Mechanical Seal

The heart of the Rotary Union or rotary joint is the seal. The seal prevents the medium (water, oil, air, etc) from leaking outside the Rotary Union while the Rotary Union is in operation.

 

Bearing

The second most important part of the Rotary Union is the bearing. We use imported NSK double bearing. The bearings are always used to allow a part of the joint, either the shaft or the housing, to rotate smoothly and steadily.

 

 Shaft

The shaft is the component that carries the medium through the Rotary Union into the drum or roll. In many cases, the shaft will turn with the drum or roll. In some cases, like in larger flanged rotary Unions, the shaft may be stationary while the housing rotates. The bearings and seal are typically assembled around the shaft.

 

Housing

The housing is the component that holds all of the other elements of the Rotary Union together. The housing has an inlet port, which is a threaded port to which the hose supplying the medium will be attached. The Rotary Union may also have an outlet port, if the same joint is being used both to supply fluid to a roll and to remove fluid from the roll.  In these cases, the housing rotates at the same speed as the drum.
