Common imperial pitches include

MXL
XL
L
H
XH
XXH

Each pitch is designed for specific torque and load capacities, making correct selection essential.

Key Benefits

Positive drive with zero slippage
Precise shaft synchronisation
High efficiency power transmission
Reduced maintenance compared to chain drives
Smooth, low-noise operation
Long service life

Imperial synchronous belts are widely used where consistent positioning and repeatability are critical.

Available Sizes & Specifications

When selecting an imperial timing belt, key factors include:

Pitch type (e.g., XL, L, H)
Belt length (in inches)
Belt width (in inches)
Tooth profile
Construction material (neoprene, polyurethane)
Tensile reinforcement type

If you have an existing belt code, it typically includes pitch and length information for easy identification.

Imperial Timing Belts FAQs

Are imperial and metric timing belts interchangeable?

No. Imperial belts use inch-based pitch measurements, while metric belts use millimetres (e.g., 5M, 8M, 14M). They are not interchangeable, even if they appear similar in size.

How do I identify my imperial timing belt size?

You will need to confirm:

Belt pitch (e.g., XL, L, H)
Belt length (in inches)
Belt width (in inches)

Most belts have a printed code that includes this information. If the marking is worn, measuring tooth pitch and belt length can help determine the correct replacement.

What causes imperial timing belts to fail?

Common causes of failure include:

Incorrect belt tension
Pulley misalignment
Overloading
Contamination from oil or debris
Mixing metric and imperial components

Routine inspection and proper installation significantly extend belt life.
