In construction machinery and heavy vehicle manufacturing, trailer slewing bearings are an indispensable component. It is usually used to realize the vehicle trailer steering function, so that the vehicle can maintain good performance and stability under working conditions. Usually with double outer flange turntable structure, the manufacturing material requirements of the bearing are also strict.

The raw materials of trailer slewing bearings usually involve two types: casting and forging. Castings are favored by some manufacturers because of their lower cost. The low price does provide manufacturers with advantages in terms of cost control, but the disadvantages of this material lie in its mechanical performance strength and material tissue uniformity, which may affect the reliability and life of parts under high loads and long-term use. On the other hand, forged materials, although their raw material costs are higher, provide better quality and durability. During the forging process, the metal is shaped under very high pressure. This method can effectively improve the crystal structure of the metal and increase its overall strength and toughness. Forged parts are therefore more resistant to wear, fatigue and stress concentration in extreme environments, greatly improving product reliability and safety.
