AT Polyurethane Open-Ended Timing Belts
Polyurethane open-ended timing belts in ATThe AT profile is a further development of the T (Trapezprofil) profile. The teeth have a higher load capacity because of the increased tooth volume. The optimized flank angle results in improved tooth meshing. Here, too, a play-free belt/sprocket pairing that results in unsurpassed precision can be achieved. profile are made of thermoplastic polyurethane, which has high dimensional stability and wear resistance, and steel tensile fiber, in special cases aramid or stainless steel.
The open-ended belts can be welded into endless belts.

Belts Fields of Use
Polyurethane timing belts are used in all areas, from miniature drives, high-precision positioning and sorting mechanisms, small handheld machines to high-performance drives for building and woodworking machines.
Belts Characteristics
- High transmission power and long life
- Resistant to oil, fuel, benzol, UV radiation and ozone
- Wear-resistant
- Temperature range, depending on application, from −30 °C to +80 °C
- Maintenance-free
