Welcome to Rotek, the North American leader in the engineering, manufacture, service and support of large diameter slewing rings and seamless forged rings.

Rotek manufactures ball and roller type slewing rings in single-row and multi-row designs; with internal or external gearing or gearless; in diameters from 12 inches to 50 feet; in a wide range of capacities, materials and seals. Many slewing rings are available from stock or on short lead-times. Design assistance from Rotek is available, without charge, for any application.

In addition, we offer a variety of after-the-sale services and support programs, including slewing ring repair and on-site inspection, designed to help extend the life of your slewing ring.

Rotek also manufactures seamless forged rings in aluminum grades, carbon, stainless and alloy steels. All forgings are certified and traceable. Seamless forged rings are produced in outer diameters from 2 inches to 240 inches and weights to 35,000 pounds.

Rotek recently completed the installation of a new ring rolling mill as well as an addition to the slewing ring plant. These improvements give Rotek the ability to offer dimensionally consistent, competitively priced products.
