This mounting is used when the engine / gearbox is mounted on soft pads, and there is no need for intermediate bearing between the rear bearing and coupling.
It comprises of a spacer tube, a water scoop outer bearing and an inboard flexible gland assembly. The bearing is lubricated by water supplied from the engine cooling system. This is injected into the sterntube through the inboard flexible gland.
The length of the tube is defined by the tightened measurment ‘S’ given by customer.
Depending on the application, a water inlet, usually connected to the engine cooling system can be set up on the tube close to the seal.
