In this work, a hybrid composite journal bearing (HCJB) composed of carbon/phenolic laminated composite bush and steel housing was designed for marine vessels because the composite journal bearing reduces the possibility of the seizure problem between the journal and bearing. The two components of bearing were assembled by interference fit joining method and a series of durability tests were conducted using the laboratory bench with the lubricants of SAE 30 oil, water, and sea water. That the HCJB was found reliable under the interference fitting loads and environmental temperature change. In order to address the effect of temperature on the reliability of the HCJB, the finite element analysis was performed with respect to environmental temperatures, from which it was found that the compressive stress in the hoop direction was largest (55.5 MPa) when the environment temperature was -30 deg C, which was much lower than the compressive strength of the composite (220 MPa) in the hoop direction.
