Bearings

Marine bearings are essential internal engine components designed to support rotating shafts and reduce friction between moving engine parts. In marine engines, bearings are used throughout the engine assembly, including applications involving the crankshaft, connecting rods, camshaft, and other rotating components.

At U.S. Boating & Marine Supplies, shop marine bearings and internal engine components for a wide range of inboard, sterndrive, and marine engine applications. Whether you're rebuilding an engine, replacing worn components, or performing preventative maintenance, choosing the correct bearing for your specific engine is critical.

Marine Engine Bearings

Marine bearings may be available for applications such as:

  • Main Bearings – Support the engine crankshaft within the engine block.
  • Connecting Rod Bearings – Provide a bearing surface between connecting rods and the crankshaft journals.
  • Camshaft Bearings – Support the camshaft and help maintain proper camshaft operation.
  • Thrust Bearings & Washers – Help control crankshaft end play and axial movement.
  • Engine Bearing Sets – Replacement bearing sets for specific engine applications.

Choosing the Correct Marine Bearing

Bearing dimensions and specifications can vary significantly between engine models. Before ordering, verify the engine manufacturer, model, year, displacement, cylinder configuration, crankshaft specifications, bearing size, and OEM or manufacturer part number. For engine rebuilds, always inspect the crankshaft journals and related components and follow the engine manufacturer's specifications for bearing clearance and installation.
