How to measure timing-belt length before asking for a quote

Timing-belt RFQs slow down when buyers only report an approximate outside loop. For synchronous belts, the useful starting point is usually pitch length, tooth count, and the actual pulley profile running on the machine.

If the old belt marking is readable, start there first. Many timing-belt references already contain pitch family, tooth count, or finished length logic. When the marking is unclear, count teeth, confirm pitch family, and photograph the pulley tooth form whenever possible.

Open-end and endless belts must not be mixed in the same assumption. A machine may use a fabricated open-end PU belt on one axis and a molded endless belt on another. Length discussion only becomes accurate when the supply form is stated clearly.

The fastest quote package is simple: existing marking, tooth profile, width, tooth count or pitch length, pulley photos, and whether the belt also carries product. That gives engineering enough to move from a rough description to a belt that can actually be made.
