The seal on our disc is greatly oversized, therefore during assembly it is strongly preloaded obtaining high adherence in its seat.
Because of this, the Clamping element can be moved slightly in either direction without creating friction with the wall of the seat.

When the oil pressure will act on the seal first, this will be slightly compressed, eliminating frictions, and will move until the disc will be placed on the surface to be locked.
The seal will assume its final position.

When unlocking the piece, simply release the pressure and the Clamping disc is spring returned of about 0.01 mm and comes away from the piece to be held.

It is important to point out that there is no friction during translation ensuring the longer life of the disc.

To ensure good working, avoid the formation of air bubbles in the pressurized oil circuit and purge any air in the circuit (if possible, create a vent hole in the most appropriate point). This feature, together with the frictionless nature of the seal, ensures the excellent expectancy and perfect efficiency of our disc.

Benefits

The designer who needs to spot lock moving components (like slides, cross-pieces, carriages, etc.) can use our discs to solve the problem in a safe and economic manner, requiring no maintenance.
Benefits:

  • Extremely compact.
    They simply require an hole having 10 ÷ 11 mm depth and H7 tolerance. The choice of the size can be directed to the smallest, thanks to the high pressure applied (up to 250 BAR), considerable clamping forces are obtained.
  • No wear due to friction between the disc and seal.
  • No leaking, the parts are waterproof.
  • Easy assembly with the special tool designed not to damage the seal during assembly.
