Imperial Timing Belt Pulleys – Precision Synchronous Drive Components

At Bolton Engineering Products Ltd we stock imperial timing belt pulleys in high grade steel for accurate and efficient synchronous power-transmission. Designed to correspond with imperial pitch timing belts, these pulleys provide accurate speed ratios and resistance to wear on industrial and automotive applications.

If you are seeking dependable imperial timing products in the UK, we have the reliable stock at competitive prices available for prompt shipping.

How to Correctly Measure an Imperial Timing Pulley?

Use the following method to determine the dimensions of an imperial timing pulley:

  • Locate the pitch (ex: XL 1/5, L 3/8", H 1/2")
  • Count the number of teeth
  • Measure the outside diameter (OD)
  • Ensure Keyway and Bore Size.
  • Check the width of pulley to fit with the belt

Proper measurement will ensure that the belt you purchase will fit your equipment and not burn up too quickly or be too lose.

What Are the Best Imperial Timing Belt Pulleys for Automotive Use?

For automotive and performance systems, the best pulleys offer:

  • Accurate tooth profile for positive engagement
  • High-strength aluminium or steel construction
  • Corrosion resistance
  • Smooth, low-noise operation
  • Precision bore tolerances

Imperial timing belt pulleys are commonly used in camshaft drives, supercharger systems, and auxiliary belt systems where timing accuracy is critical.

What Are the Standard Imperial Timing Belt Pulley Sizes?

Common imperial timing pulley profiles include:

Profile

Pitch

Common Applications

XL

1/5" (0.200")

Light-duty automation

L

3/8"

Industrial machinery

H

1/2"

Heavy-duty drives

XH

7/8"

High torque systems

Each pulley must match the exact imperial timing belt profile to ensure correct meshing.
