Pulleys for washing machines

Pulleys for washing machines, especially a plastic pulley for drum washing machines. The belt pulley is a plastic injection moulded part with a bearing sleeve inlaid in the pulley. The advantage of this product is that the plastic particle injection moulded product is simpler to produce, more efficient and cheaper than the metal cast product, especially the composite polypropylene has better performance, higher wear resistance and less deformation, thus making the concentricity and flatness of the injection moulded product less inaccurate. In addition, by changing the bearing sleeve, injection moulding can be used for different types of bearings, eliminating the need to open moulds for metal pulleys and saving a large amount of mould costs. In addition, the application of the ribbed structure of the bearing sleeve enables the torque of the pulley to be met and ensures the strength and fatigue resistance of the product.
