IMI Norgren KM/8021/M/225 Cylinder - ISO 6432
Part Number: KM/8021/M/225
Quick Summary
KM/8021/M/225 cylinder is a stainless steel double-acting actuator delivering precise linear motion in automated lines. Corrosion, inadequate cushioning, and tough washdown routines often drive maintenance costs and unplanned downtime. The unit adheres to ISO 6432 and features a magnetic piston for reliable sensing, plus high corrosion resistance suitable for food environments. This combination translates to improved uptime, lower total cost of ownership, and smoother integration with existing pneumatic networks. Engineers appreciate a robust solution that supports clean-in-place environments and standard mounting. The design reduces variability in stroke and force delivery, enabling more predictable cycle times and safer, more efficient operation on harsh production floors.

Stainless steel construction delivers high corrosion resistance, extending service life in washdown and food-contact environments. This reduces replacement costs and unplanned downtime, especially in lines with frequent sanitization and temperature cycling. Use on meat, dairy, and beverage processing equipment where hygiene and durability are critical. ISO 6432 compatibility and a 20 mm bore with a 225 mm stroke ensure straightforward interchangeability with existing fixtures, simplifying retrofits and standardizing mounting across cells. The magnetic piston enables reliable position sensing, facilitating seamless integration with factory automation and control loops. Adjustable cushioning provides controlled deceleration, reducing mechanical stress and extending component life in high-speed cycles. A G1/8 port, 1–10 bar operating range, and broad temperature tolerance support flexible plumbing and site-wide deployment. Nose mounting nut and piston rod locknut standardize assembly and maintenance, lowering installation time and part variance across shifts. This combination supports lower total cost of ownership, faster commissioning, and predictable performance in demanding environments. In practice, these features translate to improved uptime, consistent cycle times, and safer operation on harsh production floors.

FAQs
This cylinder uses a G1/8 port and adheres to ISO 6432 mounting standards, with nose mounting nut and piston rod locknut included for quick, secure installation. For retrofit work, verify existing mounting holes and cylinder alignment to ensure smooth integration with your modules and sensors. Ensure the clevis or rod end matches your chosen actuator linkages and that pneumatic lines are sized to maintain proper flow at the 1–10 bar operating range.
Operating pressure is 1 to 10 bar (15 to 145 psi), and operating temperature ranges from -10 to 80 °C (-14 to 176 °F). These specs support reliable performance in common automation environments, including refrigerated, ambient, and heated lines, while maintaining consistent force delivery and stroke integrity.
Yes. The cylinder features stainless steel construction with high corrosion resistance and is designed for demanding washdown conditions typical of the food industry. Its magnetic piston aids sensing in automated lines, and the adjustable cushioning helps maintain equipment longevity by minimizing impact forces during cycling.
The data shows ISO 6432 conformance as a standard for this model, with features optimized for food-grade environments. There are no explicit SIL, CE, or IP ratings listed in the provided data; for regulatory compliance, consult the datasheet and your regulatory team to confirm suitability for your specific application and region.
Adjustable cushioning dampens end-of-stroke impact, reducing wear on mounting fixtures and extending piston life, which lowers maintenance frequency and part replacement costs. The magnetic piston supports straightforward position sensing for reliable automation feedback, improving cycle predictability and helping optimize uptime and throughput in high-demand lines.
