Rotating type Idler Gears are used to ensure that the rotation of two gears is the same. An idler gear is placed between two gears. These Idler Gears rotate in the opposite direction as the driver gear, and the follower gear rotates in the opposite direction of the idler, the same direction of the driver. These Idler Gears are also used to change the spacing between the input and output axles. Rotating type Idler Gears find application in various industrial sectors.
