Top 10 Rotary Joint Manufacturers in 2023


Country: USA

Founded: 1945

About the company:

In 1945, Luke Dule and Dick Lynn founded this company, which completely changed the operation and performance of rotating equipment.

They combined their surnames and named the new company DEUBLIN Company. Its first product was an innovative spinner design, including a balanced mechanical seal.

At that time, the most popular type of sealing mechanism was pressure type seal.

These seals rely on system pressure to maintain mating surface friction, which proved problematic when the equipment speed increased.

Especially for the printing press, the pressure type seal is easy to wear out rapidly.

Luke saw an opportunity to improve industry standards and the design was immediately successful.

By designing the mechanical seal as a rotary joint, Luke pushed the company to the forefront of the industry and promoted the development of Dublin, which has continued to this day.

In addition to the printing press, Luke continues to design joints for a wide range of applications, including air clutches, gear boxes, machine tool spindles, textile equipment, continuous casting machines, paper machines, polishing machines and rubber manufacturing machinery.

This design has proved to be so effective and reliable that almost any industry that needs to transport air, water, oil or hydraulic fluid from a fixed source to the rotating part of the equipment uses Dublin products.

A few years after the successful start of the company, Dick decided to focus on another business. He sold his shares to Luk Dublin, which was acquired by Helbige Group, a private industrial company headquartered in Switzerland, in 2019.
