Norgren RM/960/250 Tie Rod Cylinder - Adjustable Cushioning
Part Number: RM/960/250
Quick Summary
Norgren RM/960/250 Tie Rod Cylinder is a robust pneumatic actuator for high-load linear motion in automated production lines. One common challenge is wear and misalignment that shorten cycle life and raise maintenance costs. The RM/960/250 mitigates these issues with an anodised aluminium barrel, martensitic stainless steel piston rod, and adjustable cushioning for controlled deceleration. In practice, this class of cylinder benefits from CE-safety alignment and reliable environmental protection to meet harsh factory conditions. With a 6 inch bore, 250 mm stroke, and a 2–10 bar operating window, installation is straightforward, and multiple mountings support quick integration. The design translates to higher uptime, lower replacement costs, and predictable, repeatable actuation for demanding automation tasks.

FAQs
The RM/960/250 supports an extensive range of mountings designed for quick, secure installation in existing frames. This includes compatibility with standard tie-rod configurations and multiple front, rear, and intermediary mounting styles to minimize misalignment and optimize stroke alignment in automated lines.
The cylinder delivers a theoretical force of 10887 N under rated conditions. Real-world performance depends on air supply pressure, bore friction, and cushioning settings. With adjustable cushioning, you can tune deceleration to maintain precision while protecting downstream components, yielding consistent cycle times and reduced wear.
Yes. The 6 inch bore and 250 mm stroke enable rapid actuation while the adjustable cushioning mitigates impact at end-of-stroke. Ensure supply pressure is kept within 2–10 bar and mountings minimize side loads to sustain high-speed performance and repeatability on packaging lines.
In practice, ensure adherence to CE safety guidelines and appropriate IP-rated environments for your application. The RM/960/250’s non-magnetic construction reduces interference with sensors, supporting reliable feedback. Pair it with suitable guarding and interlocks to meet plant safety requirements and maintain regulatory compliance.
Maintenance is supported by QM/960/00 service kits for RM/900-series cylinders, enabling field servicing of cushions, seals, and fittings. Regular inspection of ports and rod ends, along with scheduled replacement of consumables, helps sustain performance, reduces unexpected downtime, and extends the cylinder’s service life.
