Sealing disc for sealable ER clamping nut ER20 - Ø 7.5

Application:
Use in sealable ER clamping nuts. For sealing the collet slots.
Technical Design:
The sealing discs are available in steps of 0.5 mm. This means, the discs can cover a range of 0.4 mm from normal size shank down to smaller diameters. For example, to clamp a drill of dia. 5.7 a disc of the size 6 mm will be used. Please note! For high pressure of 100 bar, the size of the shank has to be the same as the nominal size of the disc.
