Swivel Joint

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.

SRK Series

SRK Series

  • With the excellent pressure balance design, thrust load generated from the internal pressurized fluid is balanced well so that excessive load is not added to the bearing. They endure extreme pressures and provide stable operation with little rotary torque fluctuations due to pressure.
  • Large mechanical strength due to an <O-ring> with special backup ring used in the seal seciton and 2 <radial ball bearings> contained in the bearing section.
  • Maintenance is easy, with simple structure and <O-ring> and <backup ring> being the only consumables.

Flange-type joints (SRK-2F and 3F) can also be manufactured upon request. Please inform the flange specifications.

We have SSH series made of SUS.

Max. Pressure 10A to 40A 34.3MPa
(4975 psi)
50A to 80A 24.5MPa
(3553 psi)
Max. Temperature 100 degrees C
(212 degrees F)
Material Steel (Weld Steel)
Seal NBR O-ring
Connection Female Taper Thread (Rc)

PK Series

PK Series

  • Self alignment make piping easy.
  • Easy handling and piping due to small size and light weight
  • No need for lubrication, easy to maintain

PK-*S series is also available. PK-*S series incorporates a spacer between the body and axis of rotation to reduce eccentricity of the axis of rotation.

PKZ series for alternating heating and cooling operations is also available upon request.
