The "Pearl Rotary Joint SM Series" is a rotary joint that is resistant to dirty fluids containing foreign substances such as rust in the piping. It features a protective tube that reduces the likelihood of sticking in the sealing mechanism and biting on the sealing surface due to foreign substances, making it less prone to contamination. This helps maintain the sealing function for a longer period. Additionally, we offer rotary joints with sealing materials that reduce wear on the sealing surface depending on the type of foreign substances, as well as sealing mechanisms designed to be less affected by foreign substances. To ensure stable use of the rotary joint, please install a strainer or filter. *Please feel free to contact us.

The "Pearl Swivel Joint SRK/SSH Series" is a pressure-refracting joint that smoothly transports fluids with a stable sealing mechanism. By arranging the flow path between the left and right radial ball bearings, thrust loads from fluid pressure do not act on the bearings. This allows for use in high-pressure ranges, and the variation in dynamic torque due to pressure changes is minimized. The sealing section uses an O-ring with a special backup ring, and the bearing section incorporates two radial ball bearings, providing significant mechanical strength. 【Features】 ■ Simple structure and easy maintenance ■ High mechanical strength ■ Stable operation due to excellent pressure design Flange-type joints can also be manufactured. *For more details, please refer to the catalog or feel free to contact us.
