The ISO 15552 standardization of the RA/8000/M family enables rapid cross-vendor interchangeability, cutting spare-parts inventory and reducing downtime during line changes. Engineers appreciate consistent mounting patterns, proven seals, and common porting across vendors, which shortens commissioning and improves predictability in control integration. In packaging, material handling, and automation lines, this translates to faster installation and reliable performance. With a 250 mm bore and 125 mm stroke, the cylinder delivers up to 29,436 N of theoretical force, supporting heavy clamping and long-stroke positioning without sacrificing speed. This capability is particularly valuable in high-throughput pick-and-place and tooling actions common in modern manufacturing. Adjustable cushioning provides controlled deceleration at end-of-stroke, minimizing shock to loads and adjacent equipment, while its magnetic piston enables straightforward position sensing and compatibility with reed-switch solutions for PLC interfacing. The durable anodised aluminium barrel paired with a martensitic stainless steel piston rod offers corrosion resistance and wear durability, reducing maintenance frequency in harsh environments. An extensive range of mountings—front/rear stud, flange, clevis, foot, and switch brackets—facilitates precise alignment and fast retrofits on 250 mm bore frames. Operating pressure of 1–10 bar and a temperature range of -10 to 80 C ensure compatibility with a wide array of pneumatic systems, valves, and control architectures across industries such as packaging, automation, and material handling.

FAQs

RA/8250/M/125 supports an extensive set of mountings including M/P19446 wide hinge, QM/8250/35 front/rear stud, QM/8250/32 universal piston rod, QM/8250/25 clevis, QM/8250/22 front/rear flange, QM/8250/21 foot mounting, and additional brackets for switches. This variety enables precise alignment with existing frames and simplifies retrofits without fabricating new mounts. Select the mounting based on stroke direction, load orientation, and available space to minimize setup time and maximize stroke accuracy.
The RA/8250/M/125 operates from 1–10 bar (15–145 psi) and withstands temperatures from -10 to 80 °C (14 to 176 °F). These ranges support most industrial pneumatic environments, enhancing reliability in packaging and material handling. Operating within these limits reduces wear on seals and cushions, leading to longer service life and lower maintenance costs over the cylinder’s lifecycle.
Yes. With a 250 mm bore, 125 mm stroke, adjustable cushioning, and magnetic piston compatibility, RA/8250/M/125 excels in high-cycle packaging and pick-and-place tasks. The robust construction and ISO standardization ensure consistent performance, repeatability, and compatibility with common control architectures, reducing cycle-time variability and downtime.
The cylinder conforms to ISO 15552, ISO 6431, VDMA 24562, and NFE 49-003-1, which guarantees cross-vendor interchangeability and reliable performance.
