    Abstract：In replacement of seal rings in traditional integrated swivel joint, all roll balls are removed one by one in order to separate the housing and shaft. However, it is very difficult to remove the balls because spring in seal rings will generate tension and such tension will be transmitted to the balls between shaft and housing, so it is very hard to get balls out from raceway, which will result in difficult replacement of seal rings. The new detachable swivel joint has a raceway separating from housing and it is easy to remove the housing and shaft in replacement of seal rings. Adoption of such detachable swivel joint can improve the efficiency of replacement of seal rings and reduce downtime greatly.
