Since its founding in 1962, Rotek has been the leader in large diameter slewing ring bearings in North America. Rotek offers a unique combination of experience and technology in designing large diameter bearings and seamless rolled rings. We've designed and manufactured thousands of slewing rings for a wide array of applications: power cranes and excavators, radar equipment and antennae stations, tunnel boring machines, offshore cranes, machine tools, industrial robotics and medical diagnostic equipment. Our extensive experience combined with the use of sophisticated CAD/CAM technology enables us to accurately predict final product capabilities and performance. Rotek’s design assistance is available through the on-line design worksheets on a no charge basis. Our team of application and design engineers will provide a preliminary design evaluation based on the application requirements you provide. Rotek’s experience in designing such a diverse range of slewing ring bearing and seamless rolled ring applications allow us to consistently deliver the most effective solution for your application.

Rotek’s integrated facilities provide complete manufacturing control.

We've complemented our application engineering experience with the latest in manufacturing systems and procedures. Rotek's fully integrated manufacturing facilities include two modern slewing ring plants and a state-of-the-art seamless ring rolling mill. Each facility utilizes advanced CNC and CAD/CAM technology, Total Quality Management disciplines, and Manufacturing Resource Planning (MRP II) systems. These fully integrated manufacturing facilities allow Rotek complete control over quality and scheduling, beginning with the raw materials and continuing through machining and assembly.
