POLYURETHANE BELTS
Polyurethane Timing, Conveying and Indexing Belts
The E Steel cord tension member
Highly flexible tension inserts - the E Steel cord tension member
Other Belts
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.
Application information: For intended application under extreme
conditions please contact our Technical Department for advice.

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