Norgren KM/8021/M/160 ISO Roundline Cylinder - ISO 6432
Part Number: KM/8021/M/160
Quick Summary
KM/8021/M/160 is a stainless steel ISO roundline double-acting cylinder designed for food-grade automation in packaging and processing lines. In demanding production environments, corrosion and washdown exposure threaten uptime; this unit mitigates those risks with a robust 1.4301 barrel and a magnetic piston for reliable sensing. It conforms to ISO 6432 mounting standards and is suitable for food-industry applications, with adjustable cushioning to tailor speed and impact without external accessories. For buyers prioritizing reliability and lifecycle cost, the combination of high corrosion resistance and predictable maintenance translates to lower downtime and longer service intervals across OEM lines.

Feature → Business Impact → Application: The KM/8021/M/160 uses a 20 mm diameter cylinder with a 160 mm stroke, delivering a compact footprint while maintaining a generous stroke for space-limited automation cells. This enables precise, repeatable actuation in tight packaging or dosing stations, reducing cycle times and increasing line throughput in small-footprint configurations. Feature → Business Impact → Application: ISO 6432 standard mounting and G1/8 port sizing simplify integration with common pneumatic manifolds and mounting brackets, cutting assembly time and-compatible accessory costs for OEMs and service teams. Feature → Business Impact → Application: Double-acting operation with adjustable cushioning lets engineers dial return impact and cushioning efficiency, reducing stray motions and wear in high-cycle applications such as robotic grippers or pick-and-place modules. Feature → Business Impact → Application: A magnetic piston provides reliable position feedback without extra sensors, improving control accuracy during multi-axis sequences and enabling straightforward PLC integration in process lines. Feature → Business Impact → Application: Stainless steel barrel (1.4301) and piston rod (1.4305) deliver excellent corrosion and acid resistance, extending service life in washdown-heavy environments like food processing and beverage filling lines, lowering maintenance costs. Feature → Business Impact → Application: Nose mounting nut and piston rod locknut as standard streamline assembly, reduce field time for installation and rework, and improve vibration resistance in vibrating conveyors and dosing stations.

FAQs
KM/8021/M/160 adheres to ISO 6432 mounting standards and ships with a nose mounting nut and piston rod locknut to simplify attachment. When installing, ensure compatibility with standard manifolds and consider using adjustable cushioning to tune the stroke for your application. Verify clearances and alignment to minimize side loads and maximize seal life.
The cylinder operates from -10 to 80 °C (14 to 176 °F) and handles 1 to 10 bar (15 to 145 psi). These ranges support mixed climate environments and typical factory air systems, offering predictable performance in packaging, handling, and automated assembly lines.
Yes. The 1.4301 stainless steel barrel and 1.4305 piston rod deliver high corrosion resistance ideal for washdown and sanitizable environments. The magnetic piston aids in reliable position sensing, and the ISO 6432 compatibility simplifies integration with food-safe automation systems.
Key differentiators include stainless steel construction for corrosion resistance, a magnetic piston for easy sensing, adjustable cushioning for customizable motion, and ISO 6432 mounting with a compact 20 mm diameter and 160 mm stroke. These features deliver longer life in harsh environments and easier installation in tight spaces.
