SINOCONVE HAA Type Double V-Belts for Compact Serpentine Drives with High Flexibility

HAA Double V-Belt

HAA is a double V-belt, also called a hexagonal V-belt, with a 13 mm top width, 10 mm height, and 40° belt angle. The confirmed inside-length range is 61-197 inches (1549-5004 mm), and Li = La - 63 mm. The symmetrical profile provides working sidewalls on both sides, enabling reverse bending and power transmission through complex multi-pulley layouts. High-strength cords support equal power distribution and controlled elongation, while the rubber body and outside fabric provide resistance to heat, oil, ozone, abrasion, and flex fatigue. It is suitable for spinning machinery, compact blending systems, HVAC equipment, fans, pumps, and lawn and garden machinery.

Technical Data

Product Advantages

• Compact HAA hexagonal profile supports flexible serpentine routing
• Two active side surfaces transmit power through inner and outer pulley paths
• High flexibility improves repeated reverse-bending performance
• Reinforced tensile member supports balanced power distribution and low stretch
• Suitable for spinning machinery, HVAC systems, pumps, fans, and garden equipment

Structure

The belt contains top rubber, a high-strength reinforcement layer, buffer rubber, bottom rubber, and protective outside fabric. The symmetrical section creates driving sidewalls on both sides.

Model Naming Rule

Model = section + inside length Li in inches. Example: HAA 61.
