V-Belts
2L, 3L, 4L, and 5L V-belts are commonly used on light duty drives with fractional-horsepower motors. A, B, and C V-belts are for medium and heavy duty drives.

Precision-Matched V-Belts
Ensure even load distribution on drives with multiple belts. These are matched to the trade size within a tight tolerance for better performance and reduced wear compared to standard A- and B-section V-belts.

High-Capacity Narrow-Wedge V-Belts
A narrow belt profile transmits up to three times the horsepower of standard V-belts for use on heavy duty drives with shock loads.

Cogged V-Belts
More flexible than smooth V-belts, these have notches that allow them to bend around small-diameter pulleys and accommodate twists and turns on curved drives.

High-Capacity Narrow-Wedge Cogged V-Belts
A narrow belt profile transmits up to three times the horsepower of standard cogged V-belts for use on heavy duty drives with shock loads. Notches increase flexibility for bending around small-diameter pulleys and dissipate heat for a long service life.

Banded V-Belts
Also known as serpentine belts, these have multiple bands that function as a single unit for consistent drive performance and even load distribution. They handle shock loads better than standard belts.
