What Are Metric Timing Belts?

Metric timing belts (also known as metric synchronous belts) feature precision-moulded teeth that mesh perfectly with corresponding pulley grooves. Unlike V-belts or flat belts, timing belts eliminate slippage, ensuring exact rotational synchronisation between shafts.

They are commonly manufactured in metric pitches such as:

3M
5M
8M
14M
20M

These pitch designations refer to the distance (in millimetres) between belt teeth, allowing accurate specification for industrial machinery.

Need Help Selecting the Right Belt?

Choosing the correct timing belt ensures optimal performance and longevity. If you require help identifying pitch, length, or load capacity, our technical specialists are ready to assist.

Metric Timing Belts FAQs

What do 5M, 8M and 14M mean on a timing belt?

The “M” refers to metric pitch. For example:

5M = 5mm pitch
8M = 8mm pitch
14M = 14mm pitch

The pitch indicates the distance between belt teeth and must match the pulley exactly.

What is the difference between metric and imperial timing belts?

Metric timing belts use millimetre pitch measurements, while imperial belts use inch-based pitch measurements. They are not interchangeable, and mixing the two can cause premature wear or drive failure.

How do I identify the correct timing belt size?

You will need:

Tooth pitch (e.g., 8M)
Belt length (in mm)
Belt width (in mm)
Tooth profile (HTD, STD, etc.)

If the belt code is visible, it usually contains this information.
