Slewing bearings, also known as large slewing bearings, are designed to carry combined loads (axial, radial, and bending moments) in heavy equipment. These bearings are commonly used in rotating and articulated systems and are capable of carrying very high loads under severe operating conditions.
These types of bearings typically consist of one or more rows of balls or rollers housed within a large inner and outer ring, and in some models, they have internal or external teeth for engagement with power transmission systems.
