FAQs
The RM/980/1675 offers an extensive range of mountings designed for robust alignment and versatility in industrial setups. The tie-rod design supports common mounting styles, and compatibility with standard RM/900 fittings simplifies integration across multi-axis systems. If your application requires a specific orientation or stroke end mounting, verify available configurations with the supplier or distributor before ordering.
This cylinder operates with compressed air between 2 and 10 bar and tolerates temperatures from -20 to 80 °C (-4 to 176 °F). These ranges suit a wide variety of production environments, from cold tooling cells to warm packaging lines, while maintaining consistent performance and cushioning characteristics.
Yes. With an 8 inch bore and a long 1675 mm stroke, this model provides substantial reach and force for extended travel tasks. Its adjustable cushioning helps manage deceleration and cycle timing, making it well-suited for conveyor transfers, part handling, and robot-assisted pick-and-place operations in demanding production lines.
The cylinder uses an anodised aluminium barrel for weight-saving and corrosion resistance, paired with a stainless steel (martensitic) piston rod for strength and durability. The non-magnetic construction minimizes interference in sensitive magnetic environments, contributing to longer service life in demanding plants.
Maintenance can be supported with service kits QM/980/00 for RM/900, 8" cylinders, which streamline part replacements and routine servicing. Regular checks on cushioning settings and port connections, combined with standard RM/900-series service kits, help maintain performance and minimize downtime during plant maintenance windows.
