Industrial SF 100-90N Pneumatic Rotary Actuator

SF100-90N 90° pneumatic rotary actuator (also listed as SF100-90N-C) from Zimmer Group is a compact flat swivel unit that converts compressed air into precise 90-degree rotation for handling tasks. The 90° swivel angle is matched to a rated torque of 20 Nm, with a 15 mm passage bore and a nominal operating pressure of 6 bar (range 3–8 bar). The design supports axial bearing loads up to 2500 N and radial bearing loads up to 155 Nm, with a repetition accuracy of ±0.01°. The variant integrates into pneumatic pressure chambers to provide adjustable end-position damping, helping control overshoot at the end of rotation. Typical applications include mounting grippers, sensors, or other end-effectors in compact handling cells where controlled 90° rotation is required, such as part orientation, transfer between stations, and precise index drives in automation lines.
