In various fields of industry,"pearl"(SGK's brand name) rotary joints have been successfully used under variety of service conditions covering a wide range of materials,pressures,temperatures and speed. SGK Pearl Rotary Joints are used for supplying/discharging compressed or decompressed (below atmospheric pressure) fluid/gas from a fixed piping to the rotary section of various machines with no leak. For example, SGK can be used when a heat transfer medium such as <steam>, <hot water>, or <heated oil>, or a coolant such as <water>, <brine>, <ammonia>, or <Freon> for cooling is supplied to rotating [roll], [drum], or [cylinder], and when <compressed air> or <operating oil> is supplied to rotary machines such as [clutch] and [chuck] that are operated by fluid/gas. SGK rotary joints have been developed based on the most recent and advanced mechanical seal theory, and are extremely effective and economical. SGK are manufactured under strict quality control, and are compatible to one another with no deviation in the product. Furthermore, with rich line-up of models, SGK can satisfy various purposes.

Example: for Water or Thermoil Plastic extruder,Film cooling and take-up roll,Rubber kneading machine,etc. Example: for Steam Paper dryer,Plastic calender,Double drum dryer,etc. 3. Duplex,Rotational Internal Pipe Where the internal pipe rotates simultaneously with a roll,the rotary joint must have another seal for the internal pipe. Example: Drilled roll,Film machine,etc.
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 speed 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.SGK Swivel Joints can be rotated 360 degrees. SGK 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.
