Optibelt RED POWER II High Performance Wedge Belts

Construction

Optibelt Red Power II wedge belts.

The tension cord for all sections and cross sections consists of a special polyester cord. Due to the special treatment of the tension cord the Optibelt Red Power II wedge belt is very low stretch and service free, so that retensioning is not necessary.

The fibre mixture over and under the tension cord guarantees highly dynamic load of the belt and provides good flexibility in combination with the polyester tension cord.

The cover fabric is extremely wear resistant, flexible and abrasion proof.

RED POWER belts are readily avialble in SPZ, SPA, SPB and SPC sections
(click on section size to view detailed list of belt lengths).
