Tensioner &Idler bearings

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
