The manufacturing process of bearing sleeves includes casting, forging, machining, and heat treatment. Different processes have different impacts on the performance and cost of bearing sleeves:
1. Casting: Casting is suitable for bearing sleeves with complex shapes and has a lower cost, but castings may have defects such as porosity or shrinkage, affecting strength.
2. Forging: Forging can improve the density and mechanical properties of materials and is suitable for high-load conditions, but the cost is higher.
3. Machining: Machining is a key process to ensure the dimensional accuracy of bearing sleeves, including turning, milling, and grinding. Machining accuracy directly affects the fit quality and performance of the bearing sleeve.
4. Heat Treatment: Heat treatment can improve the hardness and wear resistance of materials. Common heat treatment processes include quenching, tempering, and surface carburizing.
