ROTARY UNION
ROTODISK SW – Rotary Union with axial mechanical seal
Your benefits
Easy installation even in confined spaces
ROTODISK SW has been specifically designed for radial coolant supply to milling heads. Realized in an extremely compact cartridge design, the radial single-channel rotary union will fit even into the tightest spaces.
Unsurpassed service life
The sealing elements relieved of hydrostatic load are manufactured from resilient, low-friction material for minimized frictional torque and extraordinary service life.
Suitable for any media
ROTODISK SW units are available in individually adjusted variants. For example as complete rotary unions for multi-channel applications and different media.
