Marine bearing industry and port authorities need continuous “uptime” as they exist in a 24/7 working environment, be it drive shafts, overhead cranes or forklifts.
Marine Spares bearing Special solutions: The first is the use of split roller bearings, which allow for quick bearing changes, especially in difficult to access locations, such as drive shafts. For pulleys, cranes and tensioner blocks we recommend the use of SL pulley bearings.
These marine bearings provide additional high dynamic and static load ratings and are fitted with rubber seals to prevent water and dirt ingress. To prevent the unloading process from slowing down, we can supply leaf chain forklift chains cut to length within 24 hours. Our global freight relationships enable us to serve markets around the world, so that our bearings can meet ships in port if necessary.

Marine bearing of Industry common
There are 5 main types of bearings for marine propulsion engines – Marine Bearings
Process release bearings
Process split bearings offer the benefits of conventional bearings with the added feature of easy assembly around the shaft. The entire assembly is split into two halves to simplify the installation, inspection and replacement of the shaft table bearings, which can be done without disassembling or damaging other components of the system.
Opposed outer spherical bearings
This eliminates the need to dismantle gears or couplings, dismantle drives and dismantle shaft systems. They are an alternative to standard spherical roller bearings.
Some other additional bearings include
Bearings containing leaded bronze
Leaded bronze bearings have two main layers beneath a flexure plate layer that protects the bearing from corrosion and dirt when not in use. Once the bearing is in use, the layer flashes to reveal a nickel layer that prevents tin and other elements from corroding the metal of the bearing. The next layer is made of lead bronze, which provides good wear resistance. A steel backing provides structural support for the entire bearing.
Bimetallic bearings consist of two main layers. The first layer is the main component, aluminium-tin, followed by an aluminium bonding layer. This layer is combined with a steel backing to provide support and shape.
Primarily found in two-stroke propulsion engines, trimetallic bearings have three main layers. Below the flash layer is the cover layer, which is made of a white metal such as tin-antimony-copper and is used to protect the bearing from flash during storage and operation.
Next is the interlayer, which acts as a corrosion-resistant barrier to the cover layer. Finally, the inner lining provides a layer between the interlayer and the steel backing support.
