FAQs
To install RM/980/2900, start by confirming mounting compatibility with standard RM/90x frames and available tie-rod hardware. Attach the cylinder using ISO mounting patterns, connect the G3/4 port to a clean, dry compressed-air supply within 2–10 bar, and set the adjustable cushioning to suit the stroke and load. Use the QM/980/00 service kit where applicable for routine maintenance and seals, ensuring proper lubrication and torque on mounting bolts to preserve alignment through the 2900 mm travel.
The cylinder provides a theoretical force of 19417 N at standard conditions. It operates from 2 to 10 bar (29–145 psi) and is designed for a temperature range of -20 to 80 °C (-4 to 176 °F). For best results, calculate load at mid-stroke and verify the mounting orientation to maximize force transfer while maintaining smooth, cushioned travel.
Yes. The 8" bore and 2900 mm stroke enable extended travel for large-part transfer, pick-and-place, and stamping applications. Double-acting operation provides precise retraction and extension, while adjustable cushioning reduces impact forces. This makes it well-suited for high-cycle material handling lines and tooling stations where reliable, long-stroke actuation is required.
The RM/980/2900 is CE-compliant, adhering to essential European safety and environmental requirements. While exact certification details may vary by installation, the unit’s construction uses a rugged anodised aluminium barrel and non-magnetic stainless steel rod to support compliance with general industry safety practices. For full certification scope, refer to the datasheet and supplier documentation.
Maintenance can be streamlined with the QM/980/00 service kits designed for RM/900-family cylinders, enabling seal replacements and routine overhauls without full disassembly. The combination of adjustable cushioning and robust materials reduces wear, contributing to longer service intervals and lower total cost of ownership in high-cycle automation environments.
