Norgren RT/57225/MC/125 Pneumatic Cylinder - Roundline
Part Number: RT/57225/MC/125
Quick Summary
Norgren RT/57225/MC/125 is a compact pneumatic cylinder designed for reliable linear actuation in automation and material handling. Engineers often struggle with space constraints and the need for consistent sealing in tight installations. Typical industry standards for pneumatic cylinders include CE compliance, IP ratings, and SIL safety integration to ensure safe, reliable operation. This model combines a 25 mm bore and 125 mm stroke with stainless steel barrel and magnetic piston, enabling long life and easy switch integration. It also delivers space savings and predictable performance in high-cycle lines, while compatible with standard mounting configurations to reduce integration time and total cost of ownership.

Feature → Business Impact → Application: The RT/57225/MC/125 uses a 25 mm bore and 125 mm stroke to deliver precise, repeatable linear motion with a theoretical 294 N force, supporting smooth starts and controlled stopping thanks to buffer cushioning. This translates to higher assembly accuracy in pick-and-place and clamping tasks on conveyors, reducing cycle times and waste. The space-saving Roundline design trims overall length by about 20% versus a basic ISO length, enabling denser automation cells and simpler cabinet layouts. Stainless steel barrel and martensitic piston rod improve corrosion resistance and durability, extending service life in moderate washdown environments and reducing maintenance intervals. A magnetically actuated piston supports easy integration with switches for position sensing and control, simplifying wiring and reliability. Rc1/8 porting and standard end-caps ensure straightforward installation and compatibility with common manifolds and mounting patterns. Cushioning, robust end caps, and magnetic piston combine to support high-cycle applications with lower downtime and longer life.

FAQs
RT/57225/MC/125 uses standard roundline end-cap construction with compatible mounting patterns and Rc1/8 porting, enabling straightforward installation on existing manifolds and brackets. Its magnetic piston supports easy integration with proximity switches for sensing, while the 125 mm stroke pairs with a compact 25 mm bore to fit tight automation cells without compromising reach. For retrofit projects, ensure mounting holes align with ISO/VDMA guidelines to minimize rework and downtime.
The double-acting construction provides actuation on both extend and retract strokes, delivering consistent force on both directions. This improves cycle timing and positioning accuracy, reduces dwell times, and enables faster return cycles in pick-and-place or transfer operations. The inclusion of buffer cushioning further suppresses impact, extending seal life and reducing vibration-related wear in high-speed applications.
The cylinder features a stainless steel barrel and martensitic piston rod, offering enhanced corrosion resistance and durability over standard carbon steel variants. While this improves longevity in environments with moisture or mild washdown, verify your specific process requirements and ambient contaminants. For demanding washdown or sanitization, pairing with compatible seals and protective housings is recommended to maximize service life.
Routine maintenance focuses on ensuring clean, dry air supply and inspecting seals, end caps, and magnet-enabled sensors. Periodically check for wear on the piston rod and cushioning components, and replace seals as part of a preventive maintenance plan to avoid pressure loss and leakage. With its robust stainless components and low-friction seals, the cylinder offers longer intervals between servicing when kept in proper operating conditions.
You can expect improved space efficiency and higher line density due to the 20% footprint reduction versus basic ISO-length cylinders. The rugged stainless steel construction and magnetic piston contribute to lower maintenance and longer service life, reducing downtime. The cylinder’s compatibility with standard fittings and sensing devices also speeds up installation and changeovers, delivering faster time-to-production and reduced total cost of ownership.
