Gap sealing oil cylinder matching rotary joint
Product Introduction
This multi-passage rotary joint is specially developed to match gap sealing hydraulic oil cylinders. It acts as the rotary transmission interface between the fixed oil circuit and rotating oil cylinder, realizing 360° continuous rotation while delivering hydraulic oil to each independent oil passage of the gap sealing cylinder.
Built with high-strength alloy housing and precision composite sealing components, the rotary joint features stable gap sealing performance. It can withstand high hydraulic pressure and maintain low leakage during long-duration rotary operation. Each flow channel is independent without cross-channel oil mixing, which fully matches the multi-chamber oil supply requirement of gap sealing cylinders.
Product Features
Rotating joint for vertical automatic fixture
Supported by two wide and high-precision bearings, the operation is smooth and the bearings do not require maintenance for life;
High speed and high-pressure sealing structure, no contact wear of sealing rings, ensuring long-term trouble free operation of the product;
Lower rotational torque;
Adopting a special product structure, there is no frictional heat generated during high-speed operation;
The rotational torque is not affected by working pressure and temperature;
The working range of the speed is wide, and it can reach up to 6500 RPM at high speeds;
Drain hole design to prevent leakage to the external environment;
Being able to tailor products to meet the needs of customers;

Important note:
The K series products adopt a gap sealing structure, and the discharge hole L must be connected to the return oil tank using an oil pipe during installation, and the return oil pipeline must not be blocked to form pressure;
2. There is mutual leakage in the internal channels, and attention should be paid to the compatibility of different fluids to prevent cross contamination;
3. High precision connectors should be used after filtering the working fluid, with a filtration accuracy of not less than 10 μ m;
4. The increase in temperature will reduce the viscosity of hydraulic oil, causing an increase in internal leakage. A cooling device is required during use;
5. The hydraulic system needs to have an automatic pressure regulator to compensate for pressure loss caused by internal leakage in the joints
