Abstract—Flexure bearing is a new concept and used for precision applications such as Programmable Focusing Mechanism (PFM), linear compressor, etc. These bearings are compact and inexpensive. A flexure bearing is designed for specific applications. These designed can usually be done with the advanced design tool like Fine Element Analysis. With the advent of computers Fine Element Analysis has become the most suitable tool for the engineering analysis where the conventional approach is not suitable, geometric complexity are involved etc. This bearing contains three slots having 120° apart and 12 peripheral holes are used to clamp the disc rigidly onto a support structure. One central hole made for movement of shaft. The bearings are commonly made by Aluminum material we calculate the deformations in theoretical and FEA method by using Ansys Software. In this paper we are modeling the flexure bearing by using copper material we are calculate the deformations in theoretical and FEA method by using Ansys Software. We are analysis the deflection deformation on the both materials of bearing. We are analysis the deflection deformation on Flexure Bearing at different load (means 1 N to 5 N). Using software’s like CATIA and PROE, modeling of flexure bearing done. Also make Fine Element Method analysis on it by using Ansys software and lastly, this project considers the fatigue life criteria for flexure bearing and tries to optimize it. We are made design calculation and Fine Element Analysis for flexure bearing to make appropriate model and draw the performance charts for linear compressor bearing by comparing the power consumption with different temperatures, and capacity.
