An electro-hydraulic thruster is a self-contained actuator that converts electrical power into linear motion using a small motor-driven pump and hydraulic cylinder. In many industrial braking systems—especially electro-hydraulic drum brakes—the thruster provides the force needed to release (or actuate) the brake against spring pressure. When energized, the thruster extends or retracts to move the brake mechanism; when power is removed, springs return the brake to its default applied state, delivering fail-safe behavior.
Thrusters are valued for reliability, strong output force, and suitability for harsh environments. They simplify installation by requiring only an electrical connection rather than an external hydraulic power unit.
When selecting a thruster, consider stroke, thrust force, duty cycle, ambient temperature, enclosure protection (IP rating), and—where required—explosion-proof certification. Common issues like slow response or insufficient stroke often trace back to incorrect sizing, poor power supply stability, or contaminated internal fluid.
