POPULAR BEARING TYPES IN THE METALS INDUSTRY STEELMAKING STEELMAKING The main support positions for the ladle furnace present a challenging application for bearings. They experience very high loads and misalignment at very low speeds. In addition, cyclic and reversing rotation occurs. The Timken solution uses solid or split high-performance spherical roller bearings mounted in custom-designed housings. The float position housing incorporates cylindrical roller ladder bearings to accommodate the significant thermal axial growth of the furnace assembly. SPHERICAL ROLLER BEARINGS LADDER BEARINGS...
