HTD Pulley for Metal Detectors

Introduction to HTD Pulley

HTD pulleys, or High Torque Drive pulleys, play a crucial role in metal detectors and other machinery. These pulleys ensure smooth and efficient power transmission, making them indispensable for various industrial applications.

What is an HTD Pulley?

An HTD pulley features a unique tooth profile that provides higher torque capacity. The rounded teeth ensure better engagement with the belt, reducing slippage and wear.


These pulleys are typically made from durable materials such as aluminum, steel, or reinforced plastic, ensuring longevity and resistance to environmental factors.


Used in various applications, HTD pulleys are ideal for metal detectors due to their ability to handle high torque loads efficiently. They are also used in robotics, automotive, and industrial machinery.

What is the Minimum Pulley Size for HTD 5M?

Minimum Diameter

The minimum pulley diameter for HTD 5M belts is typically around 19.05mm. This ensures the belt can bend without excessive stress, maintaining performance and longevity.

Tooth Count

For HTD 5M belts, the pulley should have at least 10 teeth. This minimizes the risk of belt slippage and ensures smooth power transmission.


Proper spacing between pulleys is essential to prevent excessive belt tension or slack, which could lead to operational issues or premature wear.

What is the Difference Between GT and HTD Belts?

Tooth Profile

The primary difference lies in the tooth profile. GT belts have a modified curvilinear tooth design, providing a more precise fit and reducing backlash compared to HTD belts.

Load Capacity

GT belts generally offer higher load capacity and greater efficiency, making them suitable for more demanding applications. However, HTD belts are still highly effective for a wide range of uses.


GT belts are known for their flexibility and ability to handle more compact pulley diameters, which can be advantageous in space-constrained applications.

How to Choose or Customize an HTD Pulley

Load Requirements

Determine the torque and load requirements of your application to ensure the pulley can handle the operational demands without failure.

Material Compatibility

Select a material that is compatible with the operating environment. For instance, aluminum is lightweight and corrosion-resistant, while steel offers superior strength.

Size Specifications

Specify the pulley size, including diameter and width, to match the belt and ensure proper fitment and function within your machinery.

Custom Tooth Profiles

For specialized applications, consider custom tooth profiles to optimize performance. This can enhance engagement and reduce wear on both the pulley and belt.

Environmental Conditions

Account for environmental factors such as temperature, humidity, and exposure to chemicals. This will guide material selection and any necessary protective coatings.
