Norgren KM/8025/M/450 – Roundline ISO Cylinder (ISO 6432)
Part Number: KM/8025/M/450
Quick Summary
Norgren KM/8025/M/450 is a double-acting stainless steel cylinder designed for precise actuation in automated production lines. Users often struggle with corrosion, wear in washdown areas, and unpredictable cushioning that disrupts cycle times. This cylinder conforms to ISO 6432, features a magnetic piston as standard, and offers buffer cushioning for controlled strokes. Designed for food-industry applications, it supports a 25 mm bore, 450 mm stroke, and an operating range of 1 to 10 bar, enabling reliable uptime. The G1/8 port, rugged stainless body, and standard mounting options simplify installation and reduce total cost of ownership. Its 294 N nominal thrust provides robust actuation at mid-stroke, supporting repeatable performance in modular automation lines.

The KM/8025/M/450 uses a corrosion-resistant stainless steel barrel and a robust piston rod, delivering extended service life in washdown and caustic cleaning environments. This directly reduces maintenance intervals and replacement costs while maintaining sealing integrity in food-processing lines. A magnetic piston is standard, enabling straightforward position sensing and safer integration with sensors and control systems, which translates to simpler wiring and fewer integration issues on busy assembly floors. ISO 6432 compliance ensures dimensional interchangeability, speeding cross-vendor component replacement and helping maintenance teams keep spares aligned with existing inventory. Buffer cushioning delivers smooth starts and stops, minimizing peak loads on seals and mounts to extend downtime between service events. With a 25 mm bore, 450 mm stroke, and G1/8 port, the unit fits a wide range of compact automation modules while preserving mounting flexibility. Nose mounting nut and piston rod locknut are standard, accelerating alignment during installation and reducing commissioning time. The piston and barrel materials (AISI 304/303 equivalents) provide a durable, hygienic profile suited for tough environments, and a broad operating window of -10 to 80 °C and 1 to 10 bar supports consistent performance in food, beverage, and packaging lines. Theoretical thrust of 294 N ensures reliable actuation across mid-stroke ranges, enabling predictable motion profiles in modular lines designed for scalability.
