Rotary table

Drilling Equipment & Components

The rotary table is a mechanical device located on the drill floor that provides rotational force to the drillstring. It consists of a rotating disk with a master bushing that grips the kelly or drill pipe, transferring torque to turn the bit. While historically the primary method of rotating the pipe, it also supports the weight of the drillstring when slips are set during connections.

In modern drilling, the Top Drive system has largely replaced the rotary table as the primary means of rotation because it allows for drilling with 90-foot stands rather than single 30-foot joints, improving efficiency. However, the rotary table remains a critical backup and is essential for specific operations, such as orienting tools or supporting the string during assembly.
