The coupling sleeve is an indispensable part of rock drilling tools for rock drilling. During the drilling process, the coupling sleeve is at the joint part of the matching drill, which bears the corrosion effect of stress such as axial tension and compression, bending and torsion, contact, and friction.
The coupling sleeve used for threaded connection rock drill tools is to use its thread to connect two or more drill rods or shank rods on the same axis, transfer the impact function of the rock drill, and achieve the purpose of drilling rock holes, which is the same as the drill rod. It acts as a stress wave propagation carrier.
Coupling sleeve classification
1. Classification by the geometric structure
There are straight-through coupling sleeves, reducing coupling sleeves, and middle-stop-type coupling sleeves.
2. Classification by thread structure
There are coupling sleeves such as wave thread, compound thread, trapezoidal thread, etc.

COUPLING
Material: steel
Material grade: 20#,16Mn
Weight:5.69kg
Process:stamping+welding
Surface treatment:black painting
Description: A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting.

A forged coupling is a type of pipe fitting that is made by forging, a process that uses heat and pressure to shape metal. Forged couplings are typically made of steel, but they can also be made of other metals such as stainless steel, alloy steel, and copper.
Forged couplings are stronger and more durable than other types of pipe fittings, such as threaded couplings. They are also less likely to leak. Forged couplings are used in a variety of applications, including water, gas, and oil pipelines, as well as in industrial and construction applications.
Here are some of the technical specifications of forged couplings:
Material: Steel, stainless steel, alloy steel, copper
Class: 2000, 3000, 6000, 9000
Size: 1/8 to 4"
End type: Socket weld, threaded, flanged
Size: Typically available in sizes from 1/2 inch to 12 inches
We specialized as a manufacturer of all types of couplings for transferring torque and motion for machinery, such as gear coupling, flexible coupling, universal coupling, disc coupling, , grid coupling and rigid coupling etc,
