Premium Couplings for Industrial Power Transmission – Part 1

As modern industries evolve, the demand for high-performance, reliable coupling continues to grow. At Dai Hong Phat Corp, we provide a wide range of mechanical couplings for industrial applications, offering customized solutions for various load conditions, torque requirements, and operational environments.
With more than 15 years of experience, we are a trusted distributor of global coupling brands such as Ringfeder, KTR, Rathi, and Westcar in Vietnam.

1. What Are Couplings?

Coupling is mechanical components used to connect two shafts in a drive system, transmitting power while accommodating misalignment, vibration, or thermal expansion. They play a crucial role in maintaining machinery performance and minimizing downtime in motors, gearboxes, pumps, compressors, and conveyor systems.

2. Types of Couplings Available at Dai Hong Phat:

2.1. Flexible Couplings

Flexible coupling is ideal for applications that require misalignment compensation and vibration damping. These couplings absorb shocks and reduce stress on connected equipment, increasing the lifespan of your system.
Common types include:

• Elastomeric jaw couplings (e.g., Rotex® KTR, TNM Ringfeder, RRJ Rathi)
• Grid couplings (e.g., T10-20-31 PTI)
• Pin and bush couplings (e.g., RB Rathi, Rupex Flender,..)
• Jaw couplings for servo application (e.g., Rotex GS KTR, GWE 5113 Ringfeder,..)
• Rubber shaft coupling (e.g., Sure-Flex TB Woods, Dynamic Woojin,..)

2.2. Gear couplings

Gear coupling is high-torque, torsionally rigid shaft connections made up of two gear hubs and a sleeve (or two sleeves) that connect them. The external teeth of the hubs mesh with the internal teeth of the sleeve(s), allowing torque to be transmitted while also compensating for limited misalignment.
Gear coupling currently available in our warehouse include TNZ ZCA Ringfeder, Gearex KTR, SSM JAC and more
High Torque Transmission with Gear Couplings

Gear coupling like the TNZ ZCA series by Ringfeder are ideal for high torque transmission in heavy-duty machinery. With crowned gear teeth and high misalignment capacity, they deliver maximum efficiency in demanding environments such as:

• Cement plants
• Steel production
• Marine propulsion systems

2.3. Disc Coupling

Disc coupling is known for their high torsional rigidity and zero-backlash performance. These couplings are perfect for servo drives and motion control systems that demand precision and stability.
Our featured product:

• TND XSX Steel Disc Coupling by Ringfeder –  Ideal for applications requiring accuracy and minimal maintenance.

3. Industrial Couplings for Every Application

Dai Hong Phat Corp supplies industrial couplings suitable for a wide range of sectors:

3.1. Coupling for Pumps and Compressors

High-performance couplings used in pumps and compressors must withstand continuous operation, high torque, and thermal stress.
Our Rathi B-Flex or Ringfeder TNM or KTR Roflex couplings are designed to handle such conditions effectively.

3.2. Coupling for Cranes and Hoists

Our Barrel Couplings TNK and Westcar hydraulic coupling provides robust solutions for cranes and hoists. They ensure smooth torque transmission and protect gearboxes from overload and shock loads during lifting operations.

3.3. Coupling for Conveyor Systems

In conveyor applications, torsional flexible couplings help reduce torque peaks and compensate for misalignment, ensuring continuous operation in manufacturing lines, logistics, and material handling.
Ringfeder TNR couplings are designed to handle such conditions effectively.
