A base member has a face surface arranged to face a load receiving member. A plurality of grooves are provided in the face surface and bearing inserts are supported in these grooves. Such inserts project beyond the grooves and terminate in end bearing surfaces arranged to be engaged by the load receiving member. Lubrication inlets comprise cross grooves communicating with the insert receiving grooves whereby to supply lubrication under pressure to the area between the inserts. The system is associated with a high pressure source whereby oil is arranged to be forced over the end bearing surfaces of the inserts to provide a hydrostatic support for the loading receiving member. A water cooling passageway is provided in the base member.
