BRECOflex CO., L.L.C. offers three types of timing belt construction, each for a different kind of application. Knowing what these three types are and how to identify them is the first step in specifying a belt for a new design or for placing a reorder on a replacement belt
Timing Belt Construction Types
Each type is specified by a letter code.
Open-ended timing belts have a high spring rate and excellent tooth shear strength. If you are looking for a linear drive with stiffness and high repeatability, we recommend steel tension members over aramid fiber. The stiffest and strongest “M” belt would be the move-series AT10 or AT15.
Code M timing belts are available in 50m rolls or cut to length as per specification.
Spliced and welded timing belts are used in many general purpose applications. They are the preferred construction type for conveying, as well as for welded profiles and backings. We are able to machine these belts and they are available in most tooth configurations.
Truly endless code BFX polyurethane timing belts are extruded without a weld. This gives you the strongest belt construction type making it ideal for power transmission applications. They have steel tension members as a standard and are available in multiple material versions. The most popular tooth configuration is AT for more tooth shear strength. Double-sided BFX timing belts are also available for drive systems that change shaft direction. Custom lengths are available.
