SMC NCRA1BS50-90 is a compact rack-and-pinion pneumatic rotary actuator that provides 90° of rotation in a 50 mm body size, designed for precise indexing and position control in automated assemblies. It belongs to SMC’s NCRA1 family, using a rack-and-pinion mechanism to deliver rotary motion from linear actuation, with mounting options that fit tight spaces. Order-code suffixes may indicate options such as air cushions or built-in magnets. Typical applications include packaging lines, assembly stations, and machine-tending tasks where compact rotary motion and repeatable positioning are required.
