With a 160 mm bore and a 250 mm stroke, the RA/8160/M/250 delivers substantial push and pull force within a compact footprint. This translates to higher cycle throughput and improved control in tight automation cells, such as packaging and assembly stations. The 1 to 16 bar operating range accommodates most factory air supplies, reducing the need for specialized pressure conditioning and improving overall system reliability. Theoretical force of 12064 N enables consistent positioning even under dynamic loads, supporting accurate pick-and-place or press operations while maintaining energy efficiency. The stainless steel piston rod and anodised aluminium barrel provide corrosion resistance and long service life in demanding environments, lowering maintenance frequency and total cost of ownership. Adjustable cushioning minimizes impact energy and vibration, extending life for both the actuator and attached tooling, while enhancing operator safety. The G3/4 port size and ISO 15552 standard ensure easy compatibility with existing valve manifolds and mounting rails; a wide array of mountings, including front/rear studs, clevis, swivels, and feet, simplify installation and reduce commissioning time. Built-in magnetic sensing enables straightforward home and position feedback for control systems, improving automation reliability. The RA/8000/M range compatibility supports scalable upgrades across lines without sacrificing performance, making this cylinder a future-proof choice for growing operations.

FAQs
The RA/8160/M/250 supports a broad set of mountings aligned with the ISO/VDMA cylinder ecosystem, including front or rear stud mounting, swivel hinge, universal rear eye, and clevis configurations. The Mountings group lists compatible codes such as M/P19938 (narrow hinge SS), M/P19679 (wide hinge), QM/8160 series (front/rear stud), and QA/8160 family options to simplify integration on 160 mm bore actuators.
This cylinder runs from 1 to 16 bar (15 to 232 psi) and operates from -10 to 80 °C (14 to 176 °F). These ranges cover typical factory air supplies and a broad set of environmental conditions, enabling reliable performance in standard automation environments without special cooling or conditioning.
Yes. The piston rod is stainless steel (martensitic) and magnetic, enabling simple integration with reed switches or magnetic sensors for position feedback. This supports straightforward implementation of closed-loop control and safe stop zones in automated lines.
The RA/8160/M/250 conforms to ISO 15552 and ISO 6431 standards, with alignment to VDMA 24562 and NFE 49-003-1. This standardization guarantees interchangeability with other ISO/VDMA actuators, easier spares management, and predictable performance across multiple supplier configurations.
Maintenance focuses on the adjustable cushioning, magnetic sensing, and robust materials. Service kits are available for compatible PRA/802, RA/802, PRA/182, RA/182, and RA/8000 families, with QA/8160D/00 specifically referenced for 160 mm diameter units. Regular inspection of seals, cushioning setting, and rod guidance minimizes wear, while modular mountings and standard ports simplify field servicing and part replacements.
