Multiple V-Belts – Procedure for Belt Identification
Step 2 - What type of V-belt are you looking for?

A multiple belt is actually V-belts joined together.

Classic sheathed belt, e.g. SPB/5V...

... or raw-edge cogged V-belt, e.g. XPB/5VX.
Step 3 - What is the belt width - respectively, what is the belt profile?

The same procedure applies to both sheathed and cogged V-belts.

Measure the belt profile, i.e. the width...

... and thickness. Accordingly, determine the profile.

Measure the entire belt width in mm.

Calculate the number of ribs and measure their pitch.
In the profile table, you can find the appropriate type.
Step 4 - What is the belth length?

Measure the length of the belt, e.g. encircle the outer surface with string.

Then measure the string in metres.
Belth lengths:
- inner length Li - measured by the inside surface
- outer length La - measured by the outside surface
- working length Lw - working length
More tips for belts identification

Newer belts have markings, identifying product number and manufacturer.
In case of repeated belt damage or breakage, it is necessary to remove the belt and determine its fault.
