A rotary table is a piece of rig equipment sometimes referred to as a turntable. The majority of rotary tables or turntables are driven by a chain (much like a heavy-duty bicycle chain). This chain needs to be kept well lubricated, in order to stop it from seizing up.

Most rotary tables, including the refurbished National C-495 rotary table we have for sale, are fitted with a rotary lock. When this lock is engaged, it can stop the turntable from moving at all, or just in one specific direction. A National rotary table might be used by rig crew instead of tongs, to facilitate the fabrication of break out pipes.

Maintenance of this type of rig equipment is pretty straightforward. There are rotary bushings in the middle of the turntable. It is these bushings that are connected to kelly bushings to produce the rotation needed for drilling. Removing these bushings allows other pieces of rig equipment, such as drill bits, to be pushed through the turntable. The hole in the middle of the National C-495 rotary table is known as the bowl. The bowl is where slips are put, to keep the drill string held up during connections and pipe trips.

Below, is the Certificate of Compliance for this National Oilwell rotary table. It was issued in 2013 by American Block. We have also included recent photographs of the turntable.

In general all the tables can be equipped with a clamping system on the rotating B-axis. The system is designed in such a way that it does not modify the angular position of the table during the clamping phase.

The LER rotary electric actuators feature a rotating worktable positioned above an enclosure for the motor and drivetrain.

Additionally, each size offers four rotating angle options, including 90°, 180°, 310 / 320°, and continuously rotating.
