Tensioner Idler-1


Introduction of Tensioner & Idler

Tensioner & Idler Bearing is located in the front of an internal combustion engine. It provides tension to the belt which drives from the crankshaft, to the cam shaft, alternator, air compressor, powersteering pump, and water pump. It must handle high temperatures, high-speed rotation, and belt vibration because of contiguity in the engine used in order to make the direction of a belt change. These bearings are designed against different specification from normal deep groove bearings. These bearings are divided roughly into two types and identified by the usage respectively.

1. Tensioner Bearing

Bearing which applies tension to the drive belt, and prevents slack

2. Idler Bearing

Bearing which affects a change in the angle of direction which a belt runs or to adjust contact width with a pulley.

Structure of Tensioner & Idler

Sealed groove bearing is usually used and it also has built-in heat-resistant grease, a seal, and the retainer and the structure can withstand a temperature change or change of belt tension when the car is running.

1. Tensioner Bearing

The rotation center is movable in order to give tension to the belt.

2. Idler Bearing

Unitized with the pulley


Tensioner Idler-3

   ◎ Function of Tensioner & Idler

The following are important functions of these indispensable parts for the smooth drive of the belt system.

1. To add initial tension by using the pivot hole and eccentric hole which absorb tension changes in the timing belt where the temperature changes when the engine is running.

2. To prevent any belt-skip, which would cause mis-matching of the valve timing between crank shaft and cam shaft.
