We analysed a bearing with a secant shaped slider and with the stator having a porous facing backed by a solid wall, using a magnetic fluid lubricant flowing as per Jenkins model. Computed values of the bearing characteristics are displayed in tabular form. The load capacity, friction on the slider and the coefficient of friction decreased with increasing values of the slip parameter. The load capacity decreased and friction as well as the coefficient of friction increased with increasing values of the material parameter. However, the position of the centre of pressure did not significantly alter owing to the changes in slip parameter. But it slowly shifted towards the inlet when the material parameter increased.
