Frequently Asked Questions
What is D1900-S3M-420 used for?
D1900-S3M-420 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 D1900-S3M-420?
D1900-S3M-420 has a 3 mm tooth pitch, 140 teeth, a belt width of 190 mm, and a 420 mm (Pitch Length). The pitch length is the pitch-line circumference.
What does the DS3M in D1900-S3M-420 mean?
DS3M is a HTD (curvilinear) synchronous tooth profile. The belt must match the pulley, so a DS3M belt runs only on DS3M pulleys.
