POLYURETHANE TIMING BELTS<br />
Strength and Flexibility<br />
The timing belt strength and spring rate is determined by the tension member construction and<br />
placement. <strong>BRE<strong>CO</strong>flex</strong> <strong>CO</strong>., L.L.C. utilizes an advanced tension member construction with many small<br />
diameter filaments to achieve a strong and flexible timing belt. Competitive designs are stiffer and are<br />
more prone to fatigue of the tension members, resulting in reduced service life.<br />
The tension member construction also greatly influences the tooth shear strength and the power that can<br />
be transmitted. The <strong>BRE<strong>CO</strong>flex</strong> <strong>CO</strong>., L.L.C. design allows the urethane to fully bond all strands within a<br />
tension member cord. Competitive designs only encapsulate the outer layer of the tension member,<br />
leaving voids at the inner section of the cord. Comparative bonding pull tests have shown that <strong>BRE<strong>CO</strong>flex</strong><br />
<strong>CO</strong>., L.L.C. timing belts achieve up to 40% higher bonding strength.<br />
