LX84-7920 rotary joint

Applicable scenarios: Designed specifically for CNC machine tool spindle center water/oil discharge, supporting the transmission of coolant, lubricating oil or compressed air, commonly used in high-speed machining centers of brands such as MAZAK and Little Giant.
Working parameters: Typical pressure resistance of 0.5-7 MPa, speed up to 3000 RPM or higher, temperature range of -20 ° C to+100 ° C (depending on the sealing material).
Sealing technology: using silicon carbide/carbon graphite wear-resistant sealing pair, supporting high-speed dry operation and high-pressure working conditions, with low leakage.
Structural features: Built in shielded ball bearings, no lubrication maintenance required; Dual channel or central outlet structure, conducive to vertical installation and drainage; The main body is mostly made of stainless steel (such as 304/316L), which is corrosion-resistant.
Interface form: commonly G1/4 “or G1/2” threads, which need to be matched with the spindle port of the machine tool; Installation requirements include high coaxiality, flexible hose compensation, and prohibition of hard connections.
