SGK Swivel Joint

SGK is a Japanese famous brand for rotary joint & swivel joint

Swivel Joints are metal are metal pipe fittings with integral ball-bearing swivels.
End connections are female threaded or  flanged.

In various fields of industry,”pearl”(SGK’s brand name) swivel joints have been successfully used under variety of service conditions covering a wide range of materials,pressures,temperatures and swivel moments.
Pearl Swivel Joints are used when compressed or decompressed (below atmospheric pressure) fluid/gas is transported and the piping needs to be rotated or moved in optional direction of up/down, left/right, or forward/backward. Movable piping can be made easily, safely and at a low cost, and piping can be secured.
These Swivel Joints can be rotated 360 degrees.
They have large mechanical strength that endures large radial/thrust load and moment load due to double-row ball bearings and grease lubrication.
Since a ring-type packing such as O-ring is used in the sealing section, the structure remains simple while providing stable sealing that does not leak any pressurized fluid contained.PK series, for high temperature application is incorporated with lubrication-free bearings section, and the sealing section adopts PTFE material and the mechanical seal to provide stable sealing.

Applications

1. Style 2 (or Style 1)

As shown below, they are used for transporting fluid to a rotating body.

● Example:
Hose reel,Rotary coil hooker,etc.

2. Style 2

As shown below, they are used when fluid is transported through rubber hose or flexible metal hose. Damage to the bending section generated by mechanical movement can be eliminated and the hose length reduced.

● Example:
Construction machines,Machine tools,Hydraulic systems,Cargo-handling systems,etc.

3. Style 3-3-3 (or Style 2-3-2)

As shown below, dreg piping capable of planar movements can transport fluids from a fixed set of piping to a moving machine safely and with assurance.The use of six swivel joints allows the piping to be moved in all directions (in three dimensions).

● Example:
Hot press,Tire press,Die-cast machine,Injection molding machine,etc.
