Rotac SS-001-1V Rotary Hydraulic Actuator Unit

Rotac SS-001-1V is a hydraulic rotary actuator from Micromatic’s Rotac HYD-RO-AC SS Series, engineered to deliver robust rotary motion under hydraulic pressure. It is rated up to 3,000 psi and provides a rotation range of about 280° (±5°), suitable for applications requiring a sizable sweep in confined spaces. The unit uses a solid shaft with a 1.036-inch diameter and a 1.07-inch extension; the shaft features a 0.750-inch-long keyway that is 0.250 inch wide and 0.905 inch deep, enabling secure coupling to driven components. Hydraulic ports are 1/8-27 NPT, aligning with the SS-series standard porting. Data catalogs and distributor listings confirm the SS-001-1V designation within the HYD-RO-AC family and the solid-shaft construction. This actuator is intended for high-pressure hydraulic rotary actuation in industrial automation contexts where a robust, compact rotary drive is required.
