A/C Compressor Drive Belt
The outward appearance of the belt (1) is similar to the current design serpentine belt. The reinforcing cord provides its unique qualities. The belt cord is made of a polyamid material. The polyamid cord is more elastic than the more traditional aramid or polyester cord designs. A tensioner is not needed.
Polyamid cord, when combined with a more elastic backing compound, ensures the belt is able to maintain the specified tension within the specified range of usage.
