Frequently Asked Questions
What is 1863-3M-12 used for?
1863-3M-12 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 1863-3M-12?
1863-3M-12 has a 3 mm tooth pitch, 621 teeth, a belt width of 12 mm, and a 1863 mm (Pitch Length). The pitch length is the pitch-line circumference.
What does the 3M in 1863-3M-12 mean?
3M is a HTD (curvilinear) synchronous tooth profile. The belt must match the pulley, so a 3M belt runs only on 3M pulleys.
