Swing Drive Gear Set is the group of gears that connects our swing motor to the turntable so the upper part of the machine spins. We slide these gears onto the motor shaft and mesh them inside the swing gearbox. As the motor turns, the gears transfer power, making sure rotation is smooth and strong. Made of hardened steel, they resist wear when pushing heavy loads. We keep them greased and check for chips or cracks. Good gears mean no jerks when we turn, just steady motion.
