ATN-system Timing belt pulleys

Operational reliability for your conveyor drive

With its modular, interchangeable fastening elements and profile cams, the BRECO® ATN system provides the ideal foundation for flexible conveying applications. For this modular system to deliver its full performance, perfectly matched system components are essential. Through Mulco sales partners, you obtain original BRECO® ATN timing belt pulleys precision-manufactured for this demanding tooth profile. They guarantee backlash-free, positive-locking meshing between belt and pulley, ensuring maximum operational reliability and process security.

BRECO® ATN10 and BRECO® ATN20 timing belts generally run on standard AT timing belt pulleys. However, to ensure full operational reliability, selecting pulleys from the dedicated BRECO timing belt pulley programme is strongly recommended.

In addition to standard pitches, customers can source specialised variants from their Mulco sales partner, including BRECO® ATN 12.7 as well as the BRECO® ATN10K6 and BRECO® ATN 12.7K6 self-tracking pulleys.

Across all designs, high-precision tooth gap geometries and pitch consistency ensure optimal tooth engagement, reliably preventing belt tooth jump. Manufactured from high-grade, quality-controlled materials, BRECO® ATN timing belt pulleys ensure smooth running and effectively minimise mechanical wear on the tooth flanks.
