Spectrum Drilling Tools International manufactures a diverse range of Rotary Adapter Ring and Reducer Bushings designed to fit 75.1/2”, 60.1/2”, 49.1/2”, and 37.1/2” Rotary Tables. These Reducer Bushings can come in either solid or split designs, and their configurations can vary from matching the same maker of the rotary table (e.g., LTI-LTI) or adapting from one brand to another brand (e.g., OILWELL-NATIONAL).
