The double-sided pitch synchronous belt and tooth profile is equivalent to a single tooth and tooth belt pitch.
Double teeth with tooth by the synchronous belt arrangement standards can be divided into two types;
DA-duplex synchronous belt tooth,
a tooth with its two symmetrical arrangement, see Figure (a)
DB-duplex synchronous belt gear,
with its two locations with staggered teeth were, see Figure (b)
