Further development of the AT-profile resulted in the BAT-profile timing belts with reduced running noise. Apart from reduced running noise, this profile also boasts a larger tooth flank and is self-tracking in the preferred running direction. This polyurethane timing belt is primarily used where there are specific requirements relating to running noise and transmission accuracy.

BRECO® V-belts, in welded open lengths, can be joined to produce timing belts of any length, with half of the tension members assuming part of the load in the join area. Continuously welded BRECO® timing belts are preferred in conveyor systems to handle narrower installation widths.
