A Swivel is a mechanical device used on a drilling rig that hangs directly under the traveling block and directly above the kelly drive, which provides the ability for the Kelly (and subsequently the drill string) to rotate while allowing the traveling block to remain in a stationary rotational position (yet allow vertical movement up and down the derrick) while simultaneously allowing the introduction of drilling fluid into the drill string.Parts: bail, Gooseneck, upper shell, body, lower shell, swivel stem, shaft, sealing system, etc.

A Swivel is a mechanical device used on a drilling rig that hangs directly under the traveling block and directly above the kelly drive. It provides the ability for the kelly and the drill string to rotate while allowing the traveling block to remain in a stationary rotational position. At the same time, it allows vertical movement up and down the derrick and facilitates the introduction of drilling fluid into the drill string.
Swivels are essential components in drilling operations, ensuring efficient and uninterrupted rotation of the drill string while maintaining proper fluid circulation. These devices support the drill string's dynamic movements and improve the overall operational efficiency of drilling rigs.
The key components of a swivel include:
Bail – The component that connects the swivel to the traveling block, allowing free movement.
Gooseneck – A high-pressure passage that connects to the mud hose for fluid injection.
Upper Shell & Lower Shell – Protects internal components and ensures structural integrity.
Body – Houses the main operating components.
Swivel Stem – A central rotating component transferring torque from the kelly drive.
Shaft – Supports load transfer and rotation stability.
Sealing System – Prevents fluid leakage and ensures a pressure-tight operation.
The specifications of different swivel models are outlined in the following table:
High-load-bearing capability
Efficient fluid passage system
Robust sealing system to prevent leakage
Compatible with various mud pumps
Designed for heavy-duty drilling operations
Swivels are critical to the smooth operation of a drilling rig, ensuring that the drill string rotates effectively while maintaining fluid circulation and reducing stress on the equipment. High-quality swivels improve operational efficiency, reduce maintenance downtime, and enhance safety.
Swivels are securely packaged in durable materials to prevent damage during transportation. Standard shipping includes:
Protective wrapping for all components
Custom wooden crates for international shipments
Optional shipping insurance for added security

The main types of sucker rod couplings are sucker rod couplings, polished rod couplings and sub-couplings.
Sucker rod coupling has same box thread size in both end.
Sub-coupling has different box thread size in each end.
Polished rod coupling has the same box thread and vanishes cone on both ends.
All the three types have two classes: class T and class SM.
The outer diameter of the sucker rod couplings has a full size and slim hole types…
| Spec | Internal thread spec | Length | Outside diameter | |
|---|---|---|---|---|
| Full size | Slim hole | |||
| 5/8" | 15/16" | 4" | 38.1mm | 31.8mm |
| 3/4" | 1-1/16" | 4" | 41.3mm | 38.1mm |
| 7/8" | 1-3/16" | 4" | 46mm | 41.3mm |
