FAQs
Begin by selecting bracket mounting options compatible with 125 mm bore cylinders and ensure the switch mounting brackets (e.g., QM/8125 series) align with the tie rods. Use the G1/2 port for air supply and route sensor wiring to compatible M/50 switches. The ISOLine design enables straightforward bracket mounting on the cylinder body for repeatable sensing and quick field adjustments.
The cylinder features a 125 mm bore and 25 mm stroke, with a port size of G1/2. It operates at 1–16 bar and can withstand -20 to 80 °C. Theoretical force is 7363 N, and the unit uses a magnetic piston rod with ACS for smooth, controlled motion in demanding automation tasks.
Yes. The Adaptive Cushioning System reduces impact and vibration, extending seal life and reducing downtime. Its 125 mm bore, precise 25 mm stroke, and magnetic sensing compatibility support reliable, repeatable actuation in fast-paced packaging and assembly environments.
RA/802125/M/25 conforms to ISO 15552, with alignment to VDMA 24562 and NFE 49-003-1. This standardization ensures interchangeability, easier maintenance, and consistent performance across multiple brands and components used on automated lines.
ACS reduces end-of-stroke impact and noise, lowering mechanical wear and downtime. Polyurethane seals provide low friction and longer service life, improving energy efficiency and reducing replacement costs. Over a typical lifecycle, these features translate to lower maintenance frequency and higher overall line availability.
