SINOCONVE 4L Type Pentagonal V-Belts for General Machinery with Stable Power Transmission

4L Pentagonal V-Belt

4L is a pentagonal V-belt with a 0.50 inch top width, 0.31 inch thickness, and 40° belt angle. The product knowledge workbook confirms the section dimensions but does not provide a verified inside-length production range for this type. Inside length Li must therefore be confirmed from the required belt marking, sample, drawing, or pulley layout before production. The reinforced tensile structure and durable rubber body provide stable transmission, resistance to abrasion, heat, oil, and repeated flexing, and dependable service in packaging machinery, printing equipment, textile machines, electronic production equipment, glass machinery, and chemical processing equipment. Custom marking and OEM packaging are available.
