Arrow-Shaped SILENTSYNC/EAGLE Polyurethane Open-Ended Timing Belts
SILENTSYNC/EAGLE (Arrow-Shaped) polyurethane timing belts in SILENTSYNC/EAGLE profile.
They are manufactured with the teeth and bottom from thermoplastic polyurethane with excellent wear resistance and with high tensile strength steel tension member, in special cases with kevlar or stainless steel tension member. The open-ended belts can be welded into endless belts.

Belts Construction

- Polyurethane arrow-shaped teeth
- Steel tension member
- Polyurethane back
- Nylon covering fabric on the teeth
Belts Fields of Use
SILENTSYNC polyurethane timing belts are used in special applications where a self-guiding belt that is not guided in the guide line or by pulley flanges is required. At the same time, these belts have significantly lower noise and vibration than other profiles with straight-cut teeth.
Belts are used in high-precision positioning and sorting applications, single-purpose machines, woodworking, packaging and food processing machines.
Belts Characteristics
- High transmission power and durability
- Temperature range, depending on application, from -30 °C to +130 °C
- Antistatic in accordance with ISO 9563
- Very low-noise
- Extremely low vibration
- Resistant to aging and ozone
- Maintenance-free
- Conditionally resistant to oil

Optional Belt Surface Layers
The choice of the surface layer depends on the type of machine, the ambient temperature, the size of the pulleys, etc. Specifying the surface layer is determined by the material and the thickness of the layer.
