Most belt order problems come from a wrong size. A PTFE belt is made to your machine, and a small error makes it slip or break. This guide explains how to measure a PTFE belt step by step, whether or not you have the old belt. It is based on more than 10 years of making PTFE belts in Egypt.

What measurements do you need?

For a closed-loop belt you need the total loop length and the width from edge to edge. For mesh belts, also tell us if you need a metal joint. For adhesive tape, you need the length, width and thickness.

Method 1: you have the old belt

  1. Remove the belt carefully.
  2. Lay it flat on a level surface without stretching it.
  3. Measure the full loop length (the circumference). If you measure it folded flat, tell us it was measured folded so we can calculate correctly.
  4. Measure the width at several points and note the largest.
  5. Photograph the belt and any joint.

Method 2: no old belt

  1. Measure the distance between roller centres.
  2. Measure each roller diameter.
  3. Measure the belt path width.
  4. Photograph the machine from several angles and send it to us.

We calculate the belt length with you from the drawing and measurements.

Method 3: adhesive tape on a jaw

Measure the jaw length and width exactly, leaving a small margin, and choose the thickness (80 to 180 microns) for your application.

Common measuring mistakes

  • Measuring a belt that is stretched on the machine.
  • Measuring length but forgetting width.
  • Relying on the machine model name instead of a real measurement.
  • Forgetting to mention a metal joint on mesh belts.
  • Rounding instead of measuring in millimetres.

What else to send

Machine type and model, operating temperature, what touches the belt (and whether it is food), and the quantity you need. The more accurate the information, the faster your quote.
