       It provides tension to the belt which drives from the crankshaft, to the cam

       haft,alternator, air compressor,power steering pump,and water pump.

       It must handle high temperature, high-speed rotation,and belt vibration

       because of contiguity in the engine used in order to make the direction of a


      The following are important funtions of these indispensable parts for the smooth

      drive of the belt system.

       - 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

          engine is running.

       - To prevent any belt-skip,which would cause mismatching of the valve timing

         between crank shaft and cam shaft.


    ▶ Chracteristic

       - Sealed groove bearing is uaually used and it also has built-in heat-resistant
