Section SPZ Wrapped Dunlop Red Fire V-Belts
Wrapped Wedge Belts are designated by letters standing for their cross-section, e.g. SPZ followed by a number e.g. 1600 which specifies the belts pitch length Lp in mm. Due to their high power ratings savings can be made over classical V-Belts, smaller pulley diameters and reduced numbers of belts and be incorporated into more compact drives. Wedge Belts are produced to BS3790, DIN 7753 and AFOR T 47-117 standards. They are manufactured in the cross-sections SPZ, SPA, SPB and SPC.
RED FIRE use different materials and design features, together with an improved production process, have led to the development of a new class of higher rated wrapped V-belts.
