The details of this product are exquisitely processed, ensuring smooth and burr free quality. The product layout is reasonable and the structure is simple. The product structure has been continuously improved and innovated by R&D personnel, resulting in better product quality and longer lifespan;
Using silicon carbide+graphite+sealing+pressure resistant high-speed parts for rotating lubrication, the steering is flexible.
The 57000-094 095 rotary joint is a series of products suitable for cooling design. It has the characteristics of small volume, light weight, and small friction torque. It adopts a balanced seal, and the friction group selects different combinations of impregnated graphite, bronze, carbon tungsten, and silicon carbide according to the medium environment. It can resist the influence of impurities such as rust, scale, and broken nitrate on the sealing surface. Our seals are completed on CNC machine tools and grinding machines, with a mirror like surface and good sealing performance.

Product Introduction
The H-type rotary joint, also known as the water copper rotary joint, is supported by two imported NSK and SKF high-speed tight bearings. It is easy to install and flexible to use, and can meet various complex connection requirements. The main components include the joint body (shell and hollow shaft), seals, seal compensation components, and connecting fasteners. The joint body is the main part of the joint, which is usually precision cast from high-strength metal (H62 alloy copper) material and can withstand high pressure and high temperature environments. Seals are important components used to prevent fluid leakage. They are usually made of wear-resistant and high-temperature resistant materials, which can maintain good sealing performance under high-speed rotation. The standard type uses high-density carbon graphite sealing rings, the high-temperature type uses antimony impregnated carbon graphite sealing rings, the high-speed type uses silicon carbide (ceramic) sealing rings, and the wear-resistant type uses tungsten carbide (hard alloy) sealing rings; All products in the series are equipped with 631 stainless steel compensating springs imported from Japan, which have the characteristics of high temperature resistance, corrosion resistance, and good mechanical performance; The connecting fastener is a component used to fix the joint body. It is usually machined with a hollow shaft made of stainless steel or other corrosion-resistant materials, and is equipped with various national standard threads and half ring quick change flanges, which can ensure the stability and durability of the joint.
The H-type rotary joint has a wide range of applications and can be used in various types of mechanical equipment, including hydraulic systems, pneumatic systems, cooling systems, etc. In addition, it can also be used for some special equipment such as compressors, pump stations, valves, etc. Whether in industrial production or daily life, the figure of H-type rotary joints can be seen.
