FAQs
KM/8025/M/40 supports standard 25 mm bore mounting with available options such as nose mounting nut and piston rod locknut, plus rear hinge, clevis, or foot mounting styles. For fast retrofits, pair with KQM/ mounting accessories and M/50 reed switch where position sensing is required. Ensure porting (G1/8) aligns with your supply fittings.
The cylinder operates between 1 and 10 bar (15–145 psi) and tolerates temperatures from -10 to 80 °C (-14 to 176 °F). This wide range supports washdown environments and varying process temperatures, while the buffer cushioning minimizes impact during high-speed cycles, protecting both equipment and payloads.
Yes. The 25 mm bore stainless steel cylinder is designed for food industry applications, featuring high corrosion resistance and a magnetic piston for safe, reliable sensing. Its ISO 6432 form factor and cleanable surfaces suit CIP/SIP environments, helping maintain hygiene standards and reducing risk of contamination across automated lines.
KM/8025/M/40 conforms to ISO 6432 for interchangeable mounting and fittings, with materials chosen for food-grade environments (stainless steel barrel and piston rod). Its construction supports compliance with hygienic processing requirements, while the magnetic piston enables robust sensing within standard electrical and control architectures.
Anticipate longer service life due to corrosion-resistant stainless steel and acid resistance, reducing replacement costs. Buffer cushioning lowers mechanical wear, lowering maintenance intervals. Magnetic sensing reduces wiring complexity, improving diagnostics. Overall, customers typically see lower downtime and improved uptime reliability in high-cycle automation.
