The 25 mm cylinder diameter paired with a 250 mm stroke provides robust actuation with a theoretical force of 294 N, delivering consistent motion for small- to mid-sized components in automated lines. This feature translates to higher repeatability and reduced cycle times, particularly in pick-and-place and clamping applications. The Roundline platform is engineered to save up to 20% of space compared with the basic ISO/VDMA length, enabling denser line layouts and simpler cabinet design—fueling efficiency gains and lower installation costs. Magnetic pistons support easy sensing and integration with standard control architectures, improving system diagnostics and reducing wiring complexity. Stainless steel barrels and pistons resist corrosion in demanding environments, extending lifecycle and lowering replacement frequency. Buffer cushioning ensures smooth acceleration and deceleration, minimizing vibration and wear at high-frequency cycles. The Rc1/8 porting aligns with common pneumatic manifolds, simplifying retrofits and upgrades.
