Large-bore performance translates to high force and fast cycles, enabling higher throughput while maintaining accuracy in complicated pick-and-place tasks. The adjustable cushioning reduces impact energy, extending cylinder life and protecting downstream machinery in packaging and handling lines. The double-acting tie-rod design provides precise stroke control and straightforward mounting, reducing setup time and installation costs on multi-axis automation cells. With an operating range of -20 to 80 °C and a 2 to 10 bar operating pressure window, these cylinders perform reliably across factory floors and semi-dusty environments, minimizing unplanned downtime. The 8" bore paired with a 270 mm stroke supports demanding motion profiles and longer strokes without compromising control. The anodised aluminium barrel and martensitic stainless steel piston rod deliver corrosion resistance and durable wear surfaces, enhancing longevity in demanding environments. Standard G3/4 port size aligns with common compressed air systems, while RM/900 compatibility and QM/980/00 service kits streamline spare parts and maintenance. Non-magnetic construction supports sensor integration in magnetic-field environments, improving automation reliability and system performance.

FAQs
The RM/980/270 is designed as a tie-rod, double-acting cylinder compatible with multiple mounting styles within the RM/900 family. It uses standard G3/4 ports and supports the RM/900-series mounting configurations, making it straightforward to integrate with existing automation cells. Always verify the exact mounting options in the latest datasheet to ensure optimal alignment and cycle accuracy.
Key specs include an 8 inch bore and a 270 mm stroke, G3/4 port size, and a 2 to 10 bar operating pressure range. The operating temperature is -20 to 80 °C, with a theoretical force around 19,417 N. The piston rod is stainless steel (martensitic), the barrel is anodised aluminium, and cushioning is adjustable for controlled deceleration.
Yes, the RM/980/270 is designed for rugged industrial use, with features such as adjustable cushioning to absorb impact, non-magnetic construction for sensor compatibility, and corrosion-resistant materials. For continuous, high-duty cycles, confirm your exact duty cycle against the datasheet and consider pairing with the QM/980/00 service kit to simplify maintenance.
Critical certifications commonly referenced for this class include CE marking and general IP-protection considerations for industrial pneumatic components. Always consult the official datasheet and regional compliance documents to confirm the exact certifications for your market and installation, especially for highly regulated environments or safety-critical applications.
Adjustable cushioning tunes the deceleration profile at the end of stroke, reducing shock, vibration, and mechanical wear. This improves repeatability and placement accuracy while extending cylinder life and reducing maintenance costs. In practice, optimized cushioning supports smoother cycles in packaging lines and improves performance in high-speed pick-and-place operations.
