Fitting the clamping finger
Please note
The clamping finger set from Festo matches optimally the CLR−... and does not
require any air restriction.
S Note that if user−made clamping fingers are used, the mass moment of inertia
must be calculated.
A higher mass moment of inertia than that specified for the clamping finger
set from Festo requires a reduction in the stroke time of the CLR−... by the use
of one−way flow control valves.
The dimensions of the cone and the diagrams for determining the stroke time
as a factor of the mass moment of inertia can be found in the Festo cata
logue.
Please note
When the fastening screw of the clamping finger clamps and releases, sudden
unexpected torques (if the spanner slips / if a tight screw is loosened) can,
under circumstances, damage the guide sleeve in the cylinder.
S When fitting or removing the clamping finger, always use a vice for fixing.
In this way you can avoid damage caused by sudden torsion torques which
occur during fitting.
Treat the clamping finger set with great
S
care.
The following loadings are not permitted:
heavy loads with a long lever arm
sudden knocks
high torques (especially on the guide
sleeve).
