INTRODUCTION
V-belts are one of the most commonly used power 
transmission belts, popular for their ability to transmit high 
torque efficiently while reducing slippage. They have been in 
use for over a century and are still widely used today. There are 
several types of V-belts available in the market, and it is 
essential to understand the differences between them to 
choose the right one for your application. In this blog post, we 
will discuss the various types of V-belts and their applications.
1. Classical V-belts
Classical V-belts are the most common type of V-belts, also 
known as standard V-belts. They have a trapezoidal cross-section 
and come in different sizes, designated by letters. The most 
common sizes are A, B, C, D, and E. Classical V-belts are suitable 
for low to medium power transmission applications and are 
commonly used in agricultural machinery, HVAC systems, and 
other general-purpose applications.
2. Narrow V-belts
Narrow V-belts, also known as Micro V-belts, have a 
narrower cross-section than classical V-belts. They are 
designed for high-speed, high-torque applications and are 
commonly used in automotive applications such as power 
steering pumps, air conditioning compressors, and 
alternators. They also have a longer service life and are more 
efficient than classical V-belts.
3. Double V-belts
Double V-belts, as the name suggests, have two V-shaped 
grooves on their inner surface. They are designed to transmit 
higher power than classical V-belts and are commonly used 
in industrial applications such as machine tools, 
compressors, and pumps. Double V-belts offer better 
stability and reduced vibration compared to classical V-belts.
4. Cogged V-belts
Cogged V-belts have a notched or toothed design on their inner 
surface, which increases their surface area and allows for 
better flexibility. This design also reduces slippage and 
increases power transmission efficiency. Cogged V-belts are 
suitable for high-torque, high-speed applications and are 
commonly used in lawn mowers, snow blowers, and other 
small engine applications.
5. Raw Edge V-belts
Raw edge V-belts have a flat top surface, which increases 
their surface area and allows for better power 
transmission. They are suitable for high-speed, high-
torque applications and are commonly used in automotive 
applications such as engines and transmissions. Raw edge 
V-belts are also more durable and have a longer service 
life than classical V-belts.
6. Variable Speed V-belts
Variable speed V-belts are designed to operate 
efficiently at different speeds. They have a tapered 
cross-section that allows for better flexibility and adapts 
to different pulley diameters. They are commonly used 
in industrial applications such as conveyors, 
compressors, and generators.
7. Banded V-belts
Banded V-belts consist of several classical V-belts joined 
together with a band. This design offers better stability 
and reduces vibration compared to classical V-belts. 
Banded V-belts are suitable for high-torque, high-speed 
applications and are commonly used in industrial 
applications such as pumps, compressors, and 
generators.
8. Kevlar V-belts
Kevlar V-belts are made from Kevlar fibers, which are 
known for their strength and durability. They are 
suitable for high-torque, high-speed applications and 
are commonly used in industrial applications such as 
agricultural machinery, lawn mowers, and snow 
blowers. Kevlar V-belts offer better resistance to 
abrasion and heat compared to classical V-belts.
CONCLUSION
In conclusion, V-belts come in various types and sizes, 
each with its unique features and applications. Choosing 
the right V-belt for your application is essential to 
ensure optimal performance and longevity.
