China Hot selling Bucking Unit for Coupling and Screwing Threads of Tubulars encoder coupling

Product Description

Bucking Unit with Power Station and Torque Control Panel / Make up and Break out Machine

Product Description

JX180-35 premium thread tubing/ casing coupling bucking unit is the special equipment applied to the processing of premium thread oil pipe. It is also applied to the coupling screw of the premium thread such as FOX, NK3SB, VAM, BGT as well as the common thread.
With a slight mark and the depth of being less than 0.1mm, the floating arm tong is able to inspect the make-up torque precisely and display the torque of the inflection point clearly during the make-up process. It changes speed automatically during the make-up process and the low rotation speed is lower than 10r/min. It is thus applied to the processing demand of premium threads.

The stepless speed change can be realized by adjusting the power tong to rotate at any speed within the range of 0.5r/min~12.5r/min in combination with the electrical control system and hydraulic power system. During making-up, the speed inversely slows down as the torque increases, it rotates at a high speed when the torque is small for the purpose of ensuring the making-up efficiency, when the torque is large, the speed will steadily slow down, which strictly meets the API Specification, ensuring the making-up process not exceed the set torque.

What Is a Coupling?

A coupling is a mechanical device that links two shafts together and transmits power. Its purpose is to join rotating equipment while permitting a small amount of misalignment or end movement. Couplings come in a variety of different types and are used in a variety of applications. They can be used in hydraulics, pneumatics, and many other industries.


Coupling is a term used to describe a relationship between different modules. When a module depends on another, it can have different types of coupling. Common coupling occurs when modules share certain overall constraints. When this type of coupling occurs, any changes to the common constraint will also affect the other modules. Common coupling has its advantages and disadvantages. It is difficult to maintain and provides less control over the modules than other types of coupling.
There are many types of coupling, including meshing tooth couplings, pin and bush couplings, and spline couplings. It is important to choose the right coupling type for your specific application to get maximum uptime and long-term reliability. Listed below are the differences between these coupling types.
Rigid couplings have no flexibility, and require good alignment of the shafts and support bearings. They are often used in applications where high torque is required, such as in push-pull machines. These couplings are also useful in applications where the shafts are firmly attached to one another.
Another type of coupling is the split muff coupling. This type is made of cast iron and has two threaded holes. The coupling halves are attached with bolts or studs.


The coupling function is an incredibly versatile mathematical tool that can be used in many different scientific domains. These applications range from physics and mathematics to biology, chemistry, cardio-respiratory physiology, climate science, and electrical engineering. The coupling function can also help to predict the transition from one state to another, as well as describing the functional contributions of subsystems in the system. In some cases, it can even be used to reveal the mechanisms that underlie the functionality of interactions.
The coupling selection process begins with considering the intended use of the coupling. The application parameters must be determined, as well as the operating conditions. For example, if the coupling is required to be used for power transmission, the design engineer should consider how easily the coupling can be installed and serviced. This step is vital because improper installation can result in a more severe misalignment than is specified. Additionally, the coupling must be inspected regularly to ensure that the design parameters remain consistent and that no detrimental factors develop.
Choosing the right coupling for your application is an important process, but it need not be difficult. To find the right coupling, you must consider the type of machine and environment, as well as the torque, rpm, and inertia of the system. By answering these questions, you will be able to select the best coupling for your specific application.


A coupling is a device that connects two rotating shafts to transfer torque and rotary motion. To achieve optimal performance, a coupling must be designed for the application requirements it serves. These requirements include service, environmental, and use parameters. Otherwise, it can prematurely fail, causing inconvenience and financial loss.
In order to prevent premature failure, couplings should be properly installed and maintained. A good practice is to refer to the specifications provided by the manufacturer. Moreover, it is important to perform periodic tests to evaluate the effectiveness of the coupling. The testing of couplings should be performed by qualified personnel.
