Rotek and rothe erde® slewing bearings and rolled rings are known world-wide for quality and dependability. In North America, the Rotek brand has a 55+ year history of quality, dependability and engineering excellence. That rich history and expertise isn’t going anywhere. Rotek will continue to provide the very same quality and excellence we’ve always provided. The only change is that now our slewing bearings and rolled rings will now be available under the rothe erde®brand.
Our rolled rings are used in the manufacturing of our world-class slewing bearings. These same rings are available commercially to you to meet your rolled ring forging needs.
rothe erde® rings are important components in a wide range of applications. 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. A ring of this type can easily weigh as much as 30 tons.
Rotek manufactures rothe erde® rings, with diameters ranging from 20 to 160 inches and unit weights from 145 to 9,000 pounds. All manufacturing operations are located in our Aurora, OH facility.
Our production capabilities mean we can manufacture to meet a wide range of customer needs, including:
• Structural steels, heat-treated steels • High alloyed steels • Non-ferrous metals (aluminum, copper) • Rectangular and profiled • Heat treatment: annealed, normalized, hardened and tempered • Special treatments • As-rolled and machined
As a single-source forging and machining provider, we pride ourselves in supplying high-precision, customized rings to a diverse range of industries.
Globally, no one knows more about slewing bearings.
As key design and connecting components, rothe erde® slewing bearings prove their value each and every day in applications such as wind turbines, cranes, excavators, mechanical engineering plants of all kinds and tunneling machinery. The functional diversity of our slewing bearings is already apparent in their dimensions: thyssenkrupp Bearings supplies slewing bearings up to 18 meters in diameter.
Rotek manufacturers rothe erde® slewing bearings in our Aurora, OH and Florence, KY facilities.
With a focus on high demanding applications, customized psl® industrial roller bearings drive a level of perfection and great performing capability rarely seen in the global bearing marketplace.
We manufacture excellence in customized bearing solutions.
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. PSL ULTIMATE Class bearings bring enhanced performance with improved higher load carrying capacity or enable down-sizing of a design. The dimensional range of psl® rolling bearings exceeds 2 meters in outer diameter.
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 product range is continuously expanding depending upon the requirements of the market. The product range includes thrust ball, tapered and cylindrical roller bearings. For rotating tables with machine tools requiring a high degree of accuracy, psl® developed a line of precise crossed tapered roller bearings. In recent years, psl® invested significant financial means into extending production capacity as well as in upgrading the technology for production of bearing rollers. This investment was mainly focused upon the area of turning, grinding, sorting and inspection of bearing rollers. Modern production and testing devices allow production of bearing rollers with high accuracy.

No.
Our people, our expertise as well as 55+ years of manufacturing and engineering excellence aren’t going anywhere. The bearings and rings we manufacture are still produced from machines and our people in Aurora, OH and Florence, KY. The bearings and rings we are producing will be labeled as rothe erde® bearings and rothe erde® rings. That’s the only thing changing.
