FAQs
The RA/8320/M/400 supports multiple QM mounting options designed for 320 mm bore cylinders: A - Front or Rear Stud (QM/8320/35); UR - Universal Rear Eye (QM/8320/33); UF - Universal Piston Rod (QM/8320/32); BG - Front/Rear Flange (QM/8320/22); plus various specialized brackets. When selecting, match the mounting to your actuator direction, ensure clear stroke travel, and confirm compatibility with your machine frame to minimize misalignment and maintenance.
The cylinder provides a theoretical thrust of 48228 N and operates at 1–10 bar (15–145 psi). Real-world force depends on velocity, cushioning, and mounting geometry, so consult the datasheet for load ramping and ensure your air supply can sustain peak flow during rapid extensions or retractions.
Yes. With a 320 mm bore, 400 mm stroke, adjustable cushioning, and magnetic sensing options, the RA/8320/M/400 enables reliable high-load positioning and repeatable cycle times. Its robust construction and ISO compatibility minimize integration risk on palletizing conveyors and transfer lines, while interchangeability supports quick line changes and reduced spare-parts inventory.
The cylinder conforms to ISO 15552 and ISO 6431, with VDMA 24562 and NFE 49-003-1 guidelines. This ensures standardized dimensions, mounting, and fitment across vendors, simplifying part replacement, reducing engineering time, and improving compatibility with broader ISO-compliant automation systems.
Maintenance is supported by the QA/8320/00 service kits, covering PRA/802, RA/802, PRA/182, RA/182, or RA/8000 across 320 mm diameter cylinders, plus optional magnetic reed switch (QM/32/5). These components shorten repair times, extend service intervals, and lower total cost of ownership by enabling rapid field refreshes and consistent performance.
