Marine Flanged Slewing Bearing

About product

The marine flanged slewing bearing is a specialized type of four-point contact ball slewing bearing designed for a wide range of applications. This particular slewing bearing variant does not possess teeth, and both the inner and outer rings are flanged. It falls under the light series of slewing bearings.

With its robust construction and precise engineering, the marine flanged slewing bearing delivers reliable performance and durability in harsh marine conditions. It is engineered to withstand the challenges posed by factors such as corrosion, saltwater exposure, and harsh weather conditions commonly encountered in maritime environments.

Product Detail

The distinctive feature of the marine flanged slewing bearing is the presence of flanges on the outer ring. These flanges simplify axial positioning, making it easier to align and secure the bearing in place.

The Suitable Environment Of  Marine Flanged Slewing Bearing

Marine flanged slewing bearings are designed and built to withstand the demanding conditions found in marine environments. They are well-suited for the following environments:

  • Offshore Applications: Marine flanged slewing bearings are commonly used in offshore platforms, including oil rigs, drilling platforms, and production facilities. These bearings can withstand the harsh conditions associated with offshore operations, such as saltwater exposure, high winds, and corrosive elements.
  • Shipbuilding: Marine flanged slewing bearings are utilized in various shipbuilding applications. They can be found in ship cranes, davits, winches, and other deck machinery. These bearings offer reliable performance in marine environments, including exposure to seawater, vibrations, and heavy loads.
  • Coastal and Harbor Equipment: Slewing bearings with flanges are employed in coastal and harbor equipment, including dock cranes, port machinery, and material handling systems. These bearings are designed to handle the challenges posed by coastal environments, such as saltwater corrosion, abrasive particles, and continuous operation.
  • Offshore Wind Farms: Marine flanged slewing bearings play a crucial role in offshore wind turbines. They are used in the yaw and pitch systems, enabling the proper orientation and adjustment of the turbine blades. These bearings are exposed to marine conditions, including wind, saltwater, and temperature variations.
  • Marine Construction: Marine flanged slewing bearings are employed in various marine construction applications, such as pile driving equipment, marine cranes, and dredging machinery. These bearings are designed to withstand the rigorous conditions encountered during marine construction projects, including heavy loads, vibrations, and exposure to water.
