Feature: ISO 6432 standard compatibility and G1/8 port size enable seamless integration with existing pneumatic circuits and compact enclosures. Impact: Reduces installation time and inventory needs while allowing quick swaps in standard manifolds. Application: Suitable for compact pick-and-place and linear actuation in narrow spaces. Feature: Magnetic piston as standard provides reliable position feedback without external sensors. Impact: Improves control accuracy and reduces wiring complexity on high-cycle lines. Application: Essential for automated packaging and labelling stations where precise stroke end-detection matters. Feature: 20 mm bore with 200 mm stroke delivers substantial stroke force for small-diameter cylinders. Impact: Maximizes available travel per unit, boosting cycle rate and throughput in confined layouts. Application: Used in sorting, transfer, and alignment tasks in automation lines. Feature: High corrosion and acid resistance due to stainless steel barrel and corrosion-resistant piston rod. Impact: Extends service life in challenging environments such as washdown zones and food-processing areas. Application: Hygienic, sanitary automation requiring cleanability and durability. Feature: Adjustable cushioning and standard nose mounting nut and piston rod locknut simplify setup and installation. Impact: Reduces impact damage, wear, and maintenance downtime while enabling field-configuration tweaks. Application: Ideal for retrofit projects and OEM fixtures where dependable mounting is critical. Feature: Operating range 1–10 bar and -10 to 80 °C extend suitability across diverse plant conditions. Impact: Enables multi-site deployment with consistent performance, lowering spare parts variety. Application: General-purpose pneumatic actuation in conveyors, transferers, and robotic grippers.

FAQs
KM/8021/M/200 uses standard ISO 6432 mounting and a G1/8 port, with a nose mounting nut and piston rod locknut included. This enables straightforward installation into common pneumatic manifolds and OEM fixtures, reducing setup time and ensuring a secure, vibration-resistant fit.
The cylinder is rated for 1 to 10 bar (15 to 145 psi). This broad range supports multiple plant requirements, from high-speed pick-and-place to gentle positioning, while maintaining consistent force and speed characteristics.
Yes. The barrel is made from stainless steel (AISI 304) and the piston rod from AISI 303, delivering high corrosion resistance and acid resistance. These materials, combined with hygienic-ready design, make it well-suited for food-processing applications where cleanliness and durability matter.
The barrel uses X5CrNi18-10 (AISI 304) stainless steel, and the piston rod uses X10CrNiS18-9 (AISI 303). These alloys provide excellent corrosion resistance, good mechanical strength, and robust performance in challenging environments, including washdown and sanitization cycles.
To maximize longevity, ensure clean, dry compressed air, verify the adjustable cushioning is set to the correct impact level for your load, and periodically inspect the mounting hardware for tightness. Use the magnetic piston feedback to verify consistent position sensing and schedule routine checks as part of your preventive maintenance plan.
