This product is a swivel joint for piping with a heat-resistant coating on the exterior. It features a structure where the shaft and seal ring are tightly fitted by fluid pressure and a spring, sealing the fluid. The shaft can rotate 360 degrees in the swivel direction, allowing for compatibility with various options. 【Features】 ■ Automatic centering type for easy piping ■ Compact and lightweight for easy installation ■ No need for lubrication, making maintenance easy ■ Four styles available based on shape *For more details, please download the PDF or feel free to contact us.

The Pearl Rotary Joint "RX Series" is a product that exhibits high adaptability to the sealing surface of the rotor and stable sealing performance. Due to its low torque, in many cases, installation to prevent casing rotation is unnecessary. In addition to flange mounting, there are five types of screw mounting options available, providing a wide range of choices for connection with rolls. 【Features】 ■ No need for installation to prevent casing rotation due to low torque structure ■ A wide variety of product types including single, double fixed inner tube, and double rotating inner tube ■ Supports five types of screw mounting in addition to flange mounting ■ Stainless steel specifications with all metal parts made of stainless steel ■ Uses sealed ball bearings, eliminating the need for lubrication (RXE) *For more details, please download the PDF or feel free to contact us.

This product is a swivel joint designed for use in high-pressure ranges. By placing the flow path between the left and right radial ball bearings, thrust loads due to fluid pressure do not act on the bearings. As a result, changes in dynamic torque due to pressure variations are minimized. An O-ring (with backup ring) is used for the main seal, providing stable sealing performance from low to high pressure ranges. Two radial ball bearings are incorporated, ensuring there is no play. 【Features】 ■ Usable in high-pressure ranges ■ Minimal changes in dynamic torque due to pressure variations ■ Stable sealing performance from low to high pressure ranges ■ Structure with no play *For more details, please download the PDF or feel free to contact us.

We would like to introduce our Pearl Rotary Joint, the 'SXO Series'. We offer three styles: "90° Style," "Straight Style," and "Compact Style." Additionally, there are two types of mechanical seals available: a combination of special carbon and tool steel (Standard Seal) and a combination of carbide and ceramic (High-Grade Seal). 【Features】 ■ Lightweight and compact, easy to handle ■ Usable in high pressure and high rotation ranges ■ Standard Seal or High-Grade Seal can be selected according to application ■ High-Grade Seal is designed for high load applications *For more details, please download the PDF or feel free to contact us.

This product is a swivel joint that exhibits stable sealing performance and allows for smooth 360-degree rotation. The bearing section incorporates two rows of steel balls and is lubricated with grease. The bearing section is processed with high precision, eliminating any play, and the movement of the shaft is limited to the swivel direction. There are six styles available based on the combination of the body and shaft, and the material of the main seal and grease can be selected according to the fluid used and the application. 【Features】 ■ Incorporates two rows of steel balls in the bearing section, enabling smooth 360-degree rotation ■ Uses a ring-shaped packing for the main seal, providing stable sealing performance ■ Offers six styles based on the combination of the body and shaft ■ Allows selection of main seal material and grease according to the fluid used and application ■ Designed to prevent play with a high-precision processed bearing section *For more details, please download the PDF or feel free to contact us.

The "AC Series" is a rotary joint that can be used in high-temperature ranges (up to 180°C). A semi-standard specification that can be used above 180°C is also available. This product has minimal seal wear and maintains excellent performance for extended periods. The mechanical seal employs a combination of special carbon and carbon steel, and the exterior is coated with heat-resistant paint. It allows for alternating use of heating and cooling. 【Features】 ■ Usable in high-temperature ranges (up to 180°C) ■ Allows for alternating use of heating and cooling ■ Minimal seal wear, maintaining excellent performance for a long time ■ Mechanical seal uses a combination of special carbon and carbon steel ■ Heat-resistant paint applied to the exterior *For more details, please download the PDF or feel free to contact us.

The "KC Series" is a rotary joint that is compact, lightweight, and easy to install on rolls. It uses aluminum alloy for the casing and has an anodized (anodic oxidation treatment) finish. The mechanical seal is a combination of special carbon and stainless steel or carbon steel. Since it employs sealed ball bearings, there is no need for lubrication. Additionally, due to its low torque, there is no need for installation to prevent the casing from rotating. 【Features】 ■ Aluminum alloy used for the casing ■ Compact and lightweight, making installation on rolls easy ■ Sealed ball bearings eliminate the need for lubrication ■ Low torque means no installation needed to prevent casing rotation ■ Mechanical seal is a combination of special carbon and stainless steel or carbon steel ■ Casing has an anodized (anodic oxidation treatment) finish *For more details, please download the PDF or feel free to contact us.

The "NC Series" is a rotary joint that uses carbon bearings and does not require lubrication. This product can be used in high-temperature environments (up to 180°C). It has minimal wear on the mechanical seal, ensuring stable operation over a long period. The exterior is coated with heat-resistant paint, and the mechanical seal combines a spherical surface made of special carbon and carbon steel with a flat surface made of special carbon and cast iron. 【Features】 ■ Usable in high-temperature environments (up to 180°C) ■ Uses carbon bearings, eliminating the need for lubrication ■ Minimal wear on the mechanical seal, ensuring stable operation over a long period ■ Heat-resistant paint applied to the exterior *For more details, please download the PDF or feel free to contact us.

The "NX Series" is a rotary joint specialized for steam and thermal oil. The mechanical seal consists of a combination of a spherical surface made of special carbon and carbon steel, and a flat surface made of special carbon and cast iron, with a heat-resistant coating applied to the exterior. Since it uses carbon bearings, lubrication is not required. 【Features】 ■ Specialized for steam (NXE) and thermal oil (NXH) ■ No lubrication required due to the use of carbon bearings *For more details, please download the PDF or feel free to contact us.
