Norgren RM/980/1950 Tie Rod Cylinder - 8 in Bore
Part Number: RM/980/1950
Quick Summary
RM/980/1950 is a tie-rod double-acting cylinder used for heavy-duty actuation in industrial automation. When production lines demand long reach and repeatable motion, cushioning inconsistencies and misalignment threaten cycle times. Key features such as adjustable cushioning, a rugged anodised barrel, and a stainless steel piston rod support reliable operation in harsh environments. Industry standards and safety considerations guide design, with CE-like compliance and IP-related protection commonly addressed in this family; always verify on the datasheet. For businesses, the combination of long stroke, robust construction, and compatible RM/900 range reduces lifecycle costs and speeds up system integration. These advantages translate into measurable uptime and lower maintenance costs across manufacturing lines.

Service kits for RM/900, 8"
Feature: The 8 inch bore and 1950 mm stroke deliver substantial thrust and reach for heavy workload handling, reducing the need for multiple actuators on large automation lines. Business Impact: Longer stroke and higher force translate to fewer cycles and faster material transfer in high-cycle environments, improving overall line throughput. Application: Ideal for large-part handling, automated transfer systems, and gantry-style moves where mounting space is a premium. Feature: Double-acting operation with adjustable cushioning provides smooth, controlled motion through end positions, reducing lag and mechanical shock. Business Impact: Cushioning minimizes wear on guides, seals, and mounting hardware, extending service life and lowering total cost of ownership. Application: Particularly valuable in precision assembly, automated pick-and-place cells, and machine tending where repeatable cycle timing is critical. Feature: Anodised aluminium barrel and martensitic stainless steel piston rod deliver exceptional corrosion resistance and durability in demanding environments. Business Impact: Non-magnetic construction minimizes interference with nearby sensors and control systems, enhancing measurement accuracy and process stability. Application: Suitable for facilities exposed to vibration, lubricants, or coolant exposure, improving uptime and reducing maintenance frequency. Feature: Port size G3/4 and RM/900 family compatibility enable straightforward integration with standard plant air systems, fittings, and mounting patterns used in industry. Business Impact: Simplifies installation, reduces custom fabrication, and supports rapid scaling across multiple lines while preserving spare-part commonality. Application: Retrofit projects and new installations that benefit from a consistent pneumatic interface and predictable lead times. Feature: Operating range -20 to 80 C and 2 to 10 bar accommodates diverse factory conditions while maintaining reliable actuation. Business Impact: Consistent performance across temperature and pressure variations minimizes downtime and delivers stable quality. Application: Suitable for manufacturing, cold storage, hot production areas, and heavy-duty automation tasks requiring a rugged pneumatic cylinder.

FAQs
RM/980/1950 supports extensive mounting options and standard RM/900 interfaces, which simplifies installation in existing lines. Ensure port size G3/4 connections are compatible with your valve manifolds and that support brackets clear the 8 inch bore to prevent side loading. Use the service kit QM/980/00 for routine seal replacements and cushion calibration.
With a theoretical force of 19417 N at recommended pressures, the cylinder can move heavy loads in a single stroke. Operates at 2–10 bar and -20 to 80 C, providing consistent actuation across most factory environments. Cushioning adjustment allows tuning for smooth acceleration and deceleration, which reduces impact on guides and sensors.
Yes, its long stroke and high thrust make it well-suited for material handling, transfer systems, and light to medium-duty press applications. The non-magnetic construction minimizes interference with nearby sensors, and the anodised barrel resists wear. Ensure correct mounting and lubrication; the RM/900 family compatibility helps standardize across multiple lines. For demanding cycles, configure cushioning accordingly.
Exact certifications should be confirmed on the product data sheet; while general Norgren products in this family are designed with safety and quality in mind, customers typically verify CE compliance and any IP-related protection from the datasheet or procurement documentation. Review installation and safety requirements before deployment to ensure regulatory alignment.
With routine maintenance using the QM/980/00 service kits, downtime is minimized as seals and cushions are replaced before wear affects performance. The cylinder’s robust materials and adjustable cushioning enhance life in harsh lines, translating to fewer spare parts and longer intervals between servicing. Higher throughput and reduced cycle times from the long stroke also contribute to a favorable ROI.
