Norgren RM/960/X/170 Pneumatic Cylinder - Adjustable Cushioning
Part Number: RM/960/X/170
Quick Summary
Norgren RM/960/X/170 is a double-acting pneumatic cylinder for heavy-duty linear motion on industrial lines. Operators often contend with limited mounting options, insufficient cushioning, and reliability challenges in rugged environments. Certification-wise, this family is designed to meet common industry standards for robust automation components; CE compliance and IP-rated protection are typical expectations for cylinders in this class. The RM/960/X/170 offers adjustable cushioning, a 6-inch bore, and a 170 mm stroke, enabling flexible integration and improved lifecycle costs. In practical terms, this translates to smoother operation, reduced impact on tooling, and easier sourcing through a familiar Norgren platform that supports lean maintenance programs.

Feature → Business Impact → Application: The 6 inch bore provides a high theoretical force (10887 N) for demanding actuation, enabling reliable motion with heavy loads across metalworking and material handling lines. This translates to fewer stops for part rework and higher overall line throughput in packaging and automation projects. Feature → Business Impact → Application: Adjustable cushioning minimizes impact and vibration at end-of-stroke, extending actuator life and protecting downstream tooling, ideal for precision pick-and-place and assembly cells where repeatability matters. Feature → Business Impact → Application: Non-magnetic construction reduces interference with sensitive sensors and measurement systems, improving inline quality control in electronics assembly and clean-room adjacent processes. Feature → Business Impact → Application: Stainless steel (martensitic) piston rod and anodised aluminium barrel resist corrosion and wear, lowering maintenance costs in washdown areas or high-dust environments. Feature → Business Impact → Application: G1/2 port size and an operating pressure range of 2–10 bar enable straightforward integration with standard plant air systems, reducing installation time and compatibility concerns on retrofit projects. Feature → Business Impact → Application: The RM/900-series range and Martonair lineage offer broad mounting options and compatibility with existing Norgren components, simplifying stocking and service kit sourcing (QM/960/00) for maintenance teams. Feature → Business Impact → Application: Adjustable cushioning plus robust tie-rod construction addresses common objections about misalignment or instability in long-stroke cylinders, delivering predictable performance in automated conveyors and material handling lines.

FAQs
The RM/960/X/170 uses a tie-rod, double-acting configuration with standard mounting interfaces compatible with the Martonair family. Typical installations include flange or clevis mountings, with various angle brackets to adapt to existing frames. Confirm bore and stroke compatibility with your machine’s tool path and ensure the mounting hardware matches the cylinder’s threaded ports and pass-through clearances for smooth operation.
This cylinder supports an operating pressure range of 2 to 10 bar (29 to 145 psi) and tolerates temperatures from -20 to 80 °C (-4 to 176 °F). These specs make it suitable for standard factory air systems and a broad spectrum of industrial environments, while allowing for stable performance in mixed-temperature operations.
Yes, it is designed for reliable actuation under demanding conditions, but the cushioning can be tuned to optimize motion profiles. Adjustable cushioning reduces impact forces at stroke ends, enabling smoother acceleration and deceleration, which helps prevent vibration-induced wear and improves cycle life in high-speed pick-and-place and packaging lines.
Norgren provides service kits for the RM/900 series (QM/960/00), including seals, cushions, and protective components to maintain performance and extend life. Regular inspection of the piston rod surface, seals, and cushioning settings is recommended, along with periodic checks of mounting hardware to preserve alignment and minimize end-of-stroke shock.
Ideal for heavy-duty linear actuation in process automation, packaging, and material handling, the cylinder’s 6" bore and 170 mm stroke support substantial throughput and precise movement. Its non-magnetic body and stainless rod favor sensor integration near automation checkpoints, while the G1/2 port and standard mounting options simplify retrofits and compatibility with existing plant air systems.
