The tooth profile of timing belts is based on the AT tooth profile, but the teeth are crowned. The timing belt is thus guided and self-centred, which eliminates flanges on the pulleys and eliminates lateral drift of the timing belt. The timing belt with an arched BAT profile reduces noise. The meshing of the timing belt is optimised.

Caution: it requires a perfect alignment of the pulleys and turns only in one direction. (For two directions of rotation, use BATK provided with a guide).

ADVANTAGES

> Self-steering: flangeless pulleys

> Very low noise level: less vibration when meshing

> Very weak polygonal effect

> Vibrations are suppressed when using support rollers or idlers on the tooth side (no minimum angle of wrap).
