Norgren RT/57225/M/160 Roundline Cylinder Magnetic Piston
Part Number: RT/57225/M/160
Quick Summary
RT/57225/M/160 Roundline Cylinder is a compact, double-acting pneumatic actuator designed for precise part handling in automation lines. Space constraints and mounting rigidity often throttle throughput; this design saves about 20% space compared with standard ISO/VDMA lengths. Industry standards like CE conformity and IP-rated enclosures are commonly addressed in these builds, with SIL-ready options for safety circuits to support compliant integration. The cylinder uses low-friction seals and a robust double-crimped end cap, while a magnetic piston enables easy sensor integration for robust, scalable control. This combination delivers measurable business value through reduced footprint, extended service life, and simpler maintenance across modern factories.

The RT/57225/M/160 Roundline Cylinder uses a 25 mm bore and 160 mm stroke to deliver a compact footprint that supports density in small- to medium-sized automation cells, enabling tighter layouts and faster cycle times in pick-and-place and clamp applications. The low-friction, long-life seals reduce wear, meaning longer maintenance intervals and lower operating costs, even in high-cycle environments. A stainless steel barrel and a martensitic stainless steel piston rod provide corrosion resistance, extending service life in challenging environments and improving reliability in wash-down or outdoor installations. The standard magnetic piston simplifies sensor integration, facilitating easy position sensing for safe, closed-loop control without extra retrofits. Buffer cushioning minimizes impact, protecting workpieces and equipment while reducing vibration-induced wear. The range’s Rc1/8 port size, plus multiple mounting options (including UF universal piston rod mounting and swivel/clevis configurations), offer installation flexibility and faster retrofits across existing lines. Compatibility with Pneufit C fittings and tubing supports quick, leak-free plumbing, while the Roundline series ensures consistent performance with ISO/VDMA-driven systems. In practice, operators gain predictable repeatability, reduced downtime, and a lower total cost of ownership during lifecycle management.

FAQs
Begin by selecting compatible mounting hardware such as UF universal piston rod mounting or clevis/swivel options for 25 mm bore. Verify Rc1/8 port connections and use Pneufit C push-in fittings for leak-free plumbing. Ensure correct orientation to optimize stroke travel and sensor placement for the magnetic piston. Finally, confirm securing hardware and seals are clean and tight to maintain performance in high-cycle applications.
Key specs include 294 N theoretical force at 1–10 bar operating pressure and the -10 to 80 °C operating temperature range. The double-acting design with buffer cushioning reduces impact loads, improving lifecycle wear. The stainless steel barrel and piston rod resist corrosion, supporting longer service life in demanding environments. Plan for 20% space savings translating into higher cycle density and more predictable throughput.
Yes. The 25 mm bore and 160 mm stroke provide a compact yet capable actuator for small parts handling. The magnetic piston supports sensor feedback for reliable positioning, while the roundline geometry achieves space savings and easier cabinet layout. Its durable seals and stainless components enable consistent performance across multiple cycles, making it well-suited for high-speed packaging and similar assembly tasks.
Check for CE conformity and IP protection as part of your regulatory requirements, and confirm SIL-rated safety integration where applicable. Sensor-ready features with a magnetic piston simplify compliance with control-system safety protocols. Always verify that the specific installation and enclosure meet your plant’s standards, and consult the datasheet for exact certification statements and any available IP ratings for your configuration.
ROI is driven by space savings, reduced maintenance, and longer service life. The 20% footprint reduction enables denser line layouts and shorter wiring to reach destinations, lowering installation costs. Stainless steel components and long-life seals minimize replacement frequency, while magnetic sensing streamlines integration with existing control systems. Collectively, these factors reduce downtime and lifecycle costs in continuous operation environments.
