FAQs
Yes. KM/8021/M/70 is ISO 6432 compliant, and its 20 mm bore and G1/8 port are designed for compatibility with standard ISO mounting plates and feet. This allows fast retrofit and straightforward enclosure integration without special adapters.
The cylinder operates from -10 to 80 °C (14 to 176 °F) and supports an air pressure range of 1 to 10 bar (14.5 to 145 psi). These ranges ensure reliable performance in typical factory environments and fluctuating line conditions.
Yes. The barrel is made from stainless steel (AISI 304) and the piston rod from AISI 303, providing excellent corrosion resistance and cleanability for food-grade equipment and sanitary washdown conditions.
Theoretical force is 188 N. Adjustable cushioning reduces impact forces at end-of-stroke, protecting neighboring components and extending life in high-cycle applications; ideal for packaging and automated handling lines.
Utilize the standard nose mounting nut and piston rod locknut for secure mounting. Pair with compatible Norgren mounting accessories, inspect seals periodically, and use proper lubricants to maintain smooth operation and extend service life in washdown environments.
