About Sizing Belts

V-Belts

The trapezoidal shape allows these belts to wedge into pulleys in the presence of misalignment.

Precision-Matched V-Belts

Ensure even load distribution on drives with multiple 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.

Made-to-Order V-Belts

If none of our standard V-belts have the outer circumference you require, tell us what size you need and we'll make one for you.

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.

Cogged V-Belts for Variable-Speed Pulleys

A wide profile allows these belts to ride up and down the groove in variable-speed pulleys to handle a wide range of speed ratios.

Ultra-Flexible Banded V-Belts

An extremely thin profile gives these belts the flexibility to bend around small-diameter pulleys.

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.

Adjustable-Length V-Belting

Twist-Lock Adjustable-Length V-Belting

Twist the tabbed links together to form a belt. Because it’s made of individual links, this belting allows you to change your belt length without dismantling your drive.

Cut this perforated belting to length and screw a connector into the holes. Because you can quickly increase or reduce its length, it is often used to make replacement V-belts.

Press-Lock Adjustable-Length V-Belting

Steel rivets hold the individual links together. Use an installation tool to add or remove links.

V-Belting

Profile-Top V-Belting

A range of specially shaped tops carry materials in conveying applications.
