LX86V-234 high-speed rotary joint

Type and structure: Bearing built-in type (with embedded bearings and patented structure), dual drainage design to prevent coolant from infiltrating the bearing, supporting vertical/horizontal installation; The V-shaped suffix indicates suitability for high-speed operation with dry air, oil mist, or no coolant.
Speed capability: Conventional ≤ 15000 rpm, some materials mention specific configurations can reach 40000-50000 rpm (but not standard nominal values, configuration needs to be confirmed).
Pressure resistance range: 0.2-1.0 MPa (air)/0.2-1.0 MPa (coolant), some data mistakenly labeled 7-20 MPa (actually applicable to high-pressure variants such as LX86V-244); LX86V-234 standard withstand voltage ≤ 1.0 MPa.
Media compatibility: coolant (water-based/oil-based), dry air, oil mist (supports MQL); It is not recommended to use fluids containing chips or high impurities (although the seal is resistant to particles, it is not designed for heavy pollution conditions).
Sealing material: Silicon carbide ceramic seal (self-lubricating, wear-resistant), capable of short-term high-speed idling without coolant (but long-term dry running requires overheating prevention); Equipped with an automatic sealing opening and closing mechanism.
Working temperature: ≤ 60 ℃ (limited by sealing and bearing materials).
Flow rate: approximately ≤ 20 L/min (depending on the diameter and pressure difference).
Typical applications: Cooling fluid/gas, micro lubrication (MQL), and air tightness testing are used for the spindle center of high-speed machining centers such as Mazak and Senjing machines.
The product is widely used in many fields such as automobiles, metal processing, rubber and plastics, engineering machinery, walking machinery, metallurgical equipment, forging machines, environmental equipment, etc
Single channel coolant or MQL closed seal,

The automatic line is designed with full circulation similar to the application, without generating debris or burrs blocking
The bearing support has a threaded rotor, which facilitates the installation of deep groove ball bearings to ensure smooth operation,
The internal air path barrier can achieve a certain degree of dry operation
The silicon carbide tungsten carbide balanced sealing structure can meet the harsh operating environment,
Longer lifespan and better anti-corrosion effect of anodized aluminum shell.
