Clamping Discs

The Clamping Discs operate in the same way as the Clamping Strips and are very effective in locking Slideways, pallets and supports.The essential advantage of this Clamping Disc is its compact design. Hydraulic pressure up to 250 bar allows a clamping force of up to 8.000 N per Clamping Disc with an efficiency of 99%.

Method of Operation
When pressure is applied, the KOSTYRKA® Clamping Discs are forced out of their housing like a piston, place themselves onto the component to be clamped and clamp it firmly, as determined by the amount of the oil pressure. After the oil pressure has completely released, the Clamping Discs ”spring” back approximately 0.01 mm (0.0004 in.), without the seal moving in the location hole. This feature eliminates wear and tear on the seals and assures long and trouble-free operation.

Fitting Regulations

For all sizes of Clamping Discs in an unmounted state the unit height H amounts to 8 mm (0.315 in.). Since the high-pressure seal is considerably compressed during mounting, the height increases to a maximum value of 9 mm (0.354 in.).
Therefore the depth of the location hole for all clamping disc dimensions must be a minimum of 10 mm (0.393 in.).
The surface roughness of the location hole may not exceed Rmax = 6-10 µm (microns) (Ra < 1.6 µm). It is imperative that machining grooves, particularly longitudinal grooves in the jacket surface are avoided!
The diameter of the location hole is to be of DIN ISO tolerance H7 fitting. If several Clamping Discs are connected by a single longitudinal hole, a vent hole should be provided.

Figure 1
Shows the classical method of using Clamping Discs. These are set into a lower locking bar and joined together by means of a continuous longitudinal hole.

Figure 2
Clamping Discs can be installed directly into a V-ledge design.

Figure 3
In order to avoid long connecting holes, the oil chambers of the Clamping Discs can be joined together with random holes drilled at a slant.

Figure 4
This shows oil connection holes, which lead to the oil chambers from the front end or from the side.
