Friction free Rotary union

 These Friction free rotary unions, are specially developed for long life operation with high speed rotation.

 Sealing is achieved by a reduced clearance between a tube in rotation inside a stationary hole.

Advantages of this patented principle:

  • No friction = No wear, no maintenance
  • Long  life time
  • Reduced driving torque
  • Can be used at high rotation speed
  • No need for lubrication
