Norgren KM/8025/M/90 ISO Roundline Cylinder - ISO 6432
Part Number: KM/8025/M/90
Quick Summary
Norgren KM/8025/M/90 is an ISO roundline double-acting cylinder for automated handling in food processing. Engineers face corrosion, contamination, and inconsistent actuation in wash-down environments; this unit’s stainless steel barrel and magnetic piston address those pain points while delivering reliable stroke performance. The cylinder conforms to ISO 6432 and provides robust duty under sanitizing cycles, with buffer cushioning for gentle starts and stops. Designed for ease of installation, it features a nose mounting nut and piston rod locknut as standard. By combining high durability with sanitary design, it supports longer service life, reduced maintenance, and safer, compliant automation in hygienic production lines. Secondary benefits include compact integration with ISO 6432 mounting systems and compatibility with standard compressed air controls, improving overall line uptime.

FAQs
KM/8025/M/90 uses a standard ISO 6432 footprint and G1/8 port, plus a nose mounting nut and piston rod locknut as standard. For retrofit projects, verify existing mounting plates align with ISO 6432 dimensions and confirm the available space for the 25 mm bore and 90 mm stroke. When integrating sensors, the magnetic piston supports reliable proximity switch sensing without additional adapters.
The cylinder has a 25 mm bore and a 90 mm stroke, delivering a theoretical force of about 294 N. This combination supports medium-duty actuations with predictable speeds under 1–10 bar. For higher speeds, ensure adequate compressed air flow and manage cushioning settings to avoid overshoot while maintaining control over the load cycle.
Yes. The stainless steel housing (AISI 304) and protective design provide high corrosion resistance, making it suitable for washdown and sanitary environments. The magnetic piston aids sensing in automated lines, while buffer cushioning reduces splash and mechanical stress, contributing to longer service life in hygienic manufacturing settings.
The unit operates from -10 to 80 °C (14 to 176 °F) and is rated for 1 to 10 bar (15 to 145 psi). These ranges support a wide variety of production environments, enabling consistent performance across temperature swings and pneumatic supply variations commonly found in food, packaging, and general automation.
Regular inspection of the seals and rod area is advised, especially in washdown environments. Because the cylinder uses stainless steel components and a magnetic piston, cleaning should avoid aggressive solvents that could affect seals. Schedule periodic checks of the locknut and mounting hardware, and replace worn seals promptly to maintain performance and prevent leakage.
