V-belts” as it sounds, was coined from the letter V looks of this particular belt. We can also say its name is gotten from its trapezoidal 

A joined V-belt is, in essence, a number of single V-belts joined together with a continuous tie-band across the back (see Figure 8). Figure 8 — Joined V-belt. A joined V-belt increases lateral rigidity to reduce belt whip and maintain stability under shock loads. It also simplifies installation and tensioning compared with multiple single belts.

contain the required number of belts. Maximum up to 5 belts in one tie band, depending upon the drive conditions, are recommended. Applications :.

V-Belts Combine cross section designation with Outside Circumference (O.C.) to the nearest whole number, plus a zero to determine Belt Part Number. Example: 5/8" top width 5VX belt with 80" O.C. equals 5VX800 V-Belt. X designates molded notch construction. Combine cross section plus Inside Circumference (I.C.) to determine belt part number.

If you measure the outer circumference, then you would subtract the number of inches based on the section you have (Listed below) to obtain the v belt number. This is also the same for the banded belts. Measure each individual band for banded belts to obtain the correct width. Examples of how belt numbers are coded per section:

The "V" designation in the prefix is a difference in the profile of the belt. Never substitute or mix these belts. They do not fit properly into pulleys designed for 3L and AX belts. They do not make full contact against the bottom and walls, and therefore will fail to perform.

2022. 7. 15. · This means the elastomer core is exposed and in contact with the surface of the pulley. The elastomer core has a higher coefficient of friction than the fabric-covered ones,

What do V belt numbers mean? The number following it is the outside length of the belt in tenths of inches. The inside length of the belt is typically 2″ less for a 4L belt, and 1-1/2″ less for a 3L belt. An example would be 4L460, which would be 46″ long outside, 44″ inside. The number following it is the inside length in inches.

Description. A1280/A49 V-BELT Width: 13mm. The most widely used V-belts are Z, A, B, C and D classical belt. Used more out of habit and convenience than design, these belts can handle fractional to 375 kW drives, usually at the lowest cost. However, they occupy more space, and the drives weigh more than narrow-belt drives.

V-belt cross sections can be identified by their top width and depth dimensions. For example, a v-belt with a top width of 21/32” and a depth of 7/16” is a “B” 

It consists of the normal profile size designation letter and a number that normally corresponds to the inner length in inches (rounded, where necessary); for example, "Z 22" or "D 150". [ source] A list of these numbers can be found on this v-belt index. Measuring v-belt profiles

Read the number that follows the letter. This number represents the length of the inside of the fan belt (as opposed to the number in the standard automotive 

Standard v belts are manufactured from a special formulated rubber and reinforced high strength polyester cords for uniformity & strength. These are used in many industries such as industrial, agricultural, material handling, HVAC and much more. The width ranges from 1/2" up to 1-1/2" and lengths from 16" up to 400".
