Fabric or truly endless cord
Extremultus flat belts from the polyester line are available to suit applications with two different types of tension members.
Flat belts with polyester fabric tension members can transmit high levels of pull at little elongation and are not sensitive to fluctuations in ambient conditions. They are also very good value.
Polyester fabric tension member:
Flat belts with truly endless polyester cord tension members can transmit high levels of pull, require only very short take-up ranges, can transmit high levels of specific effective pull at low elongation and are impact resilient.
Because they are very flexible and track very steadily and evenly, they are an excellent choice where high levels of power transmission and multiple rotations are required.
