This 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, power steering 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 bearing 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

Sealed groove bearing is usually used and it also has built-in heat-resistant grease, a seal, and 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.

Product Function

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
