Norgren RM/950/80 Tie Rod Cylinder - Double Acting
Part Number: RM/950/80
Quick Summary
Norgren RM/950/80 is a tie rod double-acting pneumatic cylinder designed for reliable linear actuation in automated manufacturing and handling. Engineers often struggle with harsh stops and inconsistent return speeds due to fixed cushioning, which this model mitigates with adjustable cushioning. The design aligns with common industry certifications and safety practices, including CE compliance and SIL-ready safety integrations where required. For engineers, the RM/950/80 delivers robust actuation with predictable lifecycle costs within modern pneumatics and automation systems. Its rugged construction and compatibility with standard mounting options helps reduce downtime and maintenance across high-cycle production lines.

FAQs
The RM/950/80 uses standard tie-rod mounting patterns compatible with Norgren RM/900 series end caps and common industrial mounting brackets. It supports a range of fixed and adjustable mountings, enabling straightforward integration with existing frames and clevis/linkage configurations. Always verify hole spacing and load orientation to ensure optimal performance.
The RM/950/80 is designed for compressed air with an operating pressure range of 2 to 10 bar (29 to 145 psi) and operating temperatures from -20 to 80 °C (-4 to 176 °F). These limits support versatile use in standard factory environments while maintaining actuator performance and longevity.
Yes, when equipped with adjustable cushioning. The 5 inch bore and 80 mm stroke deliver substantial force with controlled deceleration, reducing impact wear. For high-cycle use, ensure compatible mounting, correct lubrication (per system requirements), and periodic service kit checks to maintain consistent cycle times and reliability.
Industry-standard certifications are typically available depending on configuration and regional requirements. The RM/950/80 is designed to align with common safety and quality practices, including CE-compliant configurations, with SIL-ready safety integrations where applicable. For specific certification details, consult the regional product spec sheet and your authorized Norgren distributor.
Service kits for RM/900, 5" configurations are available under QM/950/00. These kits simplify maintenance by providing seals, cushions, and adapters tailored to the RM/900 family.
