A full journal bearing has a shaft diameter of 80.00 mm with a unilateral tolerance of –0.01 mm. The 1/d ratio is unity. The bushing has a bore diameter of 80.08 mm with a unilateral tolerance of 0.03 mm. The SAE 30 oil supply is in an axial-groove sump with a steady-state temperature of 60°C. The radial load is 3000 N. Estimate the average film temperature, the minimum film thickness, the heat loss rate, and the lubricant side-flow rate for the minimum clearance assembly, if the journal speed is 8 rev/s.
