Types of Rotary Joints
 

Single passage rotary union: This is the most basic type of rotary union, providing a single flow passage for transferring fluids from a stationary pipe to a rotating pipe or vice versa. It allows for the transfer of a single fluid, such as air, water, hydraulic fluid, or oil.

 

Multi-passage rotary union: Unlike single passage rotary unions, multi-passage unions provide multiple flow passages, allowing for the transfer of multiple fluids simultaneously or individually. They are used in applications where there are request to transfer different media or where separate circuits need to be maintained.

 

High-speed rotary union: These types of rotary unions are designed to handle high rotational speeds while maintaining a reliable and leak-free connection. They are commonly used in applications such as high-speed machining centers, spindle applications, and rotary index tables.

 

High-pressure rotary union: High-pressure rotary unions are specifically designed to handle fluid pressures above the normal range. They are built with robust materials and seals to ensure the integrity of the connection under high-pressure conditions.

 

High-temperature rotary union: These rotary unions are designed to withstand elevated temperatures. They incorporate special materials, seals, and cooling mechanisms to prevent overheating and maintain the efficiency of the fluid transfer.
