SINOCONVE SPZ Type Narrow V-Belts for Small Pulley Drives with Low Bending Resistance

SPZ Wrapped Narrow V-Belt

SPZ is a wrapped narrow V-belt with a 9.7 mm top width, 8.5 mm pitch width, 8 mm height, and 40° belt angle. The product knowledge workbook gives a Lw marking range of 20-210 inches (508-5334 mm). For the website, the selectable models are organized by full-inch inside length Li from 19 to 208 inches. Its reinforced tensile structure and wrapped rubber body provide low bending resistance, stable metric pulley engagement, and efficient compact transmission. The belt also offers good resistance to heat, oil, abrasion, ozone, and repeated flexing. It is suitable for compact fans, pumps, machine tools, light compressors, generators, and metric industrial machinery. Custom marking, matched sets, and OEM packaging are available.
