Rotary Union Model 2620

Model 2620 Rotary Unions feature two independent passages, making them suitable for CNC machine applications (e.g. unclamping, workpiece sensing, and cooling), in addition to a variety of machinery applications.

 

Balanced mechanical seals, with silicon carbide seal faces, provide long service and reduced operating torque. Closed seals allow continuous containment of media and labyrinth, protecting bearings from the media being transmitted. These rotary unions are available with a variety of mounting configurations.
