The E tension member

The E tension member

In the E tension member the tension member cross-section is distributed to a lot more thin individual wires and, therefore, the bending fatigues are markedly lower in the individual wires. The advantage of the E tension members is a 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 fallen below up to 30% compared with standard tension members.
Timing belts with E tension members are recommended for multi-shaft drive 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

Steel cord tension members encapsulated in polyurethane:

The thinner the individual wire the more flexible the whole timing belt
