For example in add-on units with rotational movements of up to 360°. TDG swivel joints minimise the extreme wear occurring in the hoses of the hydraulic system.
A patented Pressure Relief Unit guarantees a long service life and smooth running even in the event of pressure hammers.
NB: The TEMA Swivel joint has very low torque even at max. working pressure, due to a balanced spindle seal. The TEMA Swivel joint has been shock tested under pressure from 0 - 250 BAR.
