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.
