Phase 1: Identify the Guide Bar Type

There are two primary types of guide bars. The measurement process is slightly different for each.

Type A: V-Guide (or “V-Belt”)

This is a triangular-shaped guide that runs in a V-groove pulley. It’s the most common type.

Type B: Tracking Strip (or “Bead”)

This is a rectangular or trapezoidal strip, often used to trip a sensor or run against guide wheels on the side of the belt.

How to Measure a V-Guide

You need three key dimensions: Height, Width, and Angle.

1. Height (H):
   • Place the straight edge across the top of the belt, spanning the guide bar.
   • Use your caliper or a ruler to measure the distance from the bottom of the straight edge to the highest point of the V-guide.
   • This is the most critical dimension. It must fit snugly into the V-groove pulley without bottoming out or being too shallow.
2. Width (W):
   • Measure the total width of the guide bar at its base, where it meets the belt.
   • Do not measure the top of the “V”; measure the widest point.
3. Angle (θ):
   • Most common V-guides have a standard 60-degree or 90-degree angle.
   • You can use a protractor or an angle finder tool.
   • Pro Tip: If you don’t have tools, measure the height (H) and the top flat width (if any). A 90° guide will have a height almost equal to half its base width. A 60° guide will be taller and sharper. A profile gauge is perfect for this.

How to Measure a Tracking Strip

You need two key dimensions: Height and Width.

1. Height (H):
   • Just like with the V-guide, use a straight edge and caliper to measure from the belt surface to the top of the strip.
2. Width (W):
   • Measure the width of the strip at its base.
   • Note if the sides are perfectly vertical (square) or slanted (trapezoidal).

Phase 2: Additional Critical Information

When you order a new belt or a guide bar to be applied, you will also need:

1. Belt Thickness: Measure the overall thickness of the conveyor belt itself.
2. Belt Ply and Material: Is it a PVC, rubber, urethane, or modular plastic belt? This determines compatibility with the guide bar material.
3. Guide Bar Placement:
   • On the Top or Bottom? Is the guide on the carrying side or the pulley side of the belt?
   • Distance from Edge: How far is the center of the guide bar from the edge of the belt?
   • Continuous or Segmented? Is it one long strip, or is it applied in segments with gaps?

Pro Tips and Common Mistakes to Avoid

• Don’t Guess the Angle: Assuming the angle is the most common mistake. A 60° guide in a 90° pulley will not track properly and will wear out extremely fast.
• Measure in Multiple Places: Belts and guides can wear unevenly. Take measurements at several points along the belt’s length (e.g., near the center and near both ends) to get an average.
• Use the Right Tools: A tape measure is better than nothing, but a Vernier caliper is inexpensive and provides the precision needed for a reliable measurement.
• Take Pictures: Use your smartphone to take clear, close-up photos of the guide bar from the side and top. Include a ruler or caliper in the shot for scale. This provides invaluable visual reference for the supplier.
