4440813 Original Excavator Fan Belt for ZX120

The original fan belt part number 4440813 is a transmission and cooling component provided by Hitachi Construction Machinery for the ZX120 series hydraulic excavator (with a total working weight of approximately 12 tons and an engine model of Isuzu 4BG1T). This belt is mainly used to drive fans, generators, and water pumps to ensure the normal operation of the engine cooling system. Its universal models usually cover ZX120/130H equivalent series models, as well as similar tonnage excavators such as ZX200 equipped with 4BG1 and 6BG1 engines. As the original transmission belt, it matches the depth of the pulley groove and is strictly prohibited to use non-standard spare parts to ensure transmission efficiency and system reliability.

This product is an original V-shaped V-belt, usually made of a composite material of chloroprene rubber and polyester rope. Typical technical parameters: the section model is type A or type B (top width 13 – 17mm, height 8 – 11mm), the effective length is about 800 – 1000mm, the operating temperature range is -30 ℃ to+100 ℃, and the tensile strength is ≥ 1500N. The belt has anti slip tooth lines on the surface, and the interior is of cord layer or cord core structure, with oil resistance, heat resistance, and aging resistance. This belt complies with standards such as GB/T 1171 and ISO 4184, and can withstand speeds of ≥ 6000rpm and moderate impact loads, with a transmission efficiency of over 95%.
