Product Description

 
The four-point contact ball slewing bearing with external gears is widely used in various heavy-duty machinery and equipment due to its high load capacity, compact design, and high precision. Proper selection and maintenance are crucial to ensuring its long-term stable operation.                                                    
 

Basic Structure
Four-Point Contact: The rolling elements (steel balls) inside the bearing form four-point contact with the raceways of the inner and outer rings. This design enables the bearing to simultaneously withstand radial, axial, and overturning moment loads.
