Dunlop SPA section wrapped wedge belts 13mm top width, 10mm thickness
Wrapped Wedge Belts are designated by letters standing for their crosssection, e.g. SPA 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 in a range of over 400 lengths.
Dunlop V-belts have specially treated jackets to give superior anti-static, heat and oil-resistant properties and are static conductive to ISO1813.
