V-Belts
V-belts are used to transmit power between pulleys in industrial, agricultural, and automotive drives. Unlike flat belts, they feature a V-shaped profile, which increases friction in the pulley groove and allows for the transmission of higher power while maintaining compact dimensions. The basic construction consists of a rubber compound with tensile fibers, which ensure strength and dimensional stability under load.
The product range includes classic coated V-belts as well as cut V-belts, which offer greater flexibility and better heat dissipation during operation.
This category includes standard profiles manufactured according to common industrial size series. V-belts are available in several widths, which determine their compatibility with pulleys.

V-belt Types
Our product range includes standard coated V-belts, cogged V-belts and AVX automotive V-belts, which are used in industrial drives as well as in automotive powertrains, in drives for compressors, fans, pumps, or agricultural machinery. Select the desired type using the filter.
How to Choose a V-Belt
Determine the profile and length from the markings on the old belt. For each belt, we list the inner length Li, the calculated length Lw, and the outer length La; always compare the same type of length as on the old belt. You’ll find double-sided belts in the Double-Sided V-Belts category, and toothed belts in the Toothed Belts category.

Frequently Asked Questions
How do I read a V-belt designation?
The designation includes the profile (e.g., SPZ) and the length in millimeters. Determine whether the length listed is the inner (Li), calculated (Lw), or outer length (La).
What is the difference between the SPZ and XPZ profiles?
Both are 9.5 mm wide; the XPZ has teeth on the inner side.
How can I identify a belt profile without a marking?
Measure the width of the belt on the top side and look it up in the profile table above.
