Description

The output shaft moves in both directions and can stop at any point in the stroke. The hardened steel crankshaft is driven through a train of precision hobbed gears sealed in oil. This reliable actuator is driven by a shaded pole motor completely submerged in oil and sealed in an aluminum case, minimizing maintenance.
