Types of V-Belts

What Are The Different Types Of V-Belts?

V-belts are one of the many different types of conveyor belts available. These belts are different from the other varieties because there is only one strand of V-belt found underneath the roller bed. This belt can be found on one of the sides of the rollers right next to the belt’s side-frame. These belts run in the opposite direction from that of whatever contents the V-belt is conveying. These types of belts are best for light or medium duty loads and are not the best in environments that are moist or oily. One of the great things about these belts is that in order for the belt to function, only very light contact between the belt and the bed rollers is necessary.

Types Of V-Belts

Although there are many options available when selecting the best v-belt for your business, there are two main types of belts, poly v-belts and variable speed v-belts. Poly v-belts are ideal for those who want a flexible belt that will offer smooth performance along with a low profile design and the capability to work at high speeds. The variable speed v-belt on the other hand can work with sheave drives of variable speeds and because of this it requires a great deal of lateral rigidity to help maintain a consistent speed control.

More Options

In addition to selecting between poly v-belts and variable speed v-belts, there are also other options you can make to customize your v-belt, making it unique. These belts can come in a wide variety of surfaces depending on what is required for the function they will perform. Some of the most common types of v-belts include ribbed ones, notched ones, cogged ones, banded ones, wedged ones and smooth ones, each of which is specifically designed to help serve a different purpose. The guides for the v-belts can also come in several types, mostly based on shapes and surface with the most common shapes being a triangle profile, a rectangle profile, a special rectangular profile (with rounded corners) and a special v-profile (a trapezoidal shape).

Normal Uses

V-belts are widely used because of their versatility as well as ability to handle directional changes that might prove challenging with other types of conveyor belts. They can be used for basic tasks such as product alignment, offsetting connections, diverting, merging and directional changes. Because of these functions, they are ideal for many industrial applications and are very common in power transmission/driving, conveying, sequencing and timing. The different types available are what make v-belts so versatile.


No matter which type of v-belt you select or what surface you opt for, there are several features that are common for all of these belts. They will all follow a belt path which eliminates the risk of bending back the belt and because of their abilities with directional changes they are usually available in tight radius configurations. They will almost always have automatic drive pressure and true taper rollers in addition to sleeves that allow them to move the product through curves quietly while still maintaining their orientation.
