OEM supplier Automotive TOYOTA car belt tensioner pulley bearing RV6313

The Brief Description of Tensioner Bearings: 

Tension bearing widely used in automobile engines,to adjustment the tense force of transmission belt,the operating temperature up to 95 degrees,usually combined of deep groove ball bearings,castings,and pressed flange shaft.These bearings have compact structure,and correct positioning,installation,adjustment conveniently.

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 Bearing
Unitized with the pulley.

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

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