GAC ACB2001 — 2001 Series Universal Rotary Actuator | 24VDC | 12 ft-lb | New
You are purchasing one (1) brand-new GAC ACB2001 Universal Rotary Actuator, 24VDC, the largest and most capable actuator in the GAC lineup. This is a genuine GAC product — not an aftermarket or Chinese clone. Supplied by South Bay Diesel & Hydraulics, Inc., a long-established marine equipment distributor serving commercial fishing fleets, shipyards, and vessel operators worldwide since 1987.
About the GAC ACB2001:
The ACB2001 is GAC's largest and most powerful universal rotary actuator — engineered specifically for mechanical actuation of fuel system control levers on large diesel engines requiring high torque in the 12 ft-lb (16.3 N·m) range. It is a rotary output, linear torque proportional electric servo that delivers fast, precise, and repeatable fuel rack positioning across a wide range of commercial engine applications.
Energized by GAC's ESD5300 Series electronic speed control units, the ACB2001 is capable of 35 degrees of shaft rotation and responds to transient load conditions in under 80 milliseconds — critical for maintaining stable engine speed under variable load. Its internal return spring provides true fail-safe operation: when de-energized, the actuator immediately drives to the fuel shut-off position, preventing runaway.
Real-world application example: The ACB2001 has been deployed on twin Caterpillar 3516 main propulsion engines on commercial tugboats, paired with ESD5330 speed controllers and custom harnesses to synchronize twin engine output to a single drive train — a demanding, high-torque application that demonstrates the unit's capability in serious commercial marine service.
