High corrosion resistance and acid compatibility are built into the KM/8021/M/260 stainless steel cylinder, delivering extended service life in washdown environments. This translates to lower maintenance costs and fewer unexpected failures in continuous production lines. Ideal for food processing, pharma, and chemical handling, the unit meets ISO 6432 standard, ensuring straightforward replacement and compatible mounting with common pneumatic manifolds. Magnetic piston is standard, enabling reliable position sensing without extra components. Operators gain better control with sensor-friendly feedback for automated cycles, reducing setup time and improving cycle accuracy. In practice, this supports predictive maintenance and tighter process control across packaging and assembly lines. Double-acting operation with adjustable cushioning reduces impact, wear, and noise during piston transitions. Cushioning can be tuned to match load and speed, delivering smoother operation in high-cycle applications and protecting adjacent machinery. Combined with a 260 mm stroke, this cylinder provides ample travel for reach and reach-and-return tasks in automation layouts. Installation and compatibility are simplified by ISO 6432 mounting conventions and a G1/8 port, along with nose mounting nut and piston rod locknut as standard. This design minimizes custom machining and supports quick swaps in existing lines, lowering downtime during changeovers. The stainless steel construction and standard accessories contribute to a reliable, long-life solution in demanding environments. Materials and build quality matter: barrel in X5CrNi18-10 (AISI 304) and piston rod in X10CrNiS18-9 (AISI 303) resist corrosion and chemical attack, reinforcing product integrity. Theoretical force is 188 N, supporting medium-load actuation without sacrificing compactness. Overall, KM/8021/M/260 combines rugged construction with precise control for durable pneumatic actuation in industrial settings. Robust seals and precision machining help minimize leak points, ensuring consistent pressure and response in automated lines. This reliability translates to smoother integration with PLCs and third-party controls, enabling more predictable cycle times, easier retrofits, and lower total cost of ownership over the system lifecycle.

FAQs

KM/8021/M/260 uses standard ISO 6432 mounting. Ensure porting aligns with G1/8 fittings, use the nose mounting nut and piston rod locknut provided, and verify adjustable cushioning is set to match load and speed. This minimizes alignment errors and reduces changeover downtime.
The cylinder provides a theoretical 188 N of force with a 20 mm bore and 260 mm stroke. Operating pressure ranges from 1 to 10 bar, enabling reliable actuation for mid-load applications while preserving compactness.
Yes. The barrel is constructed from X5CrNi18-10 (AISI 304) stainless steel and the piston rod from X10CrNiS18-9 (AISI 303), delivering high corrosion resistance suitable for washdown and food-processing environments.
The KM/8021/M/260 conforms to the ISO 6432 standard for cylindrical pneumatic actuators, and its materials and design support use in hygienic, food-grade environments.
Adjustable cushioning reduces impact and wear, lowering maintenance needs. The magnetic piston enables easier sensing and integration with controls, while corrosion resistance from stainless steel construction reduces downtime and replacement costs over the lifecycle of automated lines.
