High voltage high-speed rotary joint
introduction:
Our high pressure high speed rotary union (rotary joint) is engineered to deliver continuous media transmission between rotating and stationary parts. Adopting high-strength aluminum alloy housing and advanced precision sealing components, it features low friction torque, stable operation, and zero leakage under high rotation speed and high pressure conditions.
This single-passage rotary joint is mainly designed for CNC machining center spindle through-coolant systems, deep hole drilling, and can transfer coolant, compressed air and cutting fluid. Threaded connection enables simple installation. Custom specifications and OEM service are available to match your machine requirements.
Structural description
Single channel for coolant or MQL
Technology allows unlimited dry operation without medium pressure
Full flow design, unobstructed passage, avoiding residual impurities
The threaded rotor supported by bearings is easy to install
Double angle contact ball bearing
Maze structure and multiple large leakage ports to protect ball bearings
The balanced mechanical seal uses silicon carbide, which has a long service life, even under harsh operating conditions
Anodized aluminum shell for corrosion resistance
Product Description:
1. Detached sealing technology;
When there is pressure, it can be closed; when there is no pressure, it can be released for a short period of time; Dry operation”;
3. Bearing support and threaded rotor, easy to install;
4. Adopting labyrinth seal and large leakage port to protect ball bearings;
5. The shell is made of aluminum alloy, which has good heat dissipation effect at high speeds;
Speed: 15000r/min Pressure: 8.0MPA Medium: Hydraulic oil, cutting fluid
Expected use:
The rotating joints of the 902, 903, 1109, 1110, 1111, 1121, 1151, and 1129 series are designed to provide cooling lubricant to rotating tools. During periods of stillness, compressed air can usually be used
The tool fixing area for removing chips. Rotating joint design for operation at ambient temperature
Temperature and medium temperature range from 3 ° C to 3 ° C; C to high. 70° C。
Definition of media:
❑ Coolant‐ It is a lotion composed of water and oil-based additives
Cutting oil
❑MQL – Minor lubrication
For information on the working parameters and dimensions of rotary joints, please refer to
Catalog or model specific installation diagram.
The specified rotating joint design is used for non explosive environments and non flammable media.
