BRECO®, BRECOFLEX® timing belts THE POWER OF A WELL-MESHED GROUP. BRECO is member of Mulco-Europe EWIV

Keeping things moving! Keeping things moving! Keeping things moving! Innovation is our drive - this principle marks BRECO Antriebstechnik Breher GmbH & Co., manufacturer of BRECO® and BRECOFLEX® timing belts as the most innovative producer in the eld of polyurethane timing belt technology worldwide. The basis for a high-quality and reliable product is provided by wear resistant polyurethane for the belt body and high tensile steel cord tension members. The name BRECO became the synonym for polyurethane timing belts resulting from years of experience in the eld of thermoplastic polyurethane,...

Timing belt types Timing belt types ATP high capacity prole ATP Further increased performance, noise reduction and extension of the belts useful life led to the development of the ATP timing belt. The basic concept of the ATP prole provides the division of the trapezoidal tooth into two individual and load bearing teeth. Performance increase up to 60 %, running noise reduced by up to 10 db(A) and an increased longevity by: • Tooth surface area increased by 70 % • Uniform load/tension distribution • Improved power dispersion • Reduced polygon effect • Small construction width • Optimised...

Available versions Available versions Standard version, single-sided Nylon tooth facing The standard version of the BRECO® and BRECOFLEX® timing belt is a combined construction of the two materials: wear resistant polyurethane and high tensile steel cord tension members. The standard version is universal applicable for all tasks in the drive and conveying technology. Ordering code: without The belt base corresponds the standard version. An additional nylon tooth facing causes a lower friction coefcient, lightens the tooth mesh in the pulley and reduces noise. Transport belts on bed plates...

The curved teeth timing belt BAT/BATK The curved teeth timing belt BAT/BATK The special characteristics • Increased tooth load resulting from the tooth curve • Clearly reduced running noise due to a time elongated tooth mesh • Higher power transmission precision and lower vibration tendency due to a reduced polygon effect • The BAT is self-guiding in the preferred running direction, no anges are required The BATK is self-guiding in both running directions due to the integrated guiding track making anges obsolete • Length constant belts due to the application of high tensile steel cord...

BRECOFLEX® manufacturing process BRECOFLEX® timing belts BRECOFLEX® timing belts BRECOFLEX: The BRECOFLEX® timing belt is manufactured in endless lengths without tension member interruption. The tension member is spirally coiled. BRECOFLEX® timing belts are universal applicable for all tasks in the drive technology up to 10000 min-1. Application areas Endless timing belts for power transmissions All drives designed for a high performance should preferably be produced as BRECOFLEX® timing belts with a full length steel cord tension member. They can be subjected to both permanent operation or...

BRECO® manufacturing process BRECO® timing belts BRECO® timing belts (BRECO M: Open length / BRECO V: Joined belts) BRECO M: The BRECO® timing belt is manufactured in open length. The tension members are always arranged with parallel edges. Open length is required e.g. in linear transmissions. All tension members assume part of the load. BRECO V: BRECO® timing belts are manufactured from open length material welded to endless belts. In the join area the half number of tension members assume part of the load. The use of endless joined BRECO® timing belts is preferred in the conveying...
