Water lubricated bearings
Provide ship operators with longer bearing life.
Our range of water lubricated bearings provide ship operators with longer bearing life through improved hydrodynamic operation, low coefficient of friction and wear rates, and reduced wear in abrasive and brown water applications. A variety of different supply options is available to suit specific applications including non-split bearings, split shells, or fully split housing that allows in-situ replacement or repair.

The restrictor has been designed to ensure that compartments traversed by the propulsion shaft are not compromised in the event of flooding, thus maintaining the vessel's compartment integrity during static or dynamic operation to get the vessel to shore. Through its automatic operation and acceptance of large angular and radial shaft movement, the restrictor ensures safe and reliable vessel operations. It can be fit with the shaft in situ on either side of the bulkhead.

The bearings have two faces of tilting pads on pivots, and transmit thrust from the shaft to the bearing housing minimising the tilting effect, and reducing stress levels. The oil circulating and cooling system is available either as a self-lubricating system with integrated cooler or as an external pump and cooler unit. Fitted with complete remote monitoring of the temperatures and oil flow, the thrust bearing solution enables easy management of the product.
