Pearl Swivel Joint

Swivel Joint

SRK/SSH Series
CATALOGPearl Joint ー Pearl Rotary Joint ーSRKSeries
SSH Series
FeaturesBy locating the flow passage between the left and right radial ball bearings, thrust loadcaused by fluid pressure is not applied to the bearings. Thus, it is possible to use the productin a high-pressure range, with small variations in dynamic torque due to pressure changes.

O-rings (with back-up rings) are used as main seals, providing stable seal performance in arange of low to high pressure.

Precautions on Selection

1.

Select a product whose operating conditions are within the service conditions (listed in the table on page 2).

2.

Two radial ball bearings are incorporated in a product and there is no clearance (play). Shaft movement is 		restricted in the swivel direction. When introducing a hose for connecting the product or a movable pipeline forusing multiple products, carefully consider the motion of the hose and the movable pipeline before selecting a style.

3.

Select an option as necessary.
1) See “Model Names and Types” (page 6) for the types of options.

4.

The standard specification main seal (NBR) cannot be used for phosphoric ester-based hydraulic oil, chlorinatedhydrocarbon-based hydraulic oil, organic solvents, or acids. Contact us for a substitute seal.

5.

The use of the product in a continuous rotation condition is not appropriate. The product lifetime becomes shortened.

6.

The product cannot be used for fluid that causes corrosion on it.

7.

The product is not designed according to the general design rules for safety and hygiene of food processing 		machinery (JIS B 9650). Consult with us when considering the use of the product in food-related facilities.

8.

Depending on the fluid used, the product may subject to restrictions due to national laws or local regulations.
As for customized products, we can produce products with modifications that are not included in the options, 		
including such products for which a flange, socket welding, or butt welding is used for connection.
If you have any questions or wish to purchase customized products, contact our sales representative.
