TOOTHED BELT

What is a toothed belt?

A timing belt, also known as a synchronous belt, is a type of mechanical belt drive used to synchronize the rotation of two or more pulleys. It plays an essential role in ensuring traction and power transmission in various mechanisms. They are generally made of rubber or polyurethane and feature teeth that fit into corresponding grooves on the pulley. This allows them to turn without slipping and reduces friction between them. This type of belt is quite flexible, enabling it to absorb shocks, which are common in high-performance applications.

Toothed belts are often confused with timing belts, but it's important to know that they're not the same thing. Toothed belts are trapezoidal in shape, while timing belts are flat.

What are the different types of toothed belts?

This product range is widely used in industrial, automotive and mechanical applications. Today, we offer two main types of timing belts:

• Simple toothed belts
• double toothed belts 

Both single and double timing belts are generally available in the following pitches:

• 2.5mm pitch (reference T2,5)
• 3mm pitch (reference 3M)
• 5mm pitch (reference 5M - T5)
• 8mm pitch (reference 8M)
• 10mm pitch (reference T10)
• 14mm pitch (reference 14M)

You can differentiate between single and double timing belts by reference. Double timing belts have a "D" in their reference number.

How to choose your toothed belt?

Selecting the right timing belt for your application is crucial to ensuring optimum performance. To this end, this product can be identified by its part number or by its dimensions. If your belt is in good condition, its part number will be written directly on it. You can then enter it in the search bar on the site to identify and order it. On the other hand, if the belt is in poor condition and the reference is not legible, you'll need to take the dimensions.

Before taking the dimensions, you'll need to determine the profile of your belt. Is it a single- or double-tooth belt? A simple visual check will enable you to answer this question. Next, you'll need to consider the pitch between two teeth, as well as the length, width and number of teeth on the belt. To accurately measure the pitch and width of the belt, we recommend using a caliper. For length, you can use a MESSLAT or a tape measure.
