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
