Excavator turntable bearings are also commonly referred to as:
Slewing bearings
Slewing ring bearings
Swing bearings
Turntable bearings
The primary function of excavator turntable bearings is to enable the rotation or swing movement of the upper structure of the excavator, including the cab, boom, arm, and bucket.
This allows the excavator to maneuver and reach various positions without repositioning the entire machine.
Excavator turntable bearings are large, robust bearings designed to withstand heavy loads and dynamic forces associated with the swinging motion.
They typically consist of an inner ring, an outer ring, rolling elements (such as balls or rollers), and a cage that holds the rolling elements in place.
Regular maintenance and lubrication are essential for the optimal performance and longevity of excavator turntable bearings.
Proper lubrication helps reduce friction, heat, and wear on the bearing components.
Abnormal noise from the turntable bearing can be caused by issues such as uneven mounting, foreign objects, improper lubrication, or wear and tear.
Addressing these issues through proper maintenance, cleaning, and replacement can help resolve the problem.
Excavator turntable bearings are not only used in excavators but also in various other types of heavy machinery, including cranes, wind turbines, and industrial turntables.
Overall, the excavator turntable bearing is a critical component that enables the smooth and efficient operation of excavators and other heavy machinery by facilitating their rotation and maneuvering capabilities.
With over 1000 types of swing bearings available, we provide unparalleled choice and flexibility.Whether you're in the market for CAT, KOMATSU, HITACHI, HYUNDAI, KOBELCO, VOLVO, DOOSAN, JCB, CASE, LIEBHERR, LIUGONG, SANY, YUCHAI, XCMG, SUMITOMO, or any other leading brand, we've got you covered.
