Cinghie Dentate - Cinghie - ATTI

Toothed Belts

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

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

They are ideal for applications that require positioning accuracy, reliability, and long service life, even under harsh operating conditions. They reduce maintenance and improve energy efficiency, making them perfect for machine tools, INDUSTRIAL AUTOMATION, material handling, and any application that requires a reliable and precise drive system.

Available in a wide range of versions, they include:

Metric T, AT, and HTDBelts for standard, high-precision applications and high-power transmission.
Belts in inches (XL, L, H, XH, and XXH), compatible with American-standard machinery (imperial pitch).
Options reinforced with a steel or Kevlar core for superior performance.

Metric closed-loop Belts with T-pitch, AT-pitch, and HTD-pitch, with lengths ranging from 920 to 3850 mm and widths up to 170 mm!

This type of Belts, thanks to its teeth and when paired with pulleys with the same pitch, enables synchronous power transmission, creating what is known as a “positive drive” free of slippage—ideal for high power applications.

Belts

Metric open-end Belts sold by the meter with T, AT, and HTD pitches are designed for applications where it is not possible or practical to install a Belt .

Unlike Belts , these Belts run all the way around the pulleys. They are secured using clamping blocks with the same pitch as Belt, which hold it firmly in place without the need for permanent splices.

This solution is ideal for linear positioning movements, industrial automation, cutting machines, and material-handling systems where precision and ease of adjustment are required.
