The AT20 profile is a metric timing belt tooth shape. With a 20 mm pitch, this belt is intended for drives where the pulley grooves are cut to the same AT20 specification. The 8400 mm length is the datum length for the belt. If your application calls for an AT20 profile and an 8400 mm length, this part number is the correct starting point.
