Kta38-g5 Cummins Genset Cummins Spare Parts Crankshaft Pulley For K38/K50 3069778

The product adopts SAE 1045 cold rolled carbon steel forging, which is processed by carburising and quenching. As a result, the surface hardness reaches HRC 50-55, and the tensile strength is ≥ 850MPa. Compared with the common casting pulley, its wear resistance is improved by 70%, making it suitable for the high-speed working conditions of an engine at 1500r/min.

The wheel body undergoes a dynamic balancing test (with a residual unevenness ≤ 0.5g-mm). The design of six evenly distributed bolt holes reduces the centrifugal force of rotation. As a result, the vibration amplitude is reduced by 30%, which extends the life of the belt and bearings.

The temperature range is from -40°C to 200°C. After passing the salt spray test (in accordance with the ASTM B117 standard) for 1200 hours without corrosion, it is adaptable to high-humidity and high-salt spray environments such as mining and ocean engineering.

It can support a peak torque of 1800N-m. By being linked with the high-pressure fuel pump, water pump, and generator pulley of the KTA38-G5 generator set, it guarantees the stability of the 380V/50Hz power output.

The whole production process follows the Cummins CES 14650 global standard, has passed ISO 9001 and IATF 16949 dual certification, and the raw material batch test report can be traced back to the steel mill.

100% magnetic particle flaw detection ensures the absence of internal cracks. The depth of the high-frequency quenching layer on the gear surface is 1.2-1.5mm, and the tooth surface roughness is Ra≤0.8μm, reducing the meshing noise.

In terms of generator set power transmission, it is a core transmission component for the crankshaft power output of the KTA38-G5 diesel generator set. When matched with the Stamford generator (model S6L1D-E41), it can achieve a standby power output of 880kW.

For the power system of engineering machinery, it is suitable for the hydraulic pump drive system of excavators and mining trucks equipped with K38/K50 engines, and it can withstand the impact load of frequent starting and stopping.

In the marine auxiliary engine drive system, it is part of the crankshaft-belt pulley-sea water pump linkage system for marine generator sets, meeting the IP23 protection level and salt spray corrosion resistance requirements.
