Engineered Solutions for Every Application

Industries

Deublin rotary unions and electrical slip rings are used by all kinds of industrial machinery and manufacturing processes. 

Why We're Different

Deublin offers different sealing technologies to handle virtually any combination of media, rotating speed, and pressure. Find the best solution for your needs. 

Pop-Off® Sealing Technology

Deublin's unrivaled Pop-Off® technology seals metalworking fluids, including MQL, up to 2000 psi but separates the seals when fluid pressure is turned off, thereby eliminating seal wear due to dry running.

AutoSense® Sealing Technology

Deublin's patented AutoSense® technology is unique in sealing both conventional coolant as well as unlubricated air with no risk of premature seal damage from dry running.

SpindleShield® Technology

Deublin's patented SpindleShield® technology signals the machine that spindle contamination is emanate, avoiding costly downtime.
