Product Description

| Product introduction

The rotary joint adopts a one-piece structure of rotating shaft and body high-speed rotation balance mechanical seal, which coincides with the axis of the fluid pipeline (fluid flow direction) that transports different media. Widely used in all kinds of machining centers, automatic lines, gun drilling/gun hinge machine tools and other special equipment, for high-speed and high-pressure internal cooling transportation of coolant, cooling water, gas, oil mist, hydraulic oil, steam, oil and gas, vacuum and other media of high-performance, high-precision rotary joints. According to the needs of demand-side equipment, precision standard and precision economical rotary joint series can be provided.

| Product advantages

— Single-channel built-in, coolant or oil mist, suitable for machining center, automatic line large size spindle applications;
— Disengaged technology, using high-hardness silicon carbide sealing, can achieve pressure-cooling, pressure-free dry operation;
— Balanced mechanical labyrinth seal design, which can realize high-speed, medium and high-pressure full flow operation, strong reliability;
— Equipped with two NSK P5 precision deep groove ball bearings for smooth operation at high speed;
— It has the function of prepressing the elastic diaphragm of oil injection, liquid discharge and bearing to improve the service life;
— Hard aluminum anti-corrosion anodized housing, nitriding stainless steel rotating shaft and guide sleeve components;
— Pressure, speed requirements and bearing form are economical.
