Rothe Erde 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 bearing unit. Their low profile and an excellent weight/performance ratio, open centre, and the possibility of an integrated gearing make Rothe Erde slewing bearings ideal structural components. Rothe Erde manufactures slewing bearings from 300 up to approx. 8,000 mm diameter as monobloc systems and segmental bearings up to 18,000 mm diameter.
