Features
● Alternator serpentine belt linear belt speeds up to 60 m/s
● High strength and heat memory tensile cord is made of special material. With its features of high transmission efficiency and thermal shrinkage, it can keep the constant length and prolong the belt lifespan.
● High temperature resistance comparable to HNBR
● Cold resistance better than ASCM, HNBR and CR

Applications
The fan belt is a crankshaft drive belt, it's main purpose is to drive the engine and pump.
Fan belt wear analysis
① ABRASION
Appearance: The backside of the belt appears shiny or glazed. In advanced stages, the fabric or even the cord becomes exposed and gets damaged.
Cause: When in motion, the belt makes contact with a foreign object in its path such as a flange or bolt. This may be caused by improper belt tension or by belt flutter (vibrations) on longer span lengths between two pulleys.
Solution: Replace the belt and make sure to observe the complete tracking of the belt as it revolves around the pulleys. Check the tensioner and ensure proper belt tension.
② DAMAGED OUTERMOST RIBS
Appearance: Sidewalls of the belt may appear glazed or the edge-cord may become frayed and ribs removed. A noticeable noise may result. In severe cases, the belt can get pulled into the timing belt drive causing catastrophic engine damage.
Cause: Pulley misalignment is a common cause of premature belt failure. Misalignment forces the belt to kink or twist while running, causing premature wear.
Solution: Replace the fan belt and make sure to realign the pulleys. Also check that the pulleys, pulley brackets and shafts are not bent or broken.
