The journal bearing can be represented by a plain cylindrical sleeve (bushing) wrapped around the journal (shaft), but the bearing can adopt variety of forms. It consists of two main components. The shaft in the middle is the journal and the part enveloping the shaft is the bearing, which is also known as the bush. The housing or the sleeve is to support the journal bearing structure. In current study, journal bearing test rig was developed to study oil behaviour characteristics. The benefits of test rig such as applicability to multiple or repetitive tests, wide range of operation, possibility of performing extreme value tests safely, possibility of using accurately adjusted bearing loads, possibility of studying different variables separately and possibility of performing demanding measurements is the key factors of test rig selection.
