Norgren KM/8025/M/25 Cylinder - ISO 6432
Part Number: KM/8025/M/25
Quick Summary
KM/8025/M/25 is a stainless steel double-acting cylinder designed for precise linear actuation in food-processing automation. In hygienic lines, corrosion resistance and ease of CIP cleaning address maintenance bottlenecks and contamination concerns. It conforms to ISO 6432, features a magnetic piston for straightforward position sensing, and is purpose-built for demanding environments in the food industry. The robust 25 mm bore and 25 mm stroke deliver repeatable motion across cycles, while buffer cushioning minimizes impact and wear. With standard mounting options and compatible fittings, it supports scalable installations, reduces downtime, and lowers total cost of ownership for OEMs and maintenance teams alike.

Stainless steel body provides excellent corrosion and acid resistance, extending service life in aggressive wash environments and reducing maintenance costs over time. This translates to lower downtime on high-speed production lines and greater process availability in food and beverage applications. The magnetic piston enables reliable, non-contact position sensing with compatible switches, simplifying automation integration and allowing safer, quicker line control. The ISO 6432 conformity ensures you can source compatible mounts, brackets, and accessories from multiple suppliers, accelerating installation and interchangeability across lines. Buffer cushioning delivers controlled deceleration and smoother cycling, reducing wear on end-of-stroke components and improving cycle life in repeat-motion tasks. A 1–10 bar operating range and G1/8 port size offer flexible integration with common pneumatic systems, while the 25/25 mm bore/stroke pair suits compact, high-precision actuations in packaging and hygienic equipment. Fittings such as Pneufit 10 simplify assembly, and mounting options (piston rod clevis, rear hinge, and foot styles) enable quick, vibration-resistant installations. The 304-grade barrel and 303-grade piston rod resist CIP cleaners and sanitize-induced stress, supporting compliant hygienic design. Overall, the KM/8025/M/25 delivers predictable performance, easy maintenance, and robust reliability in demanding industrial environments.

FAQs
KM/8025/M/25 supports standard mounting configurations including Piston Rod Clevis Mounting (KQM/55433/25), Rear Hinge Mounting (KQM/8020/24), and Foot mounting style C (M/P72404). These options enable secure, vibration-resistant installation on compact machinery and conveyors, while maintaining precise stroke alignment and easy service access for maintenance.
Yes. The cylinder uses a stainless steel barrel (AISI 304) and a corrosion-resistant construction designed for aggressive cleaning regimes. Its design minimizes crevice formation and facilitates efficient CIP cycles, helping to maintain hygiene standards and reduce contamination risk in beverage, dairy, and packaged food equipment.
The unit uses a G1/8 port size. Recommended connections include Pneufit 10 push-in fittings such as 102250618 (straight adaptor) and 102470618 (swivel elbow adaptor), plus 10K510618 for banjo flow control. These fittings support fast, reliable assembly and easy field adjustments without special tooling.
The cylinder includes a magnetic piston as standard for straightforward sensing. For external switching, use switch mounting brackets (QM/33/025/22) and reed-switch options like M/50/LSU/5V with a 5 m cable. This combination enables simple, robust position feedback integrated into pneumatic automation chains.
You get a theoretical force of 294 N at the 25 mm bore with a 25 mm stroke. Operating pressure ranges from 1 to 10 bar, and the temperature span is -10 to 80 °C. In production, the combination of copper-free stainless steel components and buffer cushioning supports consistent cycle life and reliable stroke performance in demanding environments.
