Norgren RM/980/700 Pneumatic Cylinder - 8in Bore
Part Number: RM/980/700
Quick Summary
The RM/980/700 pneumatic cylinder provides robust linear actuation for heavy industrial automation in manufacturing and packaging. Operators often contend with insufficient stroke and harsh deceleration, which slows cycles and increases wear; this unit delivers a long 700 mm stroke with adjustable cushioning to smooth every cycle. Typical industry certifications for this class include CE conformity and IP-rated variants, with some configurations addressing SIL safety in harsher environments. With a rugged anodised aluminium barrel, a stainless steel (martensitic) piston rod, and multiple mounting options, it offers reliable performance and straightforward integration into existing lines. The combination of long stroke, non-magnetic construction, and standardized porting supports efficient upgrades in modern factories.

FAQs
The RM/980/700 supports multiple mountings typical for long-stroke cylinders, including face, flange, and clevis configurations. Installation involves selecting a compatible mounting kit, connecting a standard G3/4 pneumatic supply, and aligning the rod end to your load path. The unit’s 8 inch bore and 700 mm stroke are compatible with common integrated guides, enabling straightforward retrofits into existing lines without major rework.
Key specifications are an 8 inch bore, 700 mm stroke, double acting operation, G3/4 port size, and a working pressure range of 2 to 10 bar. The operating temperature span is -20 to 80 °C (-4 to 176 °F). Theoretical force is approximately 19.4 kN, with an anodised aluminium barrel and martensitic stainless steel piston rod providing durability and strength.
This cylinder excels in heavy automation tasks requiring long reach and high force, such as packaging lines, press feeds, and long-stroke transfer systems. It is well-suited for environments where corrosion resistance and non-magnetic construction are advantageous. Avoid applications with temperatures or pressures outside the specified -20 to 80 °C and 2–10 bar range, or where magnetism is critical to process operations.
Certification visibility varies by configuration. Typical Norgren line equipment supports CE conformity and can be configured for IP-rated environments and SIL considerations depending on the broader system design. Always verify the exact variant and datasheet for your region, and consult your supplier for the specific certification scope of the RM/980/700 in your application.
Maintenance can be simplified with the QM/980/00 service kit, designed for RM/900 series cylinders, including the RM/980/700 family. The adjustable cushioning reduces impact wear, extending cycle life and reducing downtime. The combination of durable materials and standard porting speeds up replacement cycles and minimizes maintenance costs over the cylinder’s life, delivering a favorable return on investment in high-cycle environments.
