Suitable For Paper machines, paper rollers, casting machines, injection molding machines,

Flexographic printing machines, etc.

The Deublin rotary joint is typically used in industrial equipment where fluids (such as hydraulic oil, coolant, gas, steam, etc.) need to be transferred between rotating components and fixed pipelines.
The features of the Deublin 257 series
The Deublin 257 series rotary joint is a silicon carbide-sealed water medium application type joint. This type of joint is designed to solve the problem of wear at high-speed pipe network pressure. Its features include the use of super-hard sealing materials (such as silicon carbide), which have the property of being wear-resistant, and is usually repairable on-site.
According to the general characteristics of the Deublin 257 series, it can be applied in various industrial fields and mechanical equipment.
To present it more clearly, the following are the possible application fields and machine types for the Deublin rotary joint:
Paper industry: Paper machines, paper rollers, drying drums Transmit steam, hot oil or cooling water to rotating drums for temperature control
Plastics and rubber processing: Injection machines, extruders, calenders, rubber vulcanization machines Provide cooling water or hot media (oil/steam) to molds or rollers
Machine tools and machining centers CNC lathes, milling machines, grinders, deep hole drills Transport hydraulic oil (to drive tool towers, tailstocks, etc.) or coolant to the main shaft or rotating workpieces
Metallurgical and steel industry : Continuous casting machines (casting machines), rolling mills, winding machines Provide cooling water to roller bearing seats, or supply hydraulic power to rotating components
Printing industry: Rotating printing machines (such as intaglio printing, flexographic printing) Transmit water, ink or cleaning fluid to printing rollers
Other industrial machinery : winders, unwinders (unloading machines), packaging machinery (packaging equipment), textile machinery (textile equipment), automotive transfer lines (automobile production line transfer mechanisms) | Provide hydraulic, cooling or pneumatic functions for rotating units.
