A bearing having flexure members for supporting an instrument and providing for limited rotation thereof. A plurality of spring members are arranged for exerting moments on the instrument the sum of which provides an anti-restraining moment to oppose a restraining moment exerted thereon by the flexure members. Each spring member includes means for adjusting the spring force exerted thereby to make the restraining and anti-restraining moments substantially equal even at zero rotation.
