3950-S3M-330 has a 3 mm tooth pitch, 110 teeth, a belt width of 395 mm, and a 330 mm (Pitch Length). The pitch length is the pitch-line circumference.
What does the S3M in 3950-S3M-330 mean?
S3M is a STD (curvilinear) synchronous tooth profile. The belt must match the pulley, so a S3M belt runs only on S3M pulleys.
