500-4 Controlled rotary unions Nominal size 5, for single/double-acting clamping elements, pmax. 350 bar

Controlled rotary feedthroughs transfer hydraulic oil to rotary indexing tables. The construction is designed as a rotary valve. This allows several hydraulic devices to be supplied with pressurized oil at the same time and a loading and unloading station to be clamped or unclamped independently of this via directional control valves.

Info

The controlled rotating unions may only be operated with hydraulic oil. All levels must be connected to the pressure generator to ensure seal lubrication. Commissioning may only be carried out with the screw connection fitted. Controlled rotating unions should only be used for cyclic operation.

From an operating pressure of approx. 200 bar, we recommend installing a hydraulic accumulator with an accumulator safety device between the non-return valve and connection level A (continuous pressure range). The accumulator has the task of compensating for small leakage oil losses when the pressure is released in the loading and unloading station. It is recommended that only directional seat valves are used to control the rotary joints.

Special features:

  • Axial and radial connections in the piston
  • Standard variants and special variants available
  • Single-acting and double-acting available
  • Up to 10 stations possible
  • with 1 or 2 stations for loading/unloading
  • for separate or simultaneous control

Functional principle:

530-3 Rotating union diagram Application

The controlled rotary feedthroughs must be installed in such a way that no bending moment is exerted on the stationary or rotating component. It has proven to be a good idea to bolt the rotating housing to the connections to the clamping devices and only secure the stationary rotary piston against rotation (do not introduce any bearing forces). The line connection from the torque arm to the rotary piston should only be made via hose lines.
