•Analysis of partially textured slip bearing lubricated with couple stress fluids is presented.•Narrow groove theory (NGT) is incorporated in the derivation of analytical model.•Partially textured slip is effective for parallel bearing lubricated with couple stress fluids.
A theoretical model of partially textured slip slider and journal bearing lubricated with couple stress fluids is developed using narrow groove theory (NGT). The partially textured slip bearing configuration is analyzed using couple stress effects. The nondimensional pressure and shear stress expressions are derived based on one-dimensional analysis using modified Reynolds equation. The partially textured slip parameters used in the analysis are: nondimensional texture length; nondimensional depth of recess; land with slip to recess region ratio; and nondimensional slip coefficient. Partially textured slip is effective in the case of parallel slider and concentric journal bearing lubricated with couple stress fluids to yield an improvement in load capacity and reduction in coefficient of friction.
