Research & Development

Our Rotary Joints as the leading product are the rotating joints to transfer media (steam, water, air, etc.) from a stationary source into a rotating part of machinery, so it is required to supply media without any leakage.
Customer's operating conditions such as speed, temperature, pressure, etc. should be checked when having an offer or a consult on rotary joint. This is the first step for us. It is our technical know-how to select the optimum rotary joint for the customer's operating conditions. It sometimes happens that we develop a new typed rotary joint for customer's special operating conditions. Ultimately, it would not be too much to say that most of our rotary joints might be custom-made in accordance with customer's use.
