Part Number: RA/802125/M/320
Quick Summary
Norgren RA/802125/M/320 is a precision pneumatic cylinder for automated linear actuation in manufacturing cells. Engineers often struggle with wear, friction, and unpredictable cushioning that extend cycle times and cause downtime. It conforms to ISO 15552 (VDMA 24562; NFE 49-003-1) and uses a magnetic piston to enable reliable sensing in automation environments. The Adaptive Cushioning System, polyurethane seals, and anodised aluminium barrel deliver long life and stable operation under demanding cycles. Standardized porting and bracket-ready switches simplify installation, helping OEMs and maintenance teams reduce downtime and total cost of ownership.

The RA/802125/M/320 offers a 125 mm bore and 320 mm stroke for robust, repeatable actuation ideal for high‑throughput pick‑and‑place and clamping tasks. Its theoretical force of 7363 N supports demanding loads at typical 1–16 bar pressures, improving line throughput and reliability. ISO 15552 conformance with VDMA 24562 and NFE 49‑003‑1 ensures interchangeability and easy spare‑parts sourcing across brands, reducing engineering time on line upgrades. The Adaptive Cushioning System (ACS) minimizes end‑of‑stroke impact, protecting seals and extending service intervals in high‑speed or harsh environments. Polyurethane seals deliver low friction and long wear life, preserving cycle efficiency and lowering maintenance costs. The anodised aluminium barrel paired with a martensitic stainless steel piston rod provides corrosion resistance and durability in challenging lines. Bracket‑mounted switches on the tie rods simplify wiring and retrofit projects, while the G1/2 port and compact footprint ease installation in tight spaces. This cylinder is well suited for automated assembly cells, packaging lines, and machine‑tending applications.

FAQs
The RA/802125/M/320 features a 125 mm bore and 320 mm stroke, designed for compact, high‑repeatability linear actuation in automation lines. With a theoretical force of 7363 N, it accommodates medium‑to‑heavy loads across typical operating pressures (1–16 bar), enabling consistent performance across production cycles.
Yes. The cylinder conforms to ISO 15552 (VDMA 24562; NFE 49-003-1), ensuring interchangeability with other ISO standard cylinders. It uses a G1/2 port and a 125 mm bore with a 320 mm stroke, aligning with common industry practices for quick upgrades and spares compatibility.
ACS provides adaptive end‑of‑stroke damping that reduces impact loads, minimizes seal wear, and lowers vibration. The result is longer seal and rod life, steadier cycle times, and reduced maintenance needs, particularly in high‑speed applications or where frequent start‑stop cycles occur.
The cylinder supports bracket‑mounted switches on the tie rods, and Norgren offers a range of mountings and switch brackets (for example QM/8125 series) to simplify installation and wiring. This facilitates quick retrofits and straightforward integration with existing control systems.
Ideal for automated assembly, packaging, and machine tending where reliable, high‑cycle linear actuation is required. Benefits include improved line throughput, reduced downtime due to wear and end‑of‑stroke impacts, and lower maintenance costs thanks to long‑life seals and corrosion‑resistant components.
