The tension roller is a component of the timing belt assembly. Structurally, the roller is located on a movable axis and serves to maintain the belt in constant tension. This condition is necessary to ensure satisfactory operation of the power unit. It is no secret that the belt drive is quite tangible to the degree of tension. If the degree of tension exceeds the norm, then the timing devices water pump, bearings of the crankshaft and camshaft and generator will be affected by great efforts, and they will wear out to a greater extent.

Also, it is impossible to exclude the wear of the teeth of the belt itself, which significantly reduces its working life. With a slight tension, the belt will slip, which will lead to a malfunction of the valve timing. Therefore, in order to ensure a normally-stable belt tension, the timing drive is equipped with such a device as a tension roller. The roller itself is a metal or plastic pulley with a smooth working edge. Structurally, it is located on radial bearings and bolted. The idler roller bolt is the mounting component of this fixture.
