In order to maximize the application of ELATECH
®
timing belts,
construction with special cords is available on request:
• HPL high performance cords: the cord cross section is increa-
sed compared with standard. This results in a lower belt
elongation and more precise positioning accuracy.
• HFE high Flexibility cords: the cord cross section is spread on
a higher number of single filaments. This results in a lower
bending stress and therefore in a higher resistance at reverse
bending of the cords.
They allow using pulleys and idlers up to 30% smaller in dia-
meter compared to standard.
• INOX stainless steel cords are suitable for application in
aggressive environments. They have lower tensile strength
than standard cords.
• Aramid: increases belt flexibility and decreases belt weight.
It is to be noted that steel cords offer the best technical perfor-
mances and dimensional stability of the belts.
For application with special cords ask our engineering depart-
ment.
The timing belts manufactured by ELATECH
®
have been
desgned to comply to every need of the design engineer in linear
motion, power transmission and in conveying applications
where precise synchronisation is needed.
ELATECH® timing belts are manufactured with the body in
thermoplastic polyurethane with excellent wear resistance and
with high tensile strength steel cords. A special polyamide fabric
on the tooth (on request) reduces the coefficient of friction,
improves the tooth engagement and reduces noise.
