Norgren RM/960/550 Tie Rod Cylinder - Non-magnetic
Part Number: RM/960/550
Quick Summary
RM/960/550 tie rod double-acting cylinder delivers robust linear actuation for heavy-duty automation on manufacturing lines. Engineers often struggle with insufficient stroke or mounting flexibility; this model addresses those pain points with a rugged, adaptable design. Certification details such as CE, SIL or IP ratings are not listed in the data; however, its anodised aluminium barrel, martensitic stainless steel rod, and adjustable cushioning support reliable cycles. With a 6" bore and 550 mm stroke, plus a broad range of mountings, it helps reduce downtime and boost production efficiency in pneumatic systems. Operating on compressed air at 2–10 bar, it offers a practical solution for a wide range of industrial actuation tasks.

Service kits for RM/900, 6"
The RM/960/550 uses a 6 inch bore to generate up to 10887 N of theoretical force, enabling high-load actuation for clamping, stamping, or part transfer. This translates into shorter cycle times and greater productivity on demanding lines. Adjustable cushioning reduces impact at end of stroke, minimizing vibration and wear while extending cylinder life. In practice, that means less maintenance and quieter operation in air-powered picker and placement systems. The anodised aluminium barrel and martensitic stainless steel piston rod provide corrosion resistance and durability in harsh environments. Combined with non-magnetic construction, this cylinder is suitable for proximity sensors and other magnetic-sensitive installations. A standard G1/2 port size simplifies integration with common pneumatic fittings and manifolds, reducing installation time and inventory complexity. The double-acting design ensures reliable bidirectional movement across multiple axes. Extensive RM/900 compatibility and a broad range of mountings support retrofits and scalable automation. Service kits for RM/900, 6" (QM/960/00) are available to simplify field maintenance and keep lines running.
