Industrial trapezoidal belts: power, safety, and long life

The industrial trapezoidal belts are designed for high-performance power transmission. Thanks to their function as a "mechanical fuse", in case of overload they allow controlled slipping that protects the kinematics and reduces the risk of failures.

Specifications and availability:

Metric trapezoidal belts, smooth or notched
Sections SPA, SPAX, SPB, SPBX, SPC, SPCX, SPZ, SPZX (metric) and A, AX, B, BX, C, CX, D, Z (inch) compatible with the respective pulleys
Metric and inch developments, with lengths up to over 15,000 mm
High-quality materials for reliability and long life

Ideal for industrial applications, machinery, and plants that require maximum efficiency and durability.

How to Calculate the Length (or Development) of a Trapezoidal Belt?

The length of the trapezoidal belt can usually be read directly from the stamping on it.

If the code on the belt cannot be read, for instance, due to wear, you can proceed to manual measurement and calculate the development according to the tables provided later.

It should be noted that for classic trapezoidal belts, the internal development is indicated as the standard reference, whereas for narrow trapezoidal belts, prefixed SP or XP, the primitive development is usually indicated.

To know the length of a belt, simply measure the EXTERNAL LENGTH manually, recording the measurement in millimeters, and then calculate the internal or primitive length based on the indications from the tables below.

After measuring the external length, which is usually easier and quicker to measure, simply subtract or add the values indicated in the table to the measured value in millimeters to obtain the actual development.

Examples

1) I measure the external length of a belt with section Z.

To find the internal development, simply subtract 38 mm from the measured value.

2) I measure the external length of a belt with section SPB.

To find the primitive development, simply subtract 22 mm from the measured value.

Normally, for classic trapezoidal belts, the inch is used as the unit of measurement, but to simplify calculations, we preferred to indicate all measurements also in millimeters.
