Replacement V-Belts and Timing Belts, Standard & Metric Sizes V-belts are used in a variety of industrial applications, including power transmission/driving, timing, sequencing and conveying. V-belts can be smooth, wedged, banded, cogged, notched or ribbed depending on the application.

These standard banded v belts are stocked in many length sizes and range from 2 bands wide up to 12 bands wide. Typically banded belts are used on severe vibration drives such as rock crushers, agricultural equipment, industrial compressors, generators and hydraulic pumps.

3VX is a wedge, cogged V-belt where single belts have a nominal thickness of 5/16" and a nominal top width of 3/8". The top width for banded belts varies 

The most accurate way to measure the circumference of a v belt is with a v belt measuring tool or using a cloth tape measure (Not a steel tape measure or ruler) 

Poly V Belts By Size ; 440J8. $14.95 ; 370J8. $12.95 ; 330J8. $10.95 ; 430J14. $18.95 ; 460J16. $18.95.

How do you read V-belt sizes? Typically, the inside length of a belt is 2 less for a 4L belt and 1-1/2 less for a 3L belt. For example, a 4L460 belt would be 46 long outside and 44 inside. Automotive belts begin with either 4L (12.5mm wide) or 3L (9.5mm).

There are three common V belt types: Classical V-belt (classified by their dimensions from A to E), Narrow V series (ranked by their sizes 3V, 5V, and 8V), and light-duty Fractional Horsepower belt (classified by their dimensions 2L, 3L, 4L, 5L). The letter X classifies their counterpart cogged belt.

Note: As clarified with Gates, if you know the diameter of the flat pulleys and the center distance between them, then you can calculate belt length. This will 

Also, keep in mind belts do stretch and unfortunately there is no specific value for how much a belt can stretch. You'll also need to measure the width and depth to determine which section v

First, to determine what type of belt is on your fan, measure the width of the belt. Most fan belts are A type belts with a measurement of 1/2″.
