![]() The thyssenkrupp Bearings group specializes in the production of slewing bearings and seamless rolled rings used in a wide-range of industries. This makes us part of a corporation with more than 150,000 employees all over the world. Specifically, it is associated with the “Bearings” area. Thyssenkrupp rothe erde® is part of the “Components Technology” Division of the global thyssenkrupp corporation. Modern production and testing devices allow production of bearing rollers with high accuracy. This investment was mainly focused upon the area of turning, grinding, sorting and inspection of bearing rollers. In recent years, psl® invested significant financial means into extending production capacity as well as in upgrading the technology for production of bearing rollers. For rotating tables with machine tools requiring a high degree of accuracy, psl® developed a line of precise crossed tapered roller bearings. The product range includes thrust ball, tapered and cylindrical roller bearings. The product range is continuously expanding depending upon the requirements of the market. Producing a wide range of tapered, cylindrical and spherical roller bearings, single-row, double-row and multi-row, of an inner diameter from 120mm in tapered bearings to an outer diameter of 2200mm. The dimensional range of psl® rolling bearings exceeds 2 meters in outer diameter. PSL ULTIMATE Class bearings bring enhanced performance with improved higher load carrying capacity or enable down-sizing of a design. Over the years, psl® rolling bearings have proved their perfection and great performance capabilities not only in highly demanding applications in heavy industrial applications, wind turbines, dumpers and railway vehicles but also in ultra-precision machine tool applications. We manufacture excellence in customized bearing solutions. Heat treatment: annealed, normalized, hardened and temperedĪs a single-source forging and machining provider, we pride ourselves in supplying high-precision, customized rings to a diverse range of industries.Our production capabilities mean we can manufacture to meet a wide range of customer needs, including: All manufacturing operations are located in our Aurora, OH facility. Rotek manufactures rothe erde® rings, with diameters ranging from 20 to 160 inches and unit weights from 145 to 9,000 pounds. A ring of this type can easily weigh as much as 30 tons. They play a key role in slewing bearings, large gear units, large valves, production facilities, sprocket wheels, wind turbines, and pipeline construction and can be up to 160” in diameter, seamlessly rolled. Rothe erde® rings are important components in a wide range of applications.
