Rotek is the North American manufacturing leader of slewing bearings.Rotek slewing bearings are machine elements which absorb all axial and radial forces and the resulting tilting moments in a single self-retaining and ready-to-install unit.
Their low profile and an excellent weight/performance ratio, open center, and the possibility of an integrated gearing make Rotek slewing bearings ideal structural components.Rotek manufactures slewing bearings from 12 inches to 50 feet as non-segmented and segmental slewing bearings.Rotek slewing bearings are manufactured in the U.S.A.
