Koganei RANS50-90 Pneumatic Rotary Vane Actuator 90 Degree Bore 50mm Japan

Koganei RANS50-90 Pneumatic Rotary Vane Actuator 90 Degree Bore 50mm Japan

The Koganei RANS50-90 is a compact pneumatic rotary vane actuator with a 90-degree rotation angle and 50mm bore. Vane-type rotary actuators use compressed air acting on an internal vane to produce limited-angle rotational output, converting pneumatic pressure directly into torque without the need for a rack-and-pinion or scotch yoke mechanism. The RANS50-90 features double-ended output shafts, allowing attachment to a driven load from either side, and two top-mounted needle-valve flow controllers for independent speed adjustment of each rotation direction.

Applications

Pneumatic rotary vane actuators like the Koganei RANS50-90 are standard components in factory automation and industrial machinery. They are commonly used to drive pick-and-place arms, indexing fixtures, clamping mechanisms, diverter gates, and workpiece positioning systems where a precise, repeatable limited-angle rotation is needed. The compact vane design makes them well-suited for applications where space is constrained and moderate torque at a fixed stroke angle is sufficient. Koganei is a Japanese pneumatics manufacturer whose actuators are widely used in semiconductor handling equipment, assembly automation, and general industrial machinery. The RANS series in particular is suited to applications requiring repeatable 90-degree positioning, such as part transfer and orientation tasks on automated production lines.
