Norgren KM/8025/MU/25/37 ISO roundline cylinder - ISO 6432
Part Number: KM/8025/MU/25/37
Quick Summary
KM/8025/MU/25/37 ISO roundline cylinder delivers reliable double-acting linear actuation for hygienic manufacturing lines. In practice, engineers contend with corrosion, contamination, and downtime; this unit addresses those by combining a stainless-steel barrel and seals designed for CIP environments. Key standards and features include ISO 6432 mounting compatibility, high corrosion resistance, and a magnetic piston as standard for straightforward position sensing in automation loops. The design supports food-industry applications with its robust materials and compatibility with compressed air at typical plant pressures. Coupled with compact sizing and standard cushioning, this cylinder helps reduce maintenance cycles and operating costs while improving pick-and-place accuracy in high-turnover lines.

Stainless steel construction delivers superior corrosion resistance in CIP environments, extending service life and lowering total cost of ownership. Fewer unplanned outages translate to higher line uptime and lower maintenance spend, which is critical in dairy, meat processing, and beverage packaging where sanitization is routine. Magnetic piston is standard, enabling straightforward position sensing without extra hardware. This reduces wiring and simplifies integration, improving control loop responsiveness on automation lines in high-speed packaging and filling. Buffer cushioning minimizes impact and reduces noise, protecting seals during high-cycle operation; this yields smoother starts and repeatable motion at varying pressures in pick-and-place and conveyor duties. ISO 6432 mounting compatibility and G1/8 port simplify retrofit and installation; the compact 25 mm bore fits tight spaces on inline lines and where space is constrained. Material choices—barrel 1.4301 (AISI 304) and piston rod 1.4305 (AISI 303)—deliver robust wear resistance and cleanability. Theoretical force of 294 N at standard pressures enables reliable actuation across typical factory conditions, while a operating range of -10 to 80 C and 1 to 10 bar broadens application scope and reduces the need for multiple part variants.

FAQs
Follow ISO 6432 mounting guidance and use the nose mounting nut plus piston rod locknut supplied. Connect the G1/8 port to a clean, dry compressed air supply within 1–10 bar. Ensure the stroke length (25 mm) matches the cycle, verify there is no obstruction, and assemble any compatible sensors if you plan to use the magnetic piston for position feedback.
The cylinder operates from 1 to 10 bar (15 to 145 psi) and withstands temperatures from -10 to 80 °C (-14 to 176 °F). Use clean, dry air to avoid deposits, and avoid rapid pressure changes that could impact cushioning or wear.
Yes. The 25 mm bore cylinder features a stainless-steel barrel and corrosion-resistant piston rod, designed for hygienic environments. It conforms to ISO 6432 standards and includes a magnetic piston for sensor-friendly integration in automated food-processing lines.
Yes. The cylinder ships with a magnetic piston as standard, enabling non-contact position sensing. This simplifies wiring and enhances feedback reliability for PLCs and sensors used on packaging, filling, and conveying lines.
Plan routine inspections based on cycle rate and environment. Check seals and cushioning for wear after CIP cycles and high-duty tasks. Keep the air supply clean and dry to minimize deposits. Replace worn seals or cushions per manufacturer guidelines to maintain stroke accuracy and repeatability.
