Festo DSR-25-180-P-11911 Pneumatic Rotary Drive

The Festo DSR-25-180-P (11911) is a compact, double-acting pneumatic rotary drive from the DSR series that provides 0° to 180° of adjustable rotation for precise angular positioning in automated machinery. Employing a rotary vane design, it delivers a theoretical torque of about 5 Nm at 6 bar, operates at 1.5 to 8 bar, and features an M5 pneumatic connection, through-hole mounting, elastic cushioning at both ends, a nickel-plated steel shaft, and NBR seals for reliable performance across -10°C to +60°C. Typical applications include manufacturing lines, robotic handling systems, and packaging equipment where controlled rotary motion, indexing, and valve actuation are required, with a swivel frequency up to 3 Hz and ISO 8573-1 compliant compressed air usage.
