and-place tasks. Engineers often wrestle with wear, high-friction seals, and inconsistent stroke life, leading to unplanned downtime. This model counters those challenges with low-friction, long-life seals, a standard magnetic piston, and durable cushioning for smooth starts and controlled deceleration. It conforms to ISO 21287, uses buffer cushioning, and offers robust performance across wide temperature and pressure ranges. For system integrators, the combination of a standard G1/4 port and compatibility with flush-mounted switches simplifies installation, reduces configuration time, and improves repeatability in pneumatic or automation workflows. In short, it supports reliable, scalable automation while keeping maintenance costs predictable with durable components.

With a 125 mm bore and 50 mm stroke, the RA/192125/MX/50 delivers a compact footprint without compromising stroke performance, enabling higher cycle density in tight automation cells and closer presenter tooling. This design reduces machine footprint, supports shorter cycle times, and improves throughput across automated lines. The standard magnetic piston enables precise position sensing and simplifies integration with non-contact switches, reducing setup time and calibration drift while improving repeatability in high-speed indexing. The low-friction, long-life seals minimize wear and extend service intervals, lowering total cost of ownership and enabling longer production runs between maintenance. Buffer cushioning provides smooth acceleration and controlled deceleration, reducing vibration transfer to downstream mechanisms and protecting attached equipment. ISO 21287 conformance ensures interchangeability with other ISO Compact actuators, while the rugged construction with an anodised aluminium barrel and martensitic stainless steel piston rod delivers durability in challenging environments. The G1/4 port, 125 mm bore, and 50 mm stroke align with common gripper and sensor configurations, reducing integration risk. Designed for environments from -5 to 80 °C and 1 to 10 bar, the cylinder is suitable for diverse plant conditions and end-of-line tooling applications, resulting in faster changeovers and more reliable automation.

FAQs
The RA/192125/MX/50 uses a standard G1/4 port and conforms to ISO 21287, ensuring broad compatibility with typical pneumatic integrators, fittings, and manifolds. Its 125 mm bore and 50 mm stroke fit many standard gripper and sensor configurations, simplifying plumbing, mounting, and control wiring. This makes it a reliable choice for retrofit projects and new lines alike, minimizing the need for bespoke adapters.
Key specs include a 125 mm bore, 50 mm stroke, and double-acting operation for push and pull motions. Theoretical force is 7363 N, with operating pressure from 1 to 10 bar and temperatures from -5 to 80 °C. The piston is magnetic, and cushioning is provided by buffer systems to smooth operation and extend component life in cycling applications.
Yes. The magnetic piston supports flush-mounted switches, enabling compact integration with minimal enclosure height. The ISO 21287 standard ensures compatibility with a wide range of actuators, sensors, and controllers. Plumbings and fittings are simplified by the G1/4 port, while the durable construction reduces downtime during maintenance windows.
The RA/192125/MX/50 is designed to conform with ISO 21287 for ISO Compact actuators, supporting interchangeability and standardized maintenance practices. The magnetic piston and buffer cushioning are designed to improve repeatability and cycle life in automated systems, contributing to predictable performance and easier certification documentation for end-user safety and quality programs.
The combination of long-life seals, low friction, and buffer cushioning reduces wear and maintenance frequency, lowering downtime costs. The cylinder’s durable materials—anodised aluminium barrel and martensitic stainless steel rod—support extended service intervals in demanding environments. These factors translate to faster changeovers, higher line efficiency, and lower total cost of ownership over the product’s lifecycle.
