High pressure sealing: using silicon carbide silicon carbide or tungsten carbide sealing pairs, with a pressure resistance of 12-20 MPa (depending on the model), combined with an automatic lubrication structure, it can withstand the mixing of small iron filings in the coolant
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.
High speed adaptability: ESX20M, LX86V and other series support a maximum speed of 50000 min ⁻¹, suitable for high-speed machining centers, engraving and milling machines, and turning and milling composite equipment.
High pressure sealing: using silicon carbide silicon carbide or tungsten carbide sealing pairs, with a pressure resistance of 12-20 MPa (depending on the model), combined with an automatic lubrication structure, it can withstand the mixing of small iron filings in the coolant.
Central water outlet function: Achieve precise direct flow of coolant/oil mist/dry air (MQL) to the cutting edge of the tool, significantly reducing cutting zone temperature (extending tool life by about 30%), reducing iron chip entanglement (reducing by 80%), and improving surface smoothness.
Structural design: mostly of bearingless type (such as ESX20M series) or embedded bearing type (such as LX series), with a stroke of 8mm (optional 17mm), suitable for spindle internal pull rod structure; Card sleeve or threaded connection, stainless steel body corrosion-resistant.
Condition adaptation: Supports water-based/oil-based coolant, oil mist, and compressed air; Some models (such as LX86V) have the ability to operate dry (without coolant, they rely on special sealing shapes to dissipate heat and prevent leakage).
Maintainability: Modular bearing design allows for on-site replacement, reducing downtime costs; But it needs to be matched with the correct model (such as ESX20M-NO16, LX84-7920, etc.) and cannot be used interchangeably.
A rotary joint is a sealing device that connects stationary pipelines and rotating equipment, achieving leak free fluid transmission under 360 ° rotation. It allows fluid media to flow smoothly between fixed pipelines and rotating machines, and is a key component in industrial equipment
F90 swivel unions
Q32 swivel unions
JD40 rotary joint is a key sealing component in industrial fluid transmission systems, usually referring to a rotary connection device with a diameter of DN40 (or corresponding British caliber). As a transitional sealing device that transports fluid media (such as water, steam, hydraulic oil, thermal oil, compressed air, etc.) from static pipelines to dynamic rotating or swinging equipment
