Product introduction
The rotary union for coolant is a mechanical device specially used for transmitting coolant, which is mainly used in rotating equipment that needs cooling. Its core function is to establish a sealed liquid channel between the stationary part and the rotating part, allowing the coolant to flow continuously when the equipment rotates.

Product features
Strong Sealing
The rotary union for coolant adopts an annular sealing ring structure, which can always maintain close contact with the shaft during the rotation process, and the matching accuracy with the shaft is 0.01mm, which can effectively prevent the leakage of the medium.
Good Pressure Resistance
The shell of the rotary joint is formed by CNC turning after integral forging. The weld-free structure can avoid the weak strength area caused by stress concentration in the welding part, greatly improving the overall pressure bearing capacity. Therefore, the maximum pressure of the product is up to 4.0MPa, which is suitable for most industrial medium and high pressure fluid systems.
Two Connection Methods
The rotary joint provides two common connection methods: threaded and flanged. The threaded connection is suitable for occasions with limited space; the flange connection has better stability. Both connection methods meet industry standards to ensure compatibility with most existing equipment.
