D770H129 has a 12.7 mm tooth pitch, 154 teeth, a belt width of 1.29 in, and a 77 in (Pitch Length). The pitch length is the pitch-line circumference.
What does the DH in D770H129 mean?
DH is a HTD (curvilinear) synchronous tooth profile. The belt must match the pulley, so a DH belt runs only on DH pulleys.
