With a 20 mm bore and 45 mm stroke, the KM/8021/M/45 delivers a compact, ISO 6432–compliant cylinder suitable for tight installations. This size enables reliable linear actuation in confined spaces often found on packaging lines and automated clamps, reducing footprint while maintaining stroke performance. The magnetic piston is standard, enabling straightforward position sensing for PLC or sensor integration without additional components, improving feedback reliability and reducing wiring complexity. Constructed from X5 Cr Ni 18 10 (1.4301: AISI 304) barrel material and X10 Cr Ni S 18 9 (1.4305: AISI 303) piston rod, the unit offers high corrosion resistance—ideal for food processing, chemical handling, and washdown environments. Adjustable cushioning provides controlled deceleration, extending service life and minimizing noise and vibration in high-cycle applications. The operating range of -10 to 80 °C and 1 to 10 bar supports diverse lines, from gentle clamping to more demanding actuation, while G1/8 porting ensures compatibility with standard pneumatic fittings. Nose mounting nut and piston rod locknut are included as standard, accelerating installation and ensuring robust, vibration-resistant mounting in machinery assemblies.

FAQs
KM/8021/M/45 is designed to conform to ISO 6432 with standard mounting interfaces and a G1/8 port. It includes a nose mounting nut and piston rod locknut for quick, secure integration into compact automation layouts, reducing assembly time and ensuring reliable alignment in tight spaces.
Key performance specs include a 20 mm cylinder bore, 45 mm stroke, and a usable operating pressure range of 1 to 10 bar (15 to 145 psi). It operates from -10 to 80 °C and uses a magnetic piston for sensing, making it suitable for hygienic and food-processing environments where reliability matters.
Yes. The KM/8021/M/45 uses stainless steel materials (barrel: 1.4301; piston rod: 1.4305) offering high corrosion resistance, a critical requirement for food-contact environments. Its magnetic piston and adjustable cushioning support cleanability, reduced contamination risk, and durable performance in wash-down cycles.
The cylinder conforms to ISO 6432, which standardizes mounting and size for compact pneumatically actuated cylinders. This compatibility simplifies part replacement and integration across machines built to ISO norms, improving compliance and interchangeability in automated lines.
Routinely inspect the magnetic piston alignment and cushioning settings to preserve smooth operation. The adjustable cushioning allows tuning for cycle life and noise; regular checks of mounting fasteners and port connections ensure continued reliability in high-cycle environments typical of packaging and processing lines.
