The applicationareas include compressors, pumps, presses, fans and otherheavy duty drives.standardisation/Dimensionsoptibelt rED POWEr 3 wedge belts in the profiles SPz, SPA,SPB, SPC, 3V/9n, 5V/15n and 8V/25n are standardisedaccording to DIn 7753 Part 1, ISO 4184 and rmA/mPTA.Abrasion resistantcover fabricThe tension cord consists of a special polyester cord. Due tothe special processing of the tension cord the optibelt rEDPOWEr 3 wedge belt is very low-stretch and maintenancefree, so that re-tensioning is not necessary.The transverse fibre mixture on top of and under the tensioncord guarantees a high dynamic load of the belt andensures great flexibility. The cover fabric is highly flexibleand abrasion-proof.PropertiesThe optibelt rED POWEr 3 is maintenance-free due to thehigh quality components and the special production method.The production processes are continuously monitored usingstate-of-the-art static and dynamic testing devices. Theoptibelt rED POWEr 3 is suitable for the application indrives with idler pulleys due to its special construction.The rED POWEr 3 has the following properties: maintenance-free Powerful Cost-effective S C plus usable in sets Environmentally friendly Electrically conductive according to ISO 1813 Oil-resistant Heat-resistant Dust-protected as standardOn request with acceptance test certificate according toEn 1020 “3.1.B“.V-Belt tensioningFor the initial installation of optibelt rED POWEr 3 V-belts,the same methods are used as for standard OPTIBELTV-belts. The tension values are to be calculated on the samebasis or to be taken from the table on page 138. Oncecorrectly tensioned optibelt rED POWEr 3 V-belts need nore-tensioning.Table 1ProfilesPZsPasPBsPcBelt top widthbo 9.712.7 16.322Datum widthbd 8.5111419Belt heighth 8101318recommended minimumdd min6390140 224datum pulley diameterWeight per meter 0.074 0.123 0.195 0.377(kg/m)Flex rate (s-1)fB max 100Belt speed (m/s)vmax 55**v 55 m/s.

PrODucT DescriPTiOnoptibelt Blue POWer high PerFOrMance WeDge BelTsstructure/Propertiesoptibelt BLuE POWEr wedge belts:Transverse fibremixture made t BLuE POWEr wedge belts in the profiles SPz, SPA,SPB, SPC, 3V/9n, 5V/15n and 8V/25n are standardisedaccording to DIn 7753 Part 1, ISO 4184 and rmA/mPTA.Aramid tension cord/maintenance-freeCore with transverselyalignedfibre layerAbrasion-resistantcover fabricThe aramid tension cord has extremely low-stretch comparedto common materials such as polyester. The breakingstrength is almost twice as high with the same cord diameter. nevertheless, the fibre is extremely flexible. The highquality specially prepared aramid tension cord is embeddedin a rubber compound. It is supported by the top andbottom structures. These consist of a polychloroprene rubbercompound with tranverse fibres. The abrasion-proof coverfabric is coated with a special rubber compound and coversthe whole belt. The V-belt is electrically conductive according to ISO 1813optibelt BLuE POWEr belts are mainly used when highest power transmission levels are required there are limited design dimensions there is only little installation and tensioning space high temperature influences occurThis way, a much better performance is guaranteed e. g.with the same number of belts. Even the operation of oncecritical drives is now largely free of risk. Higher load limitsare now safety zones. Thus optibelt BLuE POWEr belts aremainly implemented in heavily loaded drives:Table 3ProfilesPBsPcBelt top widthbo 16.322Datum widthbd 1419Belt heighth 1318Distancehd 3.54.81802800.2060.389recommended minimumdd mindatum pulley diameterWeight per meter (kg/m) Flex rate (s-1)fB max 100Belt speed (m/s)vmax 50**v 50 m/s.
