150103150024A004 Main gear Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

The Sany 150103150024A004 main gear is a core transmission component exclusive to Sany engineering equipment. It strictly follows the original manufacturer’s technical specifications and is precisely adapted to Sany gear pump series models. As the core component for power transmission in gear pumps, it meshes with the driven gear and plays a key role in efficiently transmitting power and regulating speed, ensuring lossless power transmission in the hydraulic system. It is suitable for complex working conditions such as mining, construction, and metallurgy, and can withstand high-frequency operation and heavy-load impact. It is the preferred original manufacturer part for B-end procurement and equipment maintenance.
This product addresses the pain points of ordinary main gears, such as large tooth profile deviation, easy wear, high transmission noise, and easy tooth breakage. It is made of high-quality alloy steel and precision machined through multiple processes such as quenching hardening, precision grinding, and dynamic balancing calibration. The tooth surface is smooth and the meshing is precise. It can be directly adapted to the corresponding machine model without modification, reducing operation and maintenance costs and meeting the core needs of “cost reduction and efficiency improvement, and stable transmission”.

Core technical parameters:
