Vbelt tensioning For the initial installation of optibelt RED POWER 3 Vbelts, the same methods are used as for standard Optibelt Vbelts. The tension values are to be calculated on the same basis or to be taken from the table on page 147. Once correctly tensioned optibelt RED POWER 3 Vbelts need no retensioning. Appliion areas

the suggested maximum belt speed for different can size exists, the 500 RPM rating for CEMA idlers translate into the following belt speeds: If these suggested maximums are exceeded, then a decreased life of the idler bearing will be experienced. To overcome this may require a decreased rating, or an increase in CEMA class.

T = belt tension (/ the total tension given in Tables ) R = outside radius of pulley rim W = belt width We applied the belt load over a shorter area than the typical belt load due to meshing considerations (see Figure !). This causes the belt force to be applied over a smaller surface area, thus the pressure loading is a little on the high side.

To minimize side travel on steel cord belt rolls, it is recommended that rolls be strung onto the conveyor in the exact sequence they were manufactured. Tensioning Once the belt has been pulled onto the conveyor system, it must be tensioned prior to splicing to facilitate correct positioning of the takeup and to eliminate sag.
