SMC CRB2BW20-90SZ Vane Type Rotary Actuator
The SMC CRB2BW20-90SZ is a compact, high-performance pneumatic rotary actuator belonging to the upgraded CRB2-Z series. Utilizing an efficient single vane operation design, this actuator is engineered to turn small, precise loads within highly confined automation spaces.
The CRB2BW20-90SZ features a double-ended shaft configuaration alongside parallel mounted, side-oriented piping ports. This layout greatly optimizes air routing and installation flexibility. Delivering a stable internal rubber bumper cushion to reduce kinetic shock, this double-acting rotary component provides exceptional reliability and rapid cycle execution under a maximum operating pressure of 0.7 MPa.
