Descriptions:
The Serpentine Belt is also called an accessory Belt, fan Belt, and Drive Belt. The belt is long and snakes through several pulleys. It allows the Belt to pass over more than three pulleys with a large enough wrap angle to avoid slipping, idler pulleys that press against the back of the belt are included, forcing the belt into a serpentine shape.

Attributes:
• Provide 12 ribs for a better grip and reduce slippage.
• Effective Length of the Belt will be 2128 ± 5mm. 
• Flexible materials such as rubber or synthetic polymers, which allow them to bend and wrap.
