The HOT profile (Helical Offset Tooth) is a special profile for endless rubber timing belts used in low-noise drive systems. The arrow-shaped helical toothing combines the properties of the standard profile with integrated self-guiding, ensuring smooth running and precise power transmission even at high speeds.
CONTI® SILENTSYNC timing belts with HOT profile are made of synthetic rubber with a specially treated backing and a tensile-resistant aramid cord. This material combination enables high dimensional stability, low elongation, and consistent running characteristics. Additionally, the timing belts are conditionally resistant to oil, coolants, and ozone. The flexible belt backing allows for counter-bends.
Endless manufactured rubber timing belts with a HOT profile are particularly suitable for noise-sensitive machinery and automated systems. They are electrically conductive according to ISO 9563 and temperature-resistant from -40 °C to +95 °C.
