Norgren KM/8021/M/40 ISO Roundline Cylinder - ISO 6432
Part Number: KM/8021/M/40
Quick Summary
KM/8021/M/40 ISO roundline stainless cylinder provides reliable double-acting pneumatic actuation for automated production lines. In practice, engineers face corrosion, downtime, and inconsistent cushioning, which can drive maintenance costs and tardy cycle times. It conforms to ISO 6432 and is suitable for food processing environments, bringing high corrosion resistance and a magnetic piston for easy feedback. For system integrators, the compact 20 mm bore and 40 mm stroke with a G1/8 port simplify mounting and wiring, delivering repeatable performance and reduced commissioning time alongside robust reliability.

Stainless steel construction delivers high corrosion and acid resistance, extending service life in washdown and harsh environments, which lowers replacement costs and downtime. This directly translates to safer, cleaner equipment in food and beverage lines while maintaining consistent actuation quality. The magnetic piston enables straightforward non-contact position sensing, reducing the need for additional sensors and simplifying integration with existing controls. By conforming to ISO 6432 and offering a 20 mm bore with a G1/8 port, it fits standard manifolds and small- footprint installations, accelerating panel wiring and rack assembly. Adjustable cushioning absorbs impact and minimizes shock loads, protecting guide rails and end caps, and extending life in high-cycle applications. Theoretical force of 188 N supports moderate payloads, while operating range of 1–10 bar and temperature -10 to 80 °C ensure reliable performance across diverse processes. Mounting options KQM/8020 family and foot mounting M/P72404 simplify retrofits and new builds alike, and Pneufit 10 6 mm/ G1/8 fittings reduce installation time and leak risk, boosting overall system efficiency.

FAQs
KM/8021/M/40 supports Pneufit 10 push-in fittings with 6 mm tubing and a G1/8 port. Examples include 102250618 straight adaptor and 102470618 swivel elbow, plus 10K510618 banjo flow control, enabling rapid, leak-free plumbing and flexible routing in confined spaces.
Key specs: 20 mm cylinder diameter, 40 mm stroke, double-acting operation, G1/8 port size, ISO 6432 standard, magnetic piston, adjustable cushioning, operating temperature −10 to 80 °C, operating pressure 1–10 bar, theoretical force 188 N, and stainless steel barrel/piston rod materials.
Yes. The stainless steel construction provides high corrosion and acid resistance, making it well-suited for washdown and hygienic environments typical of food processing, while ISO 6432 compatibility ensures reliable integration with standard equipment and mounting interfaces.
Multiple mountings are supported, including rear hinge mounting (KQM/8020/24), foot mounting (M/P72404), and piston rod clevis mounting (KQM/8020/25). This flexibility simplifies retrofits and new installations, enabling stable positioning on compact assemblies and tight spaces.
The cylinder provides a theoretical force of 188 N with an operating pressure range of 1–10 bar. This configuration supports moderate loads with consistent stroke timing, improving cycle reliability, reducing cycle time variation, and enabling predictable handling of small to medium actuated loads in packaging, assembly, and process lines.
