Norgren RM/960/280 Pneumatic Cylinder - 6 in Bore
Part Number: RM/960/280
Quick Summary
Norgren RM/960/280 is a tie rod double-acting pneumatic cylinder engineered for high-load, long-stroke actuation in manufacturing and material handling. It addresses common pain points such as uneven motion, impact damage, and misalignment by delivering rugged, repeatable force across extended cycles. The design supports CE conformity and can be configured with optional safety and mounting accessories to meet varied plant requirements. With an anodised aluminium barrel, stainless steel piston rod, and adjustable cushioning, it delivers reliable performance in harsh factory environments. This solution aligns with the RM/900 range and the Martonair lineage, supporting scalable automation while reducing downtime and maintenance costs. In practice, engineers select this cylinder for precise positioning, clamping, and controlled end-of-stroke damping to boost line reliability and throughput.

FAQs
RM/960/280 supports standard mounting interfaces common to pneumatic cylinders, including centerline, flange, and foot configurations. The tie-rod design provides rigidity under load, reducing side loads on the rod and improving cycle accuracy. When selecting mounts, consider stroke clearance, load direction, and sensor placement to optimize alignment and reduce maintenance. Optional sensor-ready mounts may be available depending on the variant.
The cylinder operates from -20 to 80 °C (-4 to 176 °F) and is rated for 2 to 10 bar (29 to 145 psi) of compressed air. To maintain performance, use clean, dry air and ensure the supply pressure stays within the specified range. This combination supports reliable actuation in typical industrial environments while enabling consistent force across cycles.
With a 6 in bore and 280 mm stroke, RM/960/280 excels at high-load clamping, precise positioning, and controlled end-of-stroke damping on conveyors, transfer lines, and pick-and-place systems. The adjustable cushioning minimizes impact on downstream tooling, while the non-magnetic design reduces interference with nearby sensors and measurement devices in automation loops.
RM/960/280 can be configured for CE conformity in regions requiring safety compliance. IP ratings and SIL compatibility depend on the selected mounting, enclosure, and safety accessories. For specific certifications, consult the datasheet and configure options to align with your plant’s regulatory requirements, ensuring full compliance in your application.
Routine maintenance includes inspecting seals, cushions, and end-of-stroke components, as well as verifying cushioning adjustments. Service kits QM/960/00 support RM/900 series components to simplify upkeep. Maintain clean air supply, monitor for wear on the anodised barrel and stainless rod, and schedule periodic inspections to minimize downtime and extend cylinder life.
