Application of slewing bearings in ships and marine equipment

Slewing bearings are key components for realizing relative rotational motion in marine and oceanographic equipment. They can withstand axial, radial loads, and overturning moments, with a wide range of applications, mainly including the following categories:

Marine Vessels：

• Deck machinery: Such as cargo winches and cranes. Slewing bearings enable 360° rotation of the boom, facilitating cargo loading/unloading and position adjustment.

• Ship steering systems: In the steering gear structure of some special-purpose ships, slewing bearings assist the flexible rotation of the rudder blade to ensure precise steering of the ship.

• Helicopter decks: Rotatable helicopter decks rely on slewing bearings for angle adjustment, adapting to different wind directions and helicopter takeoff/landing requirements.

Ocean Engineering Equipment：

• Offshore platforms: In the rotating structures of jack-up or semi-submersible platforms (such as drilling turntables and platform cranes), slewing bearings support the rotating parts, ensuring the stable operation of drilling and hoisting operations.

• Floating Production Storage and Offloading (FPSO) units: Their mooring systems, rotary joints, and other components often require slewing bearings to adapt to the shaking and rotation needs in the marine environment.

• Underwater robotic equipment: Slewing bearings are used in the rotating joints of some underwater operation machinery to ensure flexible rotation in the high-pressure underwater environment.
