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.

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.

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.

Grip-Top Twist-Lock Adjustable-Length V-Belting

A textured PVC top layer helps convey material in slippery environments or up steep inclines.

Static-Control Twist-Lock
Adjustable-Length V-Belting

This belting limits static electricity discharge for hazardous applications such as fuel transfer and solar-cell manufacturing.

Screw-Connect Adjustable-Length V-Belting

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.

V-Belt Pulleys

Choose from nylon, UHMW, and zinc.

Heavy Duty V-Belt Pulleys

These pulleys are cast iron.

Adjustable-Pitch V-Belt Pulleys

Increase efficiency, vary speed, and extend the life of your drive by changing the pitch on these pulleys.

Constant-Tension V-Belt Pulleys

A built-in spring maintains tension on your belt.

Quick-Disconnect (QD) Bushing-Bore V-Belt Pulleys

Use these pulleys with compatible quick-disconnect bushings.

Split-Tapered Bushing-Bore V-Belt Pulleys

These pulleys have the same sizing versatility as quick-disconnect pulleys, but they create a tighter grip on bushings for use in high-torque applications.

V-Belt Idler Pulleys

These pulleys spin freely on built-in ball bearings to maintain tension for reduced wear and vibration.

V-Belt and Pulley Trade Size Identifiers

Measure V-belt cross sections and pulley groove depths to select the correct size belt.
