Abstract: The word 'bearing' comes from the verb 'to bear', a bearing is thus a machine element that permits one part to bear another, by allowing relative motion between them. A bearing is a machine element that constrains relative motion and reduces friction between moving parts to only the desired motion or it is a mechanical element which locates two machine parts relative to each other and permits a relative motion between them. Bearings are components that are used to reduce the amount of friction in a machine. The present work reported in this paper is specific to the selection of a bestgeometry among the selected geometries for flexure bearing used in linear compressor. This paper proposes FEM as tool to find the equivalent stress.Selection of geometry is one of the most important steps in the process of design. The best geometry is one which will serve the desired objective like performance and service life at minimum cost. The main objective of this paper is to investigate best geometry of flexure spring to enhance its performance and improve upon the life of the flexure of service. Performance of the flexure, service life of the spring can be enhanced by achieving lower operating stresses and higher factor of safety.
