Frequently Asked Questions
What is 393-3M-320 used for?
393-3M-320 is a timing belt used on positive, no-slip drives such as conveyors, pumps, packaging machinery, robotics, and machine tools. Synchronous belts hold timing between shafts, so they suit applications where slip is unacceptable.
What are the dimensions of 393-3M-320?
393-3M-320 has a 3 mm tooth pitch, 131 teeth, a belt width of 320 mm, and a 393 mm (Pitch Length). The pitch length is the pitch-line circumference.
What does the 3M in 393-3M-320 mean?
3M is a HTD (curvilinear) synchronous tooth profile. The belt must match the pulley, so a 3M belt runs only on 3M pulleys.
