Cinghie Dentate - Cinghie - ATTI

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.

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

This type of belt, due to its tooth structure and paired with pulleys of the same pitch, allows synchronous transmission, achieving what is known as a "positive drive" without slipping, ideal for high powers.

Pitch AT

Closed loop timing belts with Pitch AT metric type

Pitch T

Closed loop timing belts with Pitch T metric type

Type T pitch
Widths from 6 to 50 mm
Length from 120 to 2250 mm

Pitch HTD

Open Belts

Metric timing belts open ended with pitch T, AT and HTD are designed for applications where it is not possible or practical to install a closed loop belt.

Unlike closed loop belts, these belts do not loop completely around the pulleys. Their attachment occurs via clamping blocks that feature the same pitch as the belt, which holds it firmly in place without the need for permanent joints.

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