What are the dimensions of 690-3M-450-SLV?
690-3M-450-SLV has a 3 mm tooth pitch, 230 teeth, a belt width of 450 mm, and a 690 mm (Pitch Length). The pitch length is the pitch-line circumference.
What does the 3M in 690-3M-450-SLV mean?
3M is a HTD (curvilinear) synchronous tooth profile. The belt must match the pulley, so a 3M belt runs only on 3M pulleys.
