The high-pressure car washing machine rotary joint is simply a connecting piece that allows the high-pressure water pipe to rotate freely 360 °. Its core function is to prevent the water pipe from getting tangled or knotted, making it more flexible during car washing
detail
A rotary joint for coiling machine is a precision rotary sealing device that transfers fluids and gases between stationary supply lines and the rotating drum, spool, mandrel, or turntable of a coiling machine
detail
The main function of the centrifuge rotary joint is to input liquid from the pipeline into rotating or reciprocating equipment, and then discharge it from there. The design of this joint allows the equipment to maintain liquid transport even during high-speed rotation, ensuring the normal operation of the equipment
detail
The QR type heat transfer oil rotary joint is an efficient and reliable fluid connection device designed specifically for transmitting heat transfer oil in high-temperature environments. It is widely used in industries such as chemical, plastic processing, textile printing and dyeing, especially in processes that require precise temperature control and continuous operation. This article will provide a detailed introduction to the working principle, sealing structure characteristics, and advantages of QR type thermal oil rotary joints in practical applications
detail
The high-speed rotary joint of the expansion and contraction oil cylinder is a high-speed and high-pressure hydraulic sealing transmission component specially designed for the expansion and contraction hydraulic cylinder of metallurgical coiling/uncoiling machines
detail
SK type high-temperature heat transfer oil rotary joint is a spherical sealed mechanical connection device designed specifically for heat transfer oil media. The core adopts dual carbon graphite oil-free bearings with automatic centering and convex spherical multi spring compensation sealing structure
detail
HS-G type rotary joint is an industrial dynamic sealing device with bi-directional flow, fixed inner pipe, and threaded connection, designed to efficiently transport fluids (water, air, saline water, etc.) from fixed pipes to rotating rollers and reflux
detail
The elbow rotary joint is a pipeline connection device that combines flow direction change (elbow function) and relative rotation sealing transmission (rotary joint function), used to transport fluid from a fixed pipeline without leakage to the equipment end that needs to swing or rotate.
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.
