There are various types of V-belt, each with its own specific characteristics and applications. Commonly used types include classic V-belts, narrow V-belts, bare fanc V-belts and hexagonal V-belts.

In this V-belt buying guide, we'll explore each belt type in detail, focusing on their benefits, recommended uses and key factors to consider when selecting them.

I. Why choose a classic V-belt?

 

Design:

 

Historically, these belts were the first to appear on the drive market. They are specially designed for maximum performance in industrial machinery.

  • Textile cover for optimum flexibility and abrasion resistance
  • Rubber compound with polyster tensile cords

 

Benefits :

 

Assured stability and resistance to contact with mineral oils

Complies with ISO standards

Excellent ratio between traction and transmission.

 

Applications:

 

Belts are frequently used in vehicles, agricultural and production machinery, linear drive systems, servomotors, DC motors, printing systems and textile manufacturing to transfer power and positioning.

II. Why choose a narrow V-belt?

 

Design : narrow

 

This belt combines maximum transverse rigidity with great flexibility in the direction of travel.

The design of a narrow V-belt is similar to that of conventional V-belts, except that the pitch is shorter (i.e. the profile is narrower). These belts are therefore made of rubber with fabric cords covered by a protective layer. The number of cords is increased according to the force required.

 

Advantages :

 

  • Ideal for applications requiring very small dimensions
  • Compared with conventional V-belts, narrow V-belts offer greater flexibility, enabling designers to use more complex designs.

 

Applications:

 

These higher-height belts offer stronger adhesion to pulleys than the standard version. They are ideal for higher power transmissions and applications requiring high tensile strength and durability, such as material handling systems, conveyor systems and transportation.

They are also very popular in applications where compact size and small footprint are crucial, such as computer systems, industrial machinery and electronic devices.

III. Why choose a narrow toothed V-belt (bare side)?

 

Design:

 

Narrow toothed V-belts are a variant of V-belts. They differ only in the teeth they use to adapt to V-belt pulleys. The notching in this belt gives it greater flexibility and better heat dissipation when speeds are high.

 

Advantages :

 

  • Optimized efficiency
  • They are more elastic and can be deformed to adapt to the movements of the notched pulleys.
  • They are easier to install and maintain.
  • These belts can be used with smaller pulley diameters and offer greater power. They are ideal for high-stress applications

Applications :

 

Narrow toothed V-belts are used in compact, high-performance drives and drives exposed to high shock loads, with small center-to-center distances and pulley diameters. They are suitable for the design of compact transmissions with high power ratings and limited space.

NB* : 3V, 5V, 3VX and 5VX belts are American belts, but compatible with European versions.

IV. Why choose a hexagonal V-belt?

 

Design:

 

Power equipment such as ride-on and walk-behind mowers, tractor mowers, tillers and motor mowers are equipped with a hexagonal belt, also known as a double belt, whose purpose is to efficiently transmit power from the engine to the blade.

 

Advantages :

 

  • Hexagonal belts improve machine operating comfort by reducing vibration
  • They are wear-resistant, produce less noise and last longer than traditional belts.
  • They are easy to install and require no special tools

 

Applications :

 

Hexagonal belts are designed for applications where the pulleys are on a common plane, where one or more of the driven pulleys rotate in different directions, they can be easily installed on trapezoidal or "v" pulleys.

Hexagonal belts are used in industries such as :

  • the textile industry
  • Agricultural industry
  • Horticultural industry - These belts can be used as deck belts on large grass-cutting equipment and ride-on lawnmowers.

PLEASE NOTE:

 

Belts from the same family run on the same pulleys. Example:

An SPZ pulley fits Z belts as well as SPZ, XPZ, 3V and 3VX belts
