Toothed Belts

Metrical pitch AT, T, HTD / Inch pitch L, XL, H, XH, XXH

The synchronous belts ensure quiet, efficient, and slip-free power transmission, thanks to the toothed profile that meshes perfectly with pulleys of the same pitch. 

They are ideal for applications requiring positioning precision, reliability, and long life even in heavy-duty working conditions. They reduce maintenance and improve energy efficiency, making them perfect for machine tools, industrial automation, handling, and any application requiring reliable and precise transmission.

Available in a wide range of versions, they include:

  • Metric T, AT, and HTD synchronous belts for high precision standard applications and high power transmissions.
  • Inch XL, L, H, XH, and XXH synchronous belts, compatible with American standard machinery (imperial pitch).
  • Reinforced options with steel or Kevlar core for superior performance.

Frequently asked questions

How is the code of an HTD timing belt read (e.g., 365-5M-15)?

The code of an HTD timing belt indicates the length, pitch of the teeth, and width of the belt.

Taking 365-5M-15 as an example:

  • 365: belt length in millimeters.
  • 5M: tooth pitch of 5 mm, with HTD profile.
  • 15: belt width in millimeters.

To calculate the number of teeth, simply divide the length by the pitch: 365 ÷ 5 = 73 teeth.

On shop.atti.it, ATTI offers over 4,200 timing belts, in HTD pitches of 3M, 5M, 8M, and 14M and in metric profiles.

What is the difference between HTD, T, and AT timing belts?

The HTD, T, and AT timing belts are primarily distinguished by their tooth profile and transmission characteristics.

  • HTD (3M, 5M, 8M, 14M): have rounded teeth and are particularly suitable for transmitting high torque.
  • T (T2.5, T5, T10): have trapezoidal teeth and a metric pitch. They are widely used in handling and positioning applications.
  • AT: have an enhanced trapezoidal profile compared to T belts and allow for greater force transmission at the same width.

Note: the belt and the pulley must have the same profile and the same pitch. Different types are therefore not directly interchangeable.

To choose the most suitable belt, it is important to verify the transmission characteristics and compatibility with the pulleys used.

What are the Gates Poly Chain Carbon belts and when are they used?

The Gates Poly Chain Carbon are polyurethane toothed belts with carbon fiber tensile cords, designed to transmit very high torque.

They are used in industrial applications that require robust and efficient drives and can be an alternative to traditional roller chains.

Compared to chains, they offer several advantages:

  • No lubrication is required.
  • They have a very low elongation during operation.
  • They allow the creation of drives suitable for high loads.

Caution: the Gates Poly Chain Carbon require pulleys with a dedicated profile and are not directly interchangeable with standard HTD toothed belts.

On shop.atti.it, ATTI offers over 250 codes from this range, including the Mini Poly Chain version.

Can open timing belts be purchased by the meter?

Yes. ATTI offers open timing belts by the meter in polyurethane, primarily used for linear shafts, conveyor belts, and positioning systems.

The belts can be ordered by the meter, with a minimum quantity of 5 meters.

In these applications, the ends of the belt are generally secured using special locking plates, available for the main pitches of the timing belts.

To identify the most suitable product, it is important to check the profile, pitch, and width of the belt.
