Norgren RM/980/450 Tie Rod Cylinder - Adjustable Cushioning
Part Number: RM/980/450
Quick Summary
Norgren RM/980/450 tie rod cylinder delivers high-force, linear actuation for heavy automation in manufacturing and packaging. In demanding lines, varied stroke and wear lead to downtime; this cylinder offers rugged reliability to minimize unplanned stops. While CE compliance and industry standards apply across the RM/900 Martonair range, verify exact certifications for your application. This solution pairs with compressed air systems and offers long service life with adjustable cushioning, enhancing efficiency and bottom-line value. Designed for tie-rod mounting, it supports easy alignment and quick replacement, with an anodised aluminium barrel and martensitic stainless steel piston rod for corrosion resistance. Operating range accommodates 2 to 10 bar and -20 to 80 °C, making it suitable for a broad spectrum of manufacturing environments.

Feature: Tie rod double-acting design with an 8 inch bore and 450 mm stroke enables robust, high-force actuation for demanding cycles. Theoretical force of 19,417 N supports fast, precise movements in tooling, stamping, and transfer duties, reducing cycle times and consolidating multiple actions into a single unit. This configuration suits large automation cells and retrofit projects where reliable stroke and stroke-to-load balance are critical. Feature: Adjustable cushioning provides tailored deceleration and end-stop protection. By damping impact and controlling overshoot, it extends cylinder life, reduces vibration transmission, and improves repeatability in high-speed clamping and part-placing operations. End-users benefit from smoother start/stop profiles, fewer misfeeds, and lower maintenance costs in automated assembly lines. Feature: Premium build materials deliver durability in harsh environments. The anodised aluminium barrel resists corrosion while remaining lightweight, and the martensitic stainless steel piston rod offers strength without compromising precision. Non-magnetic construction is advantageous in magnetic-sensitive processes, preventing interference in sensors and equipment misreads during high-load positioning tasks. Feature: Installation flexibility and cross-compatibility with RM/900 range. G3/4 porting and tie-rod mounting simplify plumbing and alignment, enabling quick retrofits into existing lines and easy on-site adjustments. Extensive mounting options and standardised interfaces reduce engineering time, helping you meet tight project timelines while maintaining alignment accuracy across multiple cylinders in a system. Feature: Serviceability and lifecycle support. The RM/980/450 is complemented by dedicated service kits QM/980/00 and compatible RM/900 components, enabling fast field maintenance and predictable spare parts planning. Together with a robust design and long service life, this translates to improved uptime, reduced total cost of ownership, and consistent performance in continuous-operation manufacturing environments.

FAQs
For installation, plan tie-rod mounting locations that provide straight-line motion and easy alignment. Use the G3/4 porting with compatible fittings, and verify mounting pattern compatibility with the RM/900 series. Ensure adequate enclosure and clearance for the 8" bore and 450 mm stroke, and allow space for maintenance access and service kit replacements.
The RM/980/450 features an 8 inch bore, 450 mm stroke, and a theoretical force of 19,417 N. Operating pressure ranges from 2 to 10 bar (29 to 145 psi), with a temperature range of -20 to 80 °C. The port size is G3/4, and the cylinder is double-acting with adjustable cushioning for controlled deceleration.
Yes. The 8 in bore and 450 mm stroke combination supports high-load, high-cycle routines typical in tooling, clamping, and transfer tasks. Adjustable cushioning minimizes impact, reducing wear and downtime. The anodised aluminium barrel and martensitic stainless steel rod enhance durability in demanding environments, contributing to predictable cycle times and longer service life.
Certification details can vary by region and application. While RM/900/Martonair products commonly align with industry standards and CE considerations, always verify the exact certification status for your installation with the datasheet and supplier. The RM/980/450 is compatible with RM/900 components and service kits, which supports standard compliance workflows and retrofit planning.
Maintenance is supported by the QM/980/00 service kit and RM/900-series components for field replacement and quick service. Regular inspection of the piston rod, cushioning adjustments, and port fittings helps sustain performance. Access to official datasheets and technical support from IMI Norgren ensures up-to-date guidance and spare parts planning.
