Abstract Journal Bearing is used to bear the load and confine the rotation of the shaft. A loaded rotating journal (Shaft) is supported by a circular bushing (sleeve or bearing), the diameter of the bearing is slightly more than the diameter of the journal, to provide clearance so a proper supply of lubrication oil is possible, which can enhance the performance characteristics of journal bearing.
Journal bearing are mostly used to carry the radial loads of shafts working in dry and lubrication conditions. Journal bearing is used in various applications like sugar mill bearing, cement industry and turbine etc. Journal bearings may prematurely fail because of misalignment, irregular surface, lack of lubrication, contamination, etc., which impacts the industry's production costs are also hazardous for human life. When a bearing is used under diverse oil conditions, the temperature of the bearing has been seen increase in the industry. Because of this, the theoretical analysis of plain and texture (diamond shape) brass, bronze, and gun metal journal bearings lubricated with SAE-40 oil has been done in present study using ansys CFD. The inner diameter of the bearing has been subjected to internal knurling. In terms of temperature rise, the outcomes
of two bearings are compared. Performance of the textured bearing has improved in comparison to the plain bearing.
