Optimized structure design parameters, sealing structures with good performances and good greases are used in tensioner bearings to ensure the safe and reliable running of bearings under a dusty envirnment.Different sealing structures and greases are used respectively according to temperature differences during operation of tensioner bearings to meet the requirements of performances.

Tensioner Function

It is rotated with a peanut hole as the central figure:

Easy install of timing belt
Set up initial belt tendion with tension spring force
It keep up belt tension after installing on engine
Reduce belt span vibration as supporting belt
Idler Funbtion

Incease belt wrap angle of campulley and crank pulley
Reduce belt span vibration as supporting belt
It keep up belt tension after installing on engine
