Abstract
Since the past years, rubber bearing has been adopted for various such as ferry boat, fishing boat, navy vessel, etc. as a water lubricated strut bearing and stern tube bearing. However, there was restriction of a certain degree in application of the said bearing due to mainly costwise matter, i.e. the same is much expensive compared with conventional bearing of lignumvitae.
Recently, the demands for water lubricated rubber bearing is ever-increasing in place of white metal bearing taking prevention of the oil pollution into consideration.
In keeping with the above trend, an investigation on wear down and condition of the bearing contact for the rubber bearing has been made, leading to the following summeries:
(1) Wear down of rubber bearing is approximately 0.4-0.5 mm per year.
(2) The contact seems to be good enough for service, and whose condition proves to be almost the same as that of white metal bearing being slope bored.
