FAQs
KM/8025/MF/250 uses the ISO 6432 standard for mounting, enabling straightforward replacement and integration with compatible end-plates and brackets. Use the nose mounting nut and piston rod locknut provided as standard to secure alignment and minimize eccentric load. Ensure porting aligns with the G1/8 connections and verify proper seal seating to avoid air leaks.
The cylinder operates from 1 to 10 bar (15 to 145 psi). Its theoretical force is 294 N at rated conditions, which supports typical mid-range actuation tasks in packaging and automation. Ensure your downstream valves and controls accommodate this force profile for consistent travel and grip strength.
Yes. The 25 mm diameter stainless steel barrel (X5CrNi18-10 / 1.4301) and corrosion-resistant Piston Rod material (X10CrNiS18-9 / 1.4305) provide excellent resistance to acids and washdown. Magnetic piston aids sensing in hygienic environments, and buffer cushioning helps maintain performance under frequent washing cycles typical in food processing.
To maximize life, perform regular visual inspections for seal wear and mounting integrity, confirm cushion settings are intact, and monitor the magnetic piston feedback for sensor drift. Use clean, dry compressed air and avoid contaminant ingress. Routine cycling tests during commissioning help verify performance and prevent unexpected downtime on critical lines.
Absolutely. The magnetic piston is designed to provide reliable positional feedback, enabling straightforward integration with PLCs, sensors, and control modules. This enables closed-loop control, precise stop positions, and improved repeatability on end-of-line operations and pick-and-place tasks.
