Crane slewing bearings are an essential component of cranes, connecting the upper slewing platform with the lower chassis and allowing the upper structure to rotate 360 degrees relative to the base. Slewing bearings play a crucial role in crane stability and safety, as they bear and transmit various forces from the load and structure, including axial, radial, and overturning moments.

Structure and Function of Crane Slewing Bearings

    A slewing bearing consists of an inner ring, an outer ring, rolling elements (usually rollers or steel balls), and a cage. Some designs also feature gears (internal or external) that engage with the drive mechanism to enable rotation. The rolling elements between the inner and outer rings ensure that the upper part of the crane can rotate smoothly relative to the chassis. Different types of slewing bearings (such as ball and roller types) are suitable for different loads and application environments, depending on the crane type and operational requirements.
