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.
