FAQs
KM/8021/M/120 is designed to ISO 6432 standard sizing and uses a G1/8 port, which ensures broad compatibility with existing pneumatic manifolds and mounting hardware. This simplifies integration on new lines and minimizes the need for adapters, reducing installation time and cost in industrial automation projects.
The cylinder utilizes a stainless steel barrel and piston rod (1.4301/304 and 1.4305/303 equivalents) with high corrosion resistance, ideal for washdown and hygiene-sensitive environments. Magnetic piston enables position sensing for automated control, while adjustable cushioning protects sensitive equipment and supports clean-in-place routines.
It has a 20 mm cylinder diameter, 120 mm stroke, double-acting operation, and a theoretical force of 188 N. Operating temperature ranges from -10 to 80 °C and operating pressure from 1 to 10 bar. These specs support reliable actuation across typical food-processing line temperatures and pressures.
Adjustable cushioning allows you to tune impact energy for reduced end-of-stroke wear and quieter operation, extending life and lowering maintenance. The magnetic piston provides feedback for position sensing, enabling closed-loop control and improved repeatability in high-speed packaging and material-handling applications.
Nose mounting nut and piston rod locknut are included, simplifying alignment and secure mounting. The stainless steel construction improves washdown durability, while ISO 6432 compatibility reduces the need for bespoke brackets. Overall, you gain faster commissioning, lower spare-part needs, and predictable lifecycle performance.
