HYDROK – Technical data
Calculation example
[HYDROK size 42]
Calculation of the pressure [p] that has to be adjust-
ed, to get a certain max. traction axially.
Definition:
p

Comments
The diagram shows the influences of friction and
clamping diameter are included.
The maximum drawtube force [F
ax
] of the respective
adaptation clamping device must not be exceeded.
This value is given on the adaptation clamping de-
vice.
