Norgren KM/8021/M/90 Pneumatic Cylinder - ISO 6432
Part Number: KM/8021/M/90
Quick Summary
KM/8021/M/90 is a stainless steel pneumatic cylinder delivering reliable linear actuation for automation lines and packaging equipment. In harsh production environments, corrosion and unpredictable wear can cause unplanned downtime; this cylinder counters those challenges with a 304-grade barrel and magnetic piston for consistent motion. It is built around ISO 6432 standards and is suitable for food industry applications where hygiene and washdown compatibility matter. With adjustable cushioning and a standard G1/8 port, it offers smooth, controllable action and easy mounting in existing ISO 6432 frames, reducing spare-parts complexity. The combination of robust materials, standard form factor, and clear installation guidelines supports faster procurement cycles and longer service intervals for high-demand systems.

FAQs
KM/8021/M/90 is a double-acting cylinder designed to fit ISO 6432 frames with a G1/8 port size. It includes a nose mounting nut and piston rod locknut for secure, straightforward installation in compact spaces. Compatible with standard ISO 6432 mounting patterns, it streamlines retrofits and new builds alike, reducing the need for custom brackets or adapters.
The cylinder operates at 1 to 10 bar (15 to 145 psi) and handles temperatures from -10 to 80 °C. It provides a theoretical force of 188 N at its 20 mm bore, with an adjustable cushioning option to tailor impact and wear. The magnetic piston enables reliable position sensing for precise control in automated cycles.
Yes. The 20 mm x 90 mm stainless steel cylinder is designed for high-corrosion resistance and washdown-friendly operation, making it well-suited for food handling and clean-in-place environments. The 304 stainless barrel and hygienic construction support sanitation requirements while maintaining robust actuation for demanding lines.
KM/8021/M/90 conforms to ISO 6432, ensuring broad compatibility with standard mounting frameworks and spares. Its stainless steel construction aligns with hygiene-focused applications common in food and beverage equipment. This standardization simplifies procurement and maintenance, reducing downtime and inventory complexity.
The combination of corrosion-resistant materials, a magnetic piston for reliable sensing, and adjustable cushioning reduces wear and maintenance frequency. Standardized ISO 6432 mounting simplifies upgrades and spare-parts sourcing, while secure mounting features decrease installation time and the risk of misalignment, contributing to lower downtime and higher overall equipment effectiveness (OEE).
