Norgren RT/57320/M/25 Roundline Cylinder - Magnetic
Part Number: RT/57320/M/25
Quick Summary
Norgren RT/57320/M/25 Roundline single acting pneumatic cylinder is a compact actuator designed for precise linear motion in automation tasks. In tight control panels and limited-space cells, space efficiency and reliable actuation are critical, and this model directly addresses those challenges with a 20 mm bore and a 25 mm stroke. While typical buyers look for CE conformity, IP ratings and SIL compatibility in pneumatic systems, verify the exact certification levels in the official datasheet for your application. The combination of buffer cushioning, stainless steel components, and a magnetic piston delivers dependable performance, reducing cycle times and maintenance downtime. This cylinder also aligns with broader automation goals by enabling straightforward installation and robust system integration for scalable manufacturing lines.

Feature → Business Impact → Application: The RT/57320/M/25 uses a 20 mm bore and 25 mm stroke to deliver a compact footprint, enabling space-saving placements in small automation cells and tight fixture setups. This directly translates to higher machine density and reduced equipment footprint on production lines, ideal for small pick-and-place modules and packaging machines. Feature → Business Impact → Application: Buffer cushioning minimizes impact during actuation, lowering wear on seals and guides, extending service life in high-cycle environments, and reducing maintenance costs in repetitive clamping and eject/return cycles. Feature → Business Impact → Application: The magnetic piston enables reliable position sensing and easy integration with control systems, improving feedback accuracy and simplifying sensor wiring for inline quality checks in automated assembly lines. Feature → Business Impact → Application: Stainless steel barrel and martensitic piston rod enhance corrosion resistance and longevity in damp or washdown environments, supporting longer mean time between failures (MTBF) in food and beverage or chemical processing lines. Feature → Business Impact → Application: Rc1/8 port sizing offers compatibility with standard pneumatic manifolds and compressed air lines, reducing installation time and allowing plug-and-play integration with existing equipment in retrofit projects. Feature → Business Impact → Application: Theoretical force of 131 N at rated pressures ensures reliable actuation across 2–10 bar systems, giving engineers confidence for medium-duty positioning and clamping tasks without oversizing the cylinder. Feature → Business Impact → Application: The Roundline series and magnetic option provide a cohesive product family for designers seeking consistent actuation performance and interchangeability across multiple workstations, simplifying spare parts management and stock control. This combination supports lean maintenance, quicker line changeovers, and improved overall equipment effectiveness (OEE).

FAQs
Install the RT/57320/M/25 by mounting the cylinder to a compatible fixture using standard ISO mounting patterns for a 20 mm bore. Connect the Rc1/8 pneumatic supply line securely, ensuring clean, dry compressed air within 2 to 10 bar. Verify the magnetic piston alignment with your sensor or actuator feedback, and inspect the buffer cushioning for proper travel impact control. In retrofit scenarios, confirm porting location and cylinder orientation match the existing control logic to prevent misactuation and ensure seamless signal integration.
The cylinder provides a theoretical force of 131 N at the rated 2 to 10 bar operating range, with buffer cushioning to minimize impact energy during extension and retraction. The 20 mm bore and 25 mm stroke are optimized for compact actuation, enabling reliable movement in medium-duty applications. For precise performance under your exact supply pressure and temperature, consult the datasheet and run a field test under your operating conditions.
Yes. The barrel is made from stainless steel (austenitic) and the piston rod from martensitic stainless steel, providing corrosion resistance and durability in challenging environments. This construction is advantageous in manufacturing lines with exposure to moisture, lubricants, or washdown processes. While material choices support cleaning and longevity, verify any required IP rating or washdown specifications for your plant's standard.
Regularly inspect the buffer cushioning and seals for signs of wear and replace as needed to maintain smooth operation. Use clean, dry compressed air and avoid moisture or particulates entering the line. Check for optimal magnet sensing alignment and verify electrical connections if using position feedback. Periodic lubrication is typically unnecessary for magnetic pistons, but follow your plant's maintenance schedule and the datasheet recommendations to minimize downtime.
