Bestorq DA540H double‑sided timing belt is a 1/2‑inch pitch, 54‑inch outside length industrial synchronous belt designed to transmit power from both belt faces. It employs fiberglass tensile members and a rubber outer material with a standard timing tooth profile, and belt widths within the DA540H/D540H family vary by variant (examples include 2 inches and 4 inches wide). This dual‑sided belt enables power transmission on both sides for synchronized drives where opposite rotation on each face is required.
