The Bare Metal ZLYJ Heavy Duty Reducer is a professional grade transmission unit characterized by its raw metal housing finish and reinforced structural design, engineered for ultra high torque industrial applications. Its core gear components are crafted from premium nickel chromium molybdenum alloy steel, undergoing a full cycle of precision forging and heat treatment that includes carburizing quenching and low temperature tempering. This process ensures the gear surface reaches a hardness of HRC 60 to 62 while maintaining core toughness, making it resistant to pitting deformation and fatigue fracture under prolonged heavy load conditions. The reducer features a massive cast steel housing with an uncoated bare metal finish, designed to maximize heat dissipation efficiency and provide a robust foundation for extreme torsional forces. The housing incorporates a vertical hydraulic cylinder assembly mounted on the side, which is integrated with the internal transmission system…
