FAQs
The RM/980/1100 offers an extensive range of mountings and a standard G3/4 port, allowing straightforward integration with common pneumatic manifolds and brackets. For installation, verify bore alignment with the frame, select appropriate mounting feet, and ensure supply pressure stays within 2–10 bar to maintain consistent stroke and force. Compatible with standard factory air lines and control valves, it minimizes custom fabrication and downtime.
At 2–10 bar, the cylinder delivers a high actuation force, with a theoretical maximum around 19,417 N for the 8" bore. The double-acting configuration provides robust push-pull motion, while adjustable cushioning helps control acceleration and deceleration. For best results, match speed and load profiles to the cushion setting and monitor temperature to stay within -20 to 80 °C.
Yes, the RM/980/1100 is designed for temperature ranges from -20 to 80 °C, making it suitable for cold-room or outdoor applications, provided lubrication and seals are chosen accordingly for low temperatures. With non-magnetic construction and a stainless steel piston rod, it also maintains performance near sensor arrays and magnetic fields commonly found in automated lines.
Certification details are not listed in the provided data. When purchasing, confirm CE conformity for European installations, any required IP ratings for dust and water ingress, and SIL compatibility if integrating with safety systems. Always reference the datasheet for the exact certification scope and validation under your specific application.
Expected benefits include longer service life from rugged anodised aluminium barrels and corrosion-resistant piston rods, reduced downtime due to adjustable cushioning that minimizes impact wear, and consistent performance across a wide operating window. These factors translate to lower maintenance costs, fewer replacement parts, and improved machine uptime in high-cycle production environments.
