Rotary Table: The Power Behind Every Drilling Rig

In oil and gas drilling, efficiency and reliability begin at the rig floor — and the rotary table is its beating heart.
This heavy-duty component provides the rotational drive to the drill string, ensuring smooth, continuous drilling operations.
If you are looking for a trusted rotary table supplier or API certified drilling rig equipment manufacturer from China, this guide will help you understand its structure, standards, and selection criteria.

What Is a Rotary Table?

A rotary table is a mechanical device mounted on the rig floor that transmits torque to the drill string through the kelly bushing and kelly drive system.
It provides the rotational motion required for drilling while supporting heavy axial loads from the drill pipe and tools.

Key Functions:

Drives the drill string with continuous rotation.

Supports the full weight of the drilling assembly.

Interfaces with the kelly and bushing for torque transfer.

Designed for safety, durability, and ease of maintenance.

Technical Standards & Certifications

All rotary tables are designed and tested according to international standards:

• API Spec 7K – Drilling and Well Servicing Equipment.
• ISO 9001 / ISO 14001 – Quality & Environmental Management.
• NACE MR0175 – Material resistance for sour service (optional).

Each unit undergoes load testing, torque calibration, and non-destructive inspection (NDT) before delivery.

Types of Rotary Tables
