The 40 mm bore with a 320 mm stroke in the Roundline family enables a compact footprint while delivering dependable actuation for small-form automation cells. Business impact: space savings that translate to more compact machine layouts and faster line speeds. Application: ideal for tight packaging lines, pick-and-place modules, and clamping stations where stroke length matters. The magnetic piston supports versatile control strategies, including reed-switch sensing, allowing easier integration with existing automation hardware and PLCs. Business impact: improved visibility and fault detection with less wiring complexity. Application: turnkey sensing in constrained layouts. The stainless steel barrel and piston rod provide superior corrosion resistance and long life, reducing maintenance intervals and total cost of ownership in harsh environments. The buffer cushioning reduces impact, extending component life and smoothing cycles for high-speed applications. Business impact: lower downtime and safer operation in high-cycle environments. Application: linear actuation in conveyors, robotic arms, and assembly lines. The Rc1/8 port size and operating range of 1–10 bar facilitate fast, reliable connection to standard shop air, while the -10 to 80 °C operating window supports diverse plant conditions. Theoretical force of 754 N offers robust pushing and pulling capabilities for medium-duty tasks. Application: material handling and fixture operation. Additional benefits come from ready compatibility with Pneufit C fittings, various mounting styles (Nose nut, Nut style, Piston Rod swivels, and universal mounts), and optional magnetic switches for integrated control. Business impact: streamlined installation, easier maintenance, and fewer part numbers to manage in spares inventory. As a result, engineers gain a dependable, durable actuator that aligns with lean manufacturing goals and controlled lifecycle costs.
