Tensioner Sprockets

From the word tension (a force applied to a continuous web of material in a machine), a Tensioner is a device that is used to apply force to an object to retain the tension. It regulates the tightness and movement of a thread in an object. Power Transmission systems use Tensioners to keep V Belts and Roller Chain tight within a drive. The tensioner is made up of two parts: a Tensioner Arm and a Tensioner Sprocket or Tensioner Roller.

A Tensioner Sprocket is a circular steel component, with teeth-shape cuts around the edges. Its function is not to drive or be driven by a chain but to guide and maintain its movement. A vehicle such as a car is a good example of a machine that uses Tensioner Sprockets. The chains inside the vehicle provide an assurance that the driving pulley will be tight enough and will not become loose.
