The  1117 connector is used on high-speed spindles in today’s high-tech automatic lines. The speed of this joint can even exceed the speed range of metal ball bearings. The 1117 model adopts external support and does not require internal bearing support at all. The rotating short shaft is directly installed at the main shaft end, while the main body is rigidly installed on a fixed surface and aligned with the rotating body. In fact, the joint has now become a vibration free integral part of the spindle component. Due to the adoption of a bearingless design structure and a highly wear-resistant silicon carbide seal, the joint can achieve low torque and smooth operation, thereby achieving a long and trouble free service life. Another characteristic of the 1117 model is its compact structure, which allows for easy design based on existing equipment.

Introduction to 1117 series bearingless coolant high-speed rotary joint products
Product Overview
The 1117 series rotary joint is a single channel bearingless rotary joint developed by Deublin Corporation in the United States, specifically designed for high-speed and high-precision machining applications. This series of products adopts an innovative “bearingless” design, which eliminates the rolling bearing structure in traditional rotary joints, significantly reducing frictional resistance and achieving extremely high speed performance. Its core application scenarios include automated production lines, CNC machine tool center water outlet systems, and industrial environments that require continuous delivery of coolant or micro lubrication (MQL) media.
Core technical features
1. Bearingless high-speed design
Traditional rotary joints are limited by the maximum speed of bearings, while the 1117 series uses fluid dynamics principles and precision sealing technology to support the rotor by removing bearings. This design extends its speed range from 10000 rpm to 50000 rpm, meeting the stringent cooling efficiency requirements of modern high-speed cutting machining.
2. Closed balanced mechanical seal
Material advantage: The balanced mechanical seal ring is made of silicon carbide material. Silicon carbide has extremely high hardness, wear resistance, and thermal conductivity, and can maintain a very low wear rate even under harsh working conditions, greatly extending its service life.
Sealing form: The closed sealing design effectively prevents external impurities from entering the internal flow channel, while ensuring that the medium does not leak out, especially suitable for automatic line applications with high cleanliness requirements.
3. Full flow barrier free passage
The internal flow channel has been optimized and designed to achieve a fully flowing structure without any obstacles. This design avoids the residue or blockage of chips, burrs, or impurities inside the joint, ensuring stable flow of coolant or MQL medium and reducing maintenance frequency.
4. Compact and corrosion-resistant structure
Shell material: Made of anodized aluminum shell, it has excellent corrosion resistance and can adapt to humid and chemically corrosive workshop environments.
Easy installation: With a compact structure and small size, it is easy to integrate and install in space limited machine tool spindles or tool systems. Supports multiple interface standards in both imperial and metric systems to meet the installation needs of different customers.
