Slewing Bearing for Excavating Machine
The slewing bearing used by the excavator is a single-row ball slewing bearing, and the teeth are quenched. The main function is to support the upper cab and the mechanical arm and other mechanisms, and to control the rotation of the cab and the mechanical arm. The motor or reducer drives the pinion to rotate, and the pinion drives the slewing bearing to rotate, so that the upper mechanism connected to it rotates accordingly. The slewing bearing used in the excavator is required to carry a large axial force, overturning moment and gear circumferential force, and has higher requirements on the clearance, installation size and material of the slewing bearing.
About Excavator
Excavator, also known as excavation machinery, is an earth-moving machine that uses a bucket to excavate materials above or below the bearing surface and load it into a transport vehicle or unload it to a stockyard.
The materials excavated by the excavator are mainly soil, coal, silt, soil and rock after pre-loose. Judging from the development of construction machinery in recent years, the development of excavators is relatively fast, and excavators have become one of the most important construction machinery in engineering construction. The three most important parameters of an excavator: operating weight, engine power and bucket capacity.

Application of slewing bearing
The slewing bearing used by the excavator is a single-row ball slewing bearing, and the teeth are quenched. The main function is to support the upper cab and the mechanical arm and other mechanisms, and to control the rotation of the cab and the mechanical arm.
Application principle of slewing bearing
The motor or reducer drives the pinion to rotate, and the pinion drives the slewing bearing to rotate, so that the upper mechanism connected to it rotates accordingly.
Why use a slewing bearing？
The slewing bearing used in the excavator is required to carry a large axial force, overturning moment and gear circumferential force, and has higher requirements on the clearance, installation size and material of the slewing bearing.
Selecting a suitable slewing bearing can effectively improve the safety and stability of the equipment, and tooth quenching can improve the wear resistance of the teeth, thereby increasing the service life of the slewing bearing.
