Wärtsilä water lubricated composite bearings

Wärtsilä Envirosafe bearings are composite bearings, offering an environmentally friendly solution, specifically designed for stern tube applications.

Our range of water lubricated bearings offers excellent performance when compared to competing products and covers both commercial and military 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 and repair.

Wärtsilä also offers a Bearing wear down gauge system, which remotely indicates the wear of the stern tube or bracket bearing, by measuring the drop of the propeller shaft. This allows to receive information on the wear status of the sterntube bearings without diver assisted underwater wear down measurements. Based on the previously analysed data, the wear of the bearings can be predicted.
