Coupling Elements without Coupling Stroke

Coupling Elements without Coupling Stroke - ROEMHELD F9.461

• Max. operating pressure 200 bar
• Threaded-body type, ND 4
• Nominal diameter: ND 4
• Max. flow rate: 8 l/min
• Max. coupling force 4.0
• Positioning tolerance, axial: +0.05 mm
• Positioning tolerance, radial: 2 mm

Advantages:

• Radial misalignment of 2 mm is possible
• No coupling stroke required
• No protruding contours
• Compact dimensions

Application:

Coupling elements are used on machine tools with pallet changing systems in order to transmit hydraulic oil and compressed air from the machine tool table to the fixture.

Description:

These automatically closing couplings have a flat surface and do not have protruding elements for sealing. Therefore exact positioning is not required and a radial positioning misalignment of up to 2 mm is admitted. Cleaning of the coupling surfaces is easily possible due to the flat surfaces. Because of the omitted active axial coupling stroke completely new solutions for the coupling motion can be realised.

Coupling versions:

Version S

This coupling is equipped with a standard pressure spring. Therefore this version is particularly suitable for double-acting hydraulic cylinders.

Version L

This coupling is equipped with a pressurereduced pressure spring. Thereby the minimum opening pressure and the closing pressure are reduced. This version is particularly suitable for single-acting cylinders as well as for pneumatic applications with some restrictions.
