detail
The CNC machining center water outlet rotary joint is a high-speed fluid sealed transmission device designed specifically for the internal cooling system of machine tool spindles. Its core function is to continuously and leak free coolant (water/emulsion) from stationary pipelines into the high-speed rotating spindle center hole, achieving internal cooling and chip removal of the tool
detail
Deep hole drilling high-speed rotary joint is a key fluid dynamic sealing device designed specifically for deep hole machining machines such as gun drills, BTA drills, spray suction drills, etc. Its core function is to transfer high-pressure coolant or hydraulic oil from a stationary pipeline system to the rotating drill rod without leakage while the spindle rotates at high speed, in order to achieve chip removal, cooling, and lubrication, ensuring the accuracy and efficiency of deep hole machining
detail
The 902 series is a single channel "detachable" rotary joint designed for machine tool coolant or MQL (micro lubrication) working conditions, with the core feature of Pop Off ™ Technology can achieve infinite dry operation without medium pressure, preventing seal damage.
detail
The A10 series high-speed rotary joint is a high-speed center outlet/air type joint developed specifically for CNC machine tools, deep hole drilling, and automation equipment. Its core feature is to support switching between wet operation and high-speed dry operation
detailFrom precision machining to seal testing, every step follows international standards (ISO 9001, CE, ATEX) — delivering reliable fluid transfer solutions for paper, steel, chemical, rubber, and plastics industries.
High-precision CNC machining centers with micron-level tolerances ensure rotational stability and seal integrity, even at high speeds and demanding operating conditions.
316L stainless steel, alloy steels, silicon carbide, and carbon graphite — selected for maximum corrosion resistance, wear resistance, and compatibility with steam, hot oil, water, and air.
Balanced seal design with silicon carbide/graphite seal rings delivers ultra-low leakage rates under high-temperature and high-pressure conditions, ensuring extended service life and reduced maintenance.
20+ years of rotary joint engineering experience — offering customized design, sizing guidance, material selection, and on-site technical support for your specific application.
SDSWIVELES integrates 20 years of engineering experience with German-inspired quality management systems to form a standardized production process for precision rotary joints.
Every rotary joint undergoes a documented manufacturing sequence: precision CNC machining, seal face lapping, assembly, and final inspection. Each unit is traceable with individual quality records and serialized documentation.
Our quality department operates with full independence and authority to halt production if standards are not met. Dimensional tolerances are verified to ±0.01mm, and all units are pressure-tested to 1.5x working pressure before shipment.
Triple validation: "dimensional reports + material certifications + performance test records." Product qualification rates remain stable above 99%, eliminating performance variations and ensuring long-term operational reliability.
