"RED POWER II" Belts

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.

Optibelt RED POWER II materials and construction

Properties

The high-quality components in connection with product manufacturing make the Optibelt Red Power II a service free V-belt. Production is continuously monitored using state-of-the-art static and dynamic testing devices.

Application with drives using idler pulleys is possible due to the special set-up of the Optibelt Red Power II.

Its properties:

  • service free
  • strong power rating
  • favourable cost
  • SetConstant
  • environmentally friendly

Optibelt Red Power II are oil-resistant, heat-resistant and dust protected as standard.

Using the electrically conductive Optibelt Red Power II requires testing the stipulated properties according to ISO 1813. With Optibelt's acceptance test certificate according to EN 10204 “3.1.B" thus proving its anti-static properties.

V-belt tensioning

For the initial fitting of Optibelt Red Power II the same calculation methods are used as for standard Optibelt V-belts. Once correctly tensioned Optibelt Red Power II V-belts need no retensioning.

Applications

Optibelt Red Power II wedge belts were especially developed for mechanical engineering. The fields of application are among others compressors, pumps, presses, fans and other heavy duty drives.

Standardisation / Dimensions

Optibelt Red Power II wedge belts with the sections SPZ, SPA, SPB, SPC are standardised according to DIN 7753 Part 1, ISO 4184 and RMA/MPTA.
