Applicable industry: Steel NJ type
Rotary Joint
Concept
The rotary joint NJ type was developed as a long-life and reliable functional component in response to the longer segment maintenance cycle of continuous casting equipment in the steel industry.
Model
Features
-
-
Adoption of metal spring type mechanical seal structure
The metal spring is located at non-wetted area.
So, it can be used stably without affected by bad fluid quality.
-
Reliable bearing support structure
Durable to the tensile load from flexible hose.
-
Long life
Long life due to mechanical seal structure.
-
Low torque
Metal spring system reduce rotating resistance.
