FAQs
KM/8021/M/300 uses a standard nose mounting nut and piston rod locknut and is designed for compatibility with ISO 6432 brackets and Norgren mounting accessories. Its 20 mm bore and 300 mm stroke fit compact assemblies, while the mounting options minimize installation time and reduce the need for custom brackets.
Yes. The stainless steel construction with AISI 304 barrel and AISI 303 piston rod provides high corrosion resistance and acid resistance, ideal for food and beverage lines. The magnetic piston supports reliable sensing, and adjustable cushioning helps withstand frequent washdowns without compromising performance.
The unit operates from 1 to 10 bar (15 to 145 psi) with a G1/8 port and a temperature range of -10 to 80 °C (14 to 176 °F). It conforms to ISO 6432 and features a 20 mm bore and 300 mm stroke for consistent motion in compact spaces.
With a theoretical force of 188 N, this double-acting cylinder delivers reliable actuation across standard compressed-air supplies. The 20x300 mm bore/stroke enables precise motion control for pick-and-place and indexing tasks, while adjustable cushioning minimizes impact and extends component life in high-cycle applications.
Adjustable cushioning tailors deceleration to payloads, reducing mechanical shock, seal wear, and rod guide stress. This leads to longer maintenance intervals, higher uptime, and lower total cost of ownership. When combined with a magnetic piston for feedback, you gain predictable performance and easier troubleshooting across production lines.
