A concentric gearbox is a type of mechanical gearbox where the input and output shafts are aligned along the same axis. This design offers a compact and efficient solution for transmitting power in a straight line, making it ideal for space-constrained applications. Concentric gearboxes are commonly used in industries such as robotics, automation, and material handling, where precise motion control and high torque are required. Their simple yet robust design ensures reliability, smooth operation, and minimal maintenance.
