IMI Norgren RM/980/750 Pneumatic Cylinder - Cushioning
Part Number: RM/980/750
Quick Summary
RM/980/750 is a tie rod double-acting pneumatic cylinder for heavy-duty linear actuation in manufacturing lines. Engineers often struggle with reliability, mounting compatibility, and maintenance costs on long-cycle equipment. The design aligns with CE-compliant guidelines, IP-rated ruggedness, and SIL-based safety integration for regulated environments. This combination delivers predictable performance, reduces downtime, and lowers life-cycle costs in material handling, clamping, and press automation. The RM/980/750 offers broad mounting options and compatibility with RM/900 components, simplifying retrofit projects. Its anodised aluminium barrel and martensitic stainless piston rod deliver durability in tough environments, while adjustable cushioning reduces impact during cycles. With an 8 in bore, 750 mm stroke and 19417 N thrust, this unit handles demanding automation tasks reliably.

Feature: The 8 inch bore and 750 mm stroke deliver a theoretical thrust of 19,417 N, enabling high-load actuation in demanding cycles. Business impact: This configuration reduces the number of cycles required for heavy handling tasks and supports longer stroke travel without additional actuators. Application: ideal for material handling, clamping, and forming operations in automation lines. Feature: Tie rod double-acting design with a standard G3/4 port size provides robust mounting and reliable push-pull motion. Business impact: simplifies integration into existing pneumatic circuits and minimizes retrofit risk. Application: machine tending, pick-and-place, and press operations across manufacturing cells. Feature: Adjustable cushioning enables fine-tuning of approach and retraction speeds. Business impact: reduces impact forces, minimizes vibration, and extends component life in high-speed cycles. Application: precision clamping, stacking, and transfer applications where controlled deceleration matters. Feature: Non-magnetic construction supports sensor-rich environments and reduces magnetic interference near measurement devices. Business impact: preserves sensor accuracy and improves process reliability. Application: automated assembly lines with inline sensing and quality checks. Feature: Durable materials—anodised aluminium barrel and martensitic stainless piston rod—provide corrosion resistance and strength across a wide temperature range (-20 to 80 °C). Port size G3/4 and compatibility with RM/900 family increase configurability. Business impact: longer service life in harsh environments and easier sourcing of compatible spares. Application: outdoor or harsh indoor facilities requiring reliable performance. Feature: Wide compatibility and serviceability include extensive mounting options, the RM/900 range, and QM/980/00 service kits for quick field maintenance and easy retrofits. Business impact: minimizes downtime during maintenance and accelerates retrofit projects. Application: retrofit of legacy RM equipment and expansion of automations across production lines.

FAQs
The RM/980/750 supports an extensive range of mountings typical of the RM/900 Martonair family, enabling robust integration into existing frames and automation cells. When selecting a mount, consider stroke requirements, space constraints, and sensor positioning to ensure repeatable cycles and reduced setup time.
Operating temperature: -20 to 80 °C (-4 to 176 °F). Operating pressure: 2 to 10 bar (29 to 145 psi). Port size is G3/4, compatible with standard pneumatic hoses and fittings, simplifying installation and maintenance in typical factory environments.
Yes. The cylinder has a theoretical thrust of 19,417 N, combined with an 8" bore and 750 mm stroke, making it suitable for heavy-duty material handling, clamping, and stamping tasks in demanding automation lines.
Adjustable cushioning allows you to tailor deceleration at the end of stroke, reducing impact, minimizing vibration, and extending cylinder life in high-speed or high-cycle operations. This is particularly beneficial for sensitive downstream equipment and precision assembly steps.
Maintenance is supported by service compatibility with the RM/900 range and QM/980/00 service kits for RM/900, 8" cylinders. This enables quick field service, straightforward retrofits into existing RM systems, and minimized downtime during upgrades or replacements.
