To overcome the spring back behavior of the flexural pivots, a novel statically balanced flexural pivot with two symmetrically arranged pre-compressing springs (SBFP-2PCS) is proposed. Five balancing design parameters and two design objectives of the SBFP-2PCS are specified. The design parameters are determined based on the stiffness analysis of the SBFP-2PCS. Samples of the SBFP-2PCS are built to verify the proposed balancing method. The test result of the average stiffness reduction is 92.5%. The proposed method is general for various flexural pivots with low axis drift.
