Frequently Asked Questions

What is 250-S5M-870 used for?

250-S5M-870 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 250-S5M-870?

250-S5M-870 has a 5 mm tooth pitch, 174 teeth, a belt width of 25 mm, and a 870 mm (Pitch Length). The pitch length is the pitch-line circumference.

What does the S5M in 250-S5M-870 mean?

S5M is a STD (curvilinear) synchronous tooth profile. The belt must match the pulley, so a S5M belt runs only on S5M pulleys.
