Step 2
What Type of V-Belt Are You Looking for?
Classic sheathed belt
Raw-edge cogged V-belt
Variable speed belt = wide V-belt
Multiple V-belt = poly-V-belt
Step 3
What Is the V-Belt Width – respectively, What Is the V-Belt Profile?
The same procedure applies to both sheathed and cogged V-belts.
Measure the upper width of the belt, e.g. 17 mm (belt type 17/B)...
... or e.g. 16.3 mm (belt type SPB or XPB for belts with teeth).
Measure the belt thickness, e.g. 13 mm (belt type SPB 16.3×13)...
... or e.g. 10 mm (belt type 17/B with a measurement of 17×10).
In the profile table, you can find the appropriate type.
Step 4
What Is the V-Belt Length?
Measure the length of the belt, e.g. encircle the outer surface with a string.
Then measure the length of the string.
V-Belt Lengths
- Li – inner length measured by the inside surface
- La – outer length measured by the outside surface
- Ld – working length
More Tips for V-Belt Identification
Newer belts are marked with a product number and/or manufacturer.
High performance cogged belt types XPZ, XPA, XPB, XPC.
ContiTech belts have cut sides.
Vertical strands of fibreglass can be seen on the sides.
A multiple belt is actually V-belts joined together.
Transmitted power is the same, but multiple belts are 100 % in set and do not oscillate.
