RM/960/370 Norgren Pneumatic Cylinder - Adjustable Cushioning
Part Number: RM/960/370
Quick Summary
RM/960/370 is a high-capacity double-acting pneumatic cylinder designed for precise linear actuation in automation and material handling. In busy production lines, inconsistent cushioning and wear can cause misalignment and unexpected downtime; this cylinder mitigates those issues with adjustable cushioning and a rugged, corrosion-resistant build. For safety-critical implementations, verify CE conformity and assess any required IP ratings or SIL integrations; these certifications are common in industrial pneumatic systems and help ensure compliance in regulated environments. Users gain performance, reliability, and predictable maintenance windows when integrating the RM/900 family into packaging, automotive, and general manufacturing lines while leveraging compatibility with the Martonair RM range and available service kits.

FAQs
The RM/960/370 supports common RM/900 family mounting configurations, including flange, clevis, and integral mounts. Selecting the right mount improves alignment and minimizes bending moments, reducing wear. For serviceability, ensure mounting provisions accommodate easy access to diagnostic ports and seals; when in doubt, refer to the RM/900 compatibility guidelines and use the QM/960/00 service kits for maintenance.
The cylinder delivers up to 10887 N of theoretical force at the 6 inch bore with a 370 mm stroke. Operate within the 2 to 10 bar (29 to 145 psi) range to balance speed and load, and ensure the supply is clean and dry to maintain seal longevity. For high-cycle applications, verify actual cycle life under your specific load profile.
Yes, with double-acting operation and adjustable cushioning, RM/960/370 supports rapid, controlled actuation while limiting impact at stroke ends. This reduces fixture wear and downtime for high-cycle applications such as packaging and transfer lines. Ensure compatible mounting and proper lubrication, and plan maintenance with RM/900-series service kits to sustain performance over time.
Key considerations include CE conformity for general safety compliance and applicable IP or environmental standards depending on the installation. For safety-critical or regulated environments, verify SIL-related safety requirements with your system integrator and confirm that the chosen configuration meets all local electrical and mechanical standards. Certification needs vary by market, so confirm with the supplier before procurement.
To maximize uptime, use RM/900-compatible service components and the QM/960/00 service kits designed for RM/960 and RM/900 series cylinders. Regularly inspect seals, mounting hardware, and cushioning elements, and replace wear parts according to operating conditions. Proactive maintenance reduces leaks, maintains actuation precision, and extends service life across multi-shift production environments.
