FAQs
The RM/980/180 offers an extensive range of mountings to fit diverse machine layouts. Its tie-rod construction supports common configurations such as flange, clevis, and custom brackets, enabling straightforward integration into existing automation cells without lengthy rework. This flexibility simplifies upgrades and future-proofing of line layouts.
The cylinder operates from -20 to 80 °C and at pressures from 2 to 10 bar. It uses a G3/4 port size, making it compatible with standard compressed air supply circuits. Ensure clean, dry air and proper filtration to maintain performance and extend service life in high-demand environments.
Yes. With an 8 inch bore and a theoretical force of 19,417 N, this double-acting cylinder handles heavy loads reliably. The adjustable cushioning reduces impact and rebound, delivering consistent stroke timing and reducing wear on downstream equipment—ideal for high-cycle packaging and material handling lines.
Service kits exist for the RM/900 family, including parts referenced as QM/980/00 for RM/900 series components. Compatibility should be verified for RM/980/180, but these kits help maintain seals, cushions, and wear components to minimize downtime during maintenance cycles.
Durability is enhanced by an anodised aluminium barrel, a martensitic stainless steel piston rod, and non-magnetic construction. These features resist corrosion, reduce magnetic interference with sensors, and support reliable performance in demanding industrial settings, lowering total cost of ownership over time.
