SMC NCDRA1BS50-180 Rack And Pinion Rotary Actuator

SMC NCDRA1BS50-180 is a rack-and-pinion rotary actuator from SMC designed for compact, high-torque rotation in automation. It uses a single-rod configuration and a 50 mm bore (about 2 in), delivering a full 180° rotation for orientation and indexing tasks in tight spaces. Designed for standard pneumatic systems, it is rated for up to 145 psi, enabling reliable operation on typical factory air lines. As part of SMC’s rack-and-pinion rotary actuators, the NCDRA1BS50-180 emphasizes high torque relative to size and precise positioning, making it well suited for part orientation, indexing stations, or rotary transfer in assembly and packaging lines where footprint matters.
