A rail system for large turret bearing includes a turret bearing support structure, a rail support ring provided with a L-shaped cross section including an inward directed wedge mating face, at least two rings of radially elongated segment bolt holes, and an outermost ring of wedge bolt holes, a plurality of rail segments together forming a complete circle with an outer radius slightly smaller than the radius of the wedge mating face of the rail support ring. Each segment includes a sloped outer wedge mating surface, a downward facing contact surface with threaded bolt holes corresponding to the bolt holes in the rail support ring, an upper largely horizontal surface, and an inner largely vertical surface. The rail system includes trapeze shaped wedges each with at least one bolt hole and corresponding bolt(s), adapted to be tightened down between the wedge mating face of the support ring and the sloped outer wedge mating surface of the segments, and rail bolts for fastening the rail segments. A method for mounting the rail system and a method for replacing a rail segment are also disclosed.
