1101-265-239 rotary joint is a standard model of the 1100 series rotary joint, used for sealed transmission of single media (such as coolant, steam, oil, etc.) in rotating equipment. The interface is G1/4 "radial (20mm diameter), suitable for medium and high speed, medium pressure working conditions
detail
1101-265-343 rotary joint is a single channel, closed sealed, radially connected coolant rotary joint belonging to the 1101 series, suitable for coolant or micro lubrication (MQL) applications on high-speed machine tool spindles
detail
1101-265-644 rotary joint is a 1101 series "closed seal" single channel coolant/micro lubrication (MQL) rotary joint, which adopts G1/4 "radial supply, silicon carbide sealing, bearing support structure, and is dedicated to the transmission of coolant or oil mist medium for high-speed machine tool spindles
detail
The 1116-516-463 rotary joint is a "closed seal" continuous coolant rotary joint designed specifically for single channel coolant or micro lubrication (MQL) applications
detail
1116-063-463 rotary joint is a bearing supported coolant rotary joint designed specifically for machining centers, gun drills, and deep hole machining equipment. This model belongs to the 1116 series and adopts a "closed seal" design, suitable for continuous coolant or micro lubrication (MQL) applications
detail
Professional SKT center outlet rotary joints exclusively for CNC lathes, milling machines and machining centers. Adopting wear-resistant sealing and anti-clog flow channel design, ideal for long-cycle high-speed spindle cooling and oil mist lubrication systems.
detail
SRJ01-2005 belongs to single or double path high-speed rotary joints, designed specifically for spindle cooling systems in CNC machine tools and machining centers. Its core function is to transport cutting fluid, hydraulic oil, or air from a stationary pipeline to the interior of a high-speed rotating spindle, in order to achieve tool cooling, chip removal, or pneumatic clamping
detail
GAT (such as Rotodisk SW/S series): using static hydraulic self compensating silicon carbide/ceramic seals, supporting up to 200-400 bar pressure and 100000 rpm speed (depending on the model), non-contact or micro gap sealing structure to achieve extremely low friction and zero leakage (dynamic ≤ 0.01 mL/h), the body is mostly made of high-precision steel or stainless steel
detail
ESX20M-756YSUS high-speed rotary joints are SUS stainless steel precision unions customized for CNC machine tools. Boasting anti-corrosion, low torque and vibration-resistant design, they support stable, leak-free high-speed transmission of coolant and oil mist for precision machining.
detail
ESX20M-8080YSUS series of bearingless rotary joints consists of a fixed part ha installed in a protective cover and a rotating part of the main shaft, without bearings. Due to the absence of built-in bearings, the vibration of this series of rotary joints is small, and their compact size contributes to the miniaturization of machine tools
detail
ESX20M-E016 flange connection high-speed rotary joints feature stable flange mounting structure and precision sealing system. Designed for high-RPM industrial equipment, these heavy-duty rotary unions deliver leak-free coolant and oil mist transmission with excellent vibration resistance.
detail
Troubled by spindle seal wear and fluid leakage during continuous operation? LX84-7920 rotary joints adopt optimized low-friction design, effectively resisting cutting fluid impurities and extending service life for precision machining equipment.
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.
