Tensioner Bearing

 Tensioner FunctionIt is rotated with a peanut hole as the central figure;1.       Easy install of timing belt2.       Set up initial belt tension with tension spring force3.       It keeps up belt tension after installing on engine 4.       Reduce belt span vibration as supporting belt

Idler Bearing

Idler FunctionMost of case, It locates tight (right) side;1.       Increase belt wrap angle of cam pulley and crankpulley2.       Reduce belt span vibration as supporting belt3.       It keeps up belt tension after installing on engineldler could be added or removed according to engine layout

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.

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 BearingUnitized 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.
