Feature: ISO 6432 compliant, 20 mm bore, double-acting cylinder with a stainless steel barrel. Business Impact: Standardized form factor reduces integration risk and spares inventory complexity across multi-vendor assemblies. Application: Ideal for compact pick-and-place, packaging, and filling stations where space is limited and hygiene matters. Feature: Magnetic piston as standard and buffer cushioning. Business Impact: Improves reliability and end-of-stroke control while reducing impact forces, lowering wear, and extending service intervals. Application: Food-grade conveyors and washdown-ready lines where precise stop positions are essential. Feature: Materials - Barrel and Piston Rod (304/303 stainless steel equivalents). Business Impact: Superior corrosion resistance and wash-down durability translate to lower maintenance, fewer leaks, and reduced contamination risk. Application: Processing, filling, and bottling lines in hygienic environments. Feature: Port Size G1/8 and 20 mm diameter, 25 mm stroke. Business Impact: Compatible with standard Pneufit 10 fittings and common mountings; simple sizing minimizes redesigns and downtime. Application: Modular automation cells and retrofit projects. Feature: Cushioning options (Buffer cushioning) and mounting versatility (rear hinge, piston rod clevis, foot mounting). Business Impact: DK-rated cushioning reduces gear wear and product impact, while flexible mountings speed up installation. Application: Robotic end-effectors, palletizing, and inline actuators. Feature: Switch and accessory readiness (Magnetically operated reed switch and mounting brackets). Business Impact: Enables quick sensor integration for feedback control and predictive maintenance. Application: Position sensing in automated lines and safety interlocks. Industry Insight: In food-processing environments, ISO 6432 compliance, corrosion resistance, and modular mounting capabilities are decisive for achieving reliable uptime and cost-efficient maintenance programs. Integrating this cylinder with 20 mm bore systems, Pneufit fittings, and compatible switch options supports lean automation and scalable line design.

FAQs
KM/8020/M/25 supports multiple mounting options to fit constrained spaces, including rear hinge mounting (KQM/8020/24), piston rod clevis mounting (KQM/8020/25), and foot mounting (M/P72404). These configurations, combined with 20 mm bore and 25 mm stroke, enable flexible installation on compact automation cells. Mounting parts are designed for quick alignment and minimal fixture changes during retrofit projects.
The 20 mm bore with a 25 mm stroke delivers a balanced actuation profile, achieving up to 188 N of theoretical force at rated pressure. The system benefits from buffer cushioning to reduce impact and wear, enabling smoother cycles and longer service intervals. Under typical plant pressures of 1–10 bar, this combination supports reliable, repeatable motion in packaging and handling tasks.
Yes. The stainless steel barrel and corrosion-resistant piston rod are designed for hygienic operation and frequent washdowns common in food and beverage applications. The device is ISO 6432 compliant, and the magnetic piston aids reliable position sensing in automated lines. Combined with compatible fittings and mounting options, it offers a durable solution that minimizes contamination risk and downtime.
The KM/8020/M/25 conforms to ISO 6432, ensuring dimensional compatibility with common international enclosures and mounting hardware. The magnetic piston and stainless steel construction support reliable operation in challenging environments, while standard porting (G1/8) and widely supported fittings simplify integration into existing control architectures and pneumatic manifolds.
Maintenance benefits come from corrosion-resistant materials, magnetic piston for reliable sensing, and modular mounting options that ease replacement and upgrades. The expected ROI improves with reduced downtime, lower contamination risk, and longer service life due to robust stainless steel components. Leveraging standard fittings and mounts also minimizes spare parts inventory and simplifies procurement across multiple lines.
