Pinion

The pinion is forged from high-quality alloy steel as a single piece, undergoing tempering, carburizing, and precision grinding to achieve high strength, high wear resistance, and excellent transmission accuracy. The gear meshing is smooth, with low operating noise, and it can effectively withstand high torque loads. It features a compact structure, high machining precision, and can be customized to meet different equipment requirements. It is widely used in feed machinery, grain drying and storage, and organic compound fertilizer equipment to achieve power transmission and smooth operation, ensuring efficient and reliable operation of the entire machine.
