D300L525 has a 9.525 mm tooth pitch, 80 teeth, a belt width of 5.25 in, and a 30 in (Pitch Length). The pitch length is the pitch-line circumference.
What does the DL in D300L525 mean?
DL is a HTD (curvilinear) synchronous tooth profile. The belt must match the pulley, so a DL belt runs only on DL pulleys.
