Rotary union

The compact rotary unions are characterised by freedom from leakage at speeds up to 2100 rpm. The range of applications extends from low pressure to 210 bar medium pressure applications, where speeds of up to 1800 rpm are still possible. Couplings and variators are just two applications for our rotary unions.

In order to cater to the most diverse installation space situations, housings with various screw-in threads as well as hydraulic connections for axial and radial connection positions are available.

The rotary union with a maximum free passage of 2.5 mm diameter can also take on the function of a throttle valve. Different throttle cross-sections down to a diameter of 1.0mm can be selected for this purpose.
