Norgren RM/960/320 Tie Rod Cylinder - 6" Bore
Part Number: RM/960/320
Quick Summary
RM/960/320 is a tie rod double-acting pneumatic cylinder designed for heavy-load actuation in automated manufacturing. Operators and integrators confront downtime from shock, misalignment, and wear, so reliability and serviceability matter. When sourcing, verify CE compliance, IP ratings for protection, and SIL suitability to meet safety and regulatory requirements. With a 6-inch bore, 320 mm stroke, adjustable cushioning, and non-magnetic construction, it delivers high thrust with repeatable cycles, enabling efficient material handling, clamping, and press actuations in harsh industrial environments.

Service kits for RM/900, 6"
The RM/960/320 delivers high theoretical thrust of 10887 N from a robust 6" bore, supporting heavy-load applications such as stamping, clamping, and material handling. This translates into fewer actuators in a line and faster cycle times, boosting overall production efficiency. Its double-acting design allows precise control in both extend and retract strokes, while adjustable cushioning minimizes impact, reduces component wear, and lowers maintenance costs in high-speed cycles. The anodised aluminium barrel resists corrosion, and the martensitic stainless steel piston rod offers strength with long service life, maintaining accurate positioning even in demanding environments. Non-magnetic construction ensures sensor compatibility where magnetic interference must be avoided. Extensive mounting options and the standard G1/2 port simplify installation and retrofit into existing automation, enhancing line integration and uptime. Service access is supported by the QM/960/00 kit, easing preventive maintenance and spare-part planning. This cylinder suits RM/900 lineage and Martonair series, delivering proven reliability and predictable performance in automation tasks.

FAQs
The RM/960/320 offers an extensive range of mounting options to fit diverse automation layouts. Users can deploy common tie rod configurations, end-of-stroke attachments, and compatible mounts designed for modular integration. This flexibility simplifies retrofits on existing lines and accelerates installation in new machines, reducing setup time and enabling consistent alignment across multiple cylinders.
Yes. With a theoretical force of 10887 N, the RM/960/320 is designed for demanding tasks such as stamping, clamping, and heavy-material handling. Ensure your system pressure stays within the 2–10 bar range and that the fixture is sized for the stroke and load to maximize performance and reliability in high-force cycles.
The cylinder operates on compressed air (medium) at 2–10 bar and covers a temperature range of -20 to 80 °C (-4 to 176 °F). This broad range makes it suitable for many industrial environments, including manufacturing floors with temperature fluctuations, while maintaining stable performance and repeatability.
Maintenance is supported by the QM/960/00 service kit for RM/900-series 6" cylinders, enabling planned preventive maintenance and quick part replacements. Regular servicing helps sustain seal integrity, cushion settings, and overall performance, reducing unexpected downtime and extending the life of the actuator within automation lines.
Adjustable cushioning minimizes impact in high-speed cycles, protecting machinery and improving component life in material handling, die-press, and transfer systems. Non-magnetic construction ensures compatibility with sensitive sensors and instrumentation in automation environments where magnetic interference could affect accuracy and control, making it ideal for robotics, pick-and-place, and complex assembly lines.
