FAQs
The RM/950/650 supports an extensive range of mountings to fit multiple orientations and load directions. Engineers typically choose through-shaft, clevis, foot, or flange configurations depending on stroke requirements and misalignment tolerance. When selecting mounts, consider dynamic loads, lubrication access, and maintenance ease to maximize uptime and minimize misalignment-induced wear over the cylinder’s life.
Operating pressure ranges from 2 to 10 bar (29 to 145 psi) with compressed air as the medium. Operating temperatures span -20 to 80 °C (-4 to 176 °F). These specs support versatile deployment in many industrial environments, while the G1/2 port size simplifies integration with standard plant air systems and reduces piping complexity.
Yes. The cylinder offers a theoretical force of 7600 N, enabling robust actuation for demanding tasks such as heavy clamping, pressing, and substantial material handling. Ensure your system pressure stays within the 2–10 bar range and size the control elements to accommodate the load profile, cycle rate, and desired speed for reliable operation.
Plan for robust mounting with the available 5 inch bore cylinder and adjustable cushioning to absorb impact. Verify alignment to minimize side loads, select compatible mounting hardware, and ensure easy access for maintenance. The non-magnetic construction helps in magnetic-sensitive environments, and the G1/2 port supports straightforward piping and filtration integration.
Service kits are available under QM/950/00 for RM/900 series, including RM/950/00 offerings for pneumatic maintenance. For ongoing maintenance, refer to the RM900 datasheet linked with Norgren Martonair products, and follow component-specified lubrication and inspection intervals to sustain performance and extend service life.
