Stainless steel construction delivers high corrosion and acid resistance, reducing maintenance frequency and extending service life in washdown environments and food processing lines. This directly lowers downtime costs and increases line availability for packaging, filling, and conveying tasks. ISO 6432 conformity guarantees standardized mounting and compatible replacements across existing equipment, simplifying spares inventory and retrofit projects while enabling faster line upgrades. The magnetic piston is standard, enabling straightforward integration with non-contact sensors for position feedback, which supports reliable automation without additional sensing hardware. Adjustable cushioning provides controlled impact and reduced wear on end-of-stroke hardware, lowering noise and enhancing lifecycle performance in high-cycle applications. A compact 20 mm bore with an 80 mm stroke fits tight machine footprints, and the G1/8 port aligns with common pneumatic fittings, streamlining installation. Nose mounting nut and piston rod locknut are included for secure mounting, improving installation consistency and reducing setup time. The operating pressure range of 1–10 bar and ambient temperature capability from -10 to 80 °C broaden application suitability, delivering consistent actuation across diverse production environments. Overall, the KM/8021/M/R/80 combines durability, standardization, and ease of maintenance to minimize downtime and optimize total cost of ownership in food-grade automation cells.
