Norgren RM/980/50 Tie Rod Cylinder - Adjustable Cushioning
Part Number: RM/980/50
Quick Summary
RM/980/50 is a tie rod double-acting pneumatic cylinder used for high-force actuation in heavy-duty automation. Operators often contend with limited bore options and inconsistent cushioning that slow cycles and accelerate wear. Designed for rugged factories, this model supports reliable operation in harsh environments, aided by adjustable cushioning and a stainless steel piston rod. For procurement teams, the rugged aluminium barrel, non-magnetic construction, and versatile mountings translate to lower maintenance, longer service life, and faster installation in scalable automation projects.

Service kits for RM/900, 8"
The RM/980/50 delivers an 8 inch bore in a tie-rod configuration, enabling high theoretical force for demanding tasks while maintaining a compact footprint. This configuration reduces cycle time and improves handling accuracy in stamping and transfer applications, directly impacting overall line throughput. Adjustable cushioning lets you tailor deceleration to the load, reducing shock, vibration, and component wear, which lowers replacement costs and extends cylinder life. G3/4 port size supports common plumbing and quick-fit fittings, simplifying installation and maintenance across retrofit programs. The stainless steel (martensitic) piston rod resists wear and corrosion, ensuring smoother operation in environments with potential contaminants. The anodised aluminium barrel adds strength without excess weight, enhancing mounting stability and vibration resistance. This cylinder integrates with standard mounting options across the RM/900 range, enabling plug-and-play upgrades in existing lines and reducing engineering time. Service kits QM/980/00 support quick maintenance for RM/900 class units, helping minimize downtime during scheduled overhauls.
