Norgren RM/980/2400 Tie Rod Cylinder - 8 in bore
Part Number: RM/980/2400
Quick Summary
Norgren RM/980/2400 tie rod cylinder delivers rugged double-acting actuation for heavy-duty automation and material handling applications. Engineers often struggle with extended strokes that require reliable cushioning and consistent speed without overshoot. In industrial procurement, look for certifications such as CE marking for European compliance, IP ratings to withstand dust and moisture, and, where safety-critical, SIL compatibility in control architectures. This model's long-stroke capability and robust construction support cost-efficient installations, improving uptime and throughput in demanding systems.

Feature: 8 in bore provides high theoretical force for heavy loading scenarios. Impact: Enables single-cylinder solutions to replace multiple smaller actuators, reducing footprint and maintenance. Application: Large clamping and forging lines where maximum push force is required without compromising cycle time. Feature: 2400 mm stroke extends reach and travel distance. Impact: Minimizes the need for auxiliary cylinders or mechanical linkages, cutting installation complexity. Application: Long-stroke material handling, transfer systems, and automated assembly with generous stroke requirements. Feature: Adjustable cushioning ensures controlled deceleration. Impact: Reduces shock loads, extends seal life, and lowers maintenance costs. Application: High-duty cycle presses and pick-and-place cells where smooth stops protect tooling. Feature: Anodised aluminium barrel and martensitic stainless steel rod deliver corrosion resistance. Impact: Prolongs service intervals in humid or washdown environments, lowering total cost of ownership. Application: Food processing, automotive paint lines, and outdoor installations. Feature: G3/4 port size with compatible mounting options. Impact: Simplifies integration with standard compressed air lines and existing manifolds. Application: Retrofit projects and new installations across mixed plant layouts. Feature: Service kits QM/980/00 support ongoing maintenance. Impact: Quick parts replacement minimizes downtime and extends lifecycle. Application: Planned maintenance programs and spare-part inventories for RM/900 series.

FAQs
The RM/980/2400 uses a standard G3/4 port size and supports common tie-rod mounting configurations. For retrofit projects, ensure bore alignment with existing guides and select compatible end-mittings (feet, flanges, or clevis) to minimize misalignment. Using the adjustable cushioning helps tailor deceleration to your load profile, reducing vibration during installation and commissioning.
Key specs include 8 inch cylinder diameter, 2400 mm stroke, double-acting operation, and adjustable cushioning. It operates between 2 and 10 bar with a temperature range of -20 to 80 C. Theoretical force is 19417 N, enabling substantial load handling. The G3/4 port and non-magnetic construction support robust integration in demanding environments.
This cylinder excels in long-stroke applications and heavy lifting, with cushioning to protect tooling. For high-speed pick-and-place, assess cycle time and acceleration limits; the long stroke may constrain top speeds. In practice, pairing with matched sensors and a controlled air supply can optimize throughput while preserving component life.
Check the datasheet and regional requirements for CE marking and any industry-specific certifications. IP ratings and SIL compatibility are commonly relevant for pneumatic actuators in harsh or safety-critical environments. Always confirm the exact certification scope with your supplier to ensure compliance for your application and locale.
The QM/980/00 service kit provides replacement seals, cushions, and wear parts tailored for RM/900-series cylinders. Using the kit during planned maintenance reduces unexpected failures and downtime, preserves cylinder performance, and extends service intervals in high-cycle environments. Keeping spares on-hand accelerates repairs and maintains output quality.
