The thinner the single wire, the more flexible the overall tension member! This interrelation led BRECO® to develop BRECO® and BRECOFLEX® timing belts with E tension members. In the E tension member the cord cross-section is distributed to a greater number of thinner individual wires and, therefore, the bending fatigues are markedly lower. The major advantage of the E tension members is higher flexibility. This is especially important, when smaller mounting dimensions for pulleys and tension rollers are required. The minimum number of teeth and/or minimum diameter of the pulleys can be up to 30% less, compared with standard tension members. Timing belts with E tension members are recommended for multi-shaft drives with frequent bends.

Summary

• Thinner individual wires in the Steel cord
• Higher dynamic capabilities
• Extremely high bonding and bending fatigue strength
• Smaller pulley and tension roller diameter
• No correction of the synchronising pulleys are necessary
