Feature → Business Impact → Application: The RA/802125/M/200 uses a 125 mm bore and 200 mm stroke in a double-acting configuration, delivering a high theoretical force of 7363 N for robust positioning and gripping tasks. This translates to faster cycle times and improved throughput on packaging and automation lines, while maintaining precise end-position control in manufacturing cells. Feature → Business Impact → Application: Adaptive Cushioning System (ACS) provides controlled deceleration and impact reduction, protecting fragile components and extending cylinder life in high-cycle environments such as pick-and-place or conveyance systems. Feature → Business Impact → Application: Polyurethane seals deliver low friction, reducing energy consumption and wear, which lowers maintenance costs and improves energy efficiency in continuous operation zones. Feature → Business Impact → Application: Anodised aluminium barrel and martensitic stainless steel piston rod offer corrosion resistance and long-term durability in factory air, oil mist, and dust-prone environments, enhancing uptime in demanding environments like automotive assembly and material handling. Feature → Business Impact → Application: ISO 15552 compliance and standard mounting patterns enable straightforward retrofits and interchangeability with existing equipment, shortening installation times and reducing engineering effort when scaling lines or replacing worn cylinders. Feature → Business Impact → Application: Magnetic piston rod plus bracket-mountable switches provide easy integration with M/50 and related sensing solutions, enabling reliable feedback for PLC control and automation safety interlocks across OEM lines and service shops.

FAQs
Installation follows standard ISO 15552 mounting conventions with 125 mm bore cylinders and 289 mm length profiles. Mounting options include D2 rear clevis, front/rear flange mounts, and various clevis configurations to fit the QM/8125 family brackets. Ensure parallel alignment, clean interfaces, and proper bracket selection to maintain stroke accuracy and minimize side loads for a longer service life.
Key specs include a 125 mm bore, 200 mm stroke, 1–16 bar operating pressure, and a theoretical force of 7363 N. The Adaptive Cushioning System smooths deceleration, reducing impact and wear during frequent start–stop cycles. The combination of polyurethane seals and magnetic rod compatibility supports reliable, repeatable actuation essential for high-speed packaging and sorting applications.
Yes. The RA/802125/M/200 features a magnetic piston rod and is compatible with switch mounting brackets (for example M/50 and QM series). This enables reliable sensor feedback for PLC control, safety interlocks, and automation sequencing without requiring costly retrofits. Bracket-mounted switches can be added within the ISOLine family to fit existing control architectures.
Operating temperature ranges from -20 to 80 °C (-4 to 176 °F) and operating pressure from 1 to 16 bar (14 to 232 psi). The aluminium barrel is anodised for corrosion resistance, and the piston rod is martensitic stainless steel, offering robust durability in factory air, oil mist, and dust-prone environments. These features help ensure consistent performance in automotive, packaging, and general automation settings.
Long-life polyurethane seals minimize friction and wear, while ACS cushions reduce shock loads, collectively extending service intervals and reducing downtime. Adhering to clean compressed air supply and performing routine inspection of seals and end-caps will sustain actuation accuracy. The standard ISO 15552 footprint simplifies retrofits and replacements, lowering engineering time and total cost of ownership over the cylinder’s lifecycle.
