Multi-passage rotary joints without leakage recirculation
GV series multiple-passage rotary joints are designed to supply rotating or swinging fixtures (work-holders) with pressurized oil.
These rotary joints can be coupled when pressurized and must be installed in the centre of rotation. A low torque is required for starting the rotating movement. GV multi-passage rotary joints do not require leakage lines as no internal oil leakage occurs.
To ensure a long service life of the internal seals, make sure to connect the rotary joint to all hydraulic supply ports. The operating temperature should not exceed 60°C. In addition, we recommend using oil filters with a 10 micron filter mesh.
GV rotary joints are made of heat-treated and ground high-quality steel. They are only suited for operation with hydraulic fluids, cooling lubricants must not be used.
