Screw Connect Couplings : SP Series


Applications :

Ball Screw Coupling that use ball-in-groove retaining mechanisms, the separating forces are concentrated onto a relatively small area - point contact of the balls -which can cause Brinelling (indentation of the balls into the groove). Brinelling will lead to leakage and eventually seizure of the coupling. Screwed Couplings have a screw thread retaining mechanism that distributes the separating forces over a large surface area, thus eliminating Brinelling.

Advantages :

  • Screw thread retaining mechanism to eliminate brinelling
  • Connection and disconnection can be performed even with low residual hydraulic pressure in the line.
