分体式高速主轴旋转接头

The split type high-speed spindle rotary joint is a fluid transmission sealing component designed specifically for ultra high speed machine tool spindles. It adopts a stator and rotor separation structure, which solves the dynamic balance and heat dissipation bottleneck of traditional integrated structures at high speeds. ‌‌

Intended 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.
