4. Caution for Operation
4. Caution for Operation
• When you tighten the nut onto the tip bracket threaded part, hold a wrench to width across flat
part of the tip bracket with the rod in the most retracted state. Also, avoid that the load is applied
to the inside whirl-stop as you tighten the nut.
As a general rule, it cannot be used to apply a torque to the rod tip. Statically acceptable values
and the rod tip maximum displacement angles (initial value reference) expected at that time are
shown below. When the reaction force against the pressing operation is the side-way force,
make sure it would not exceed the allowable load.
• Do not apply radial load and load moment to the rod. Only the radial direction load that aligns with
the rod axis can be applied.
In the case that radial load and load moment cannot be avoided, attach an external guide (such
as a linear guide) in order not to apply any load other than radial direction load to the rod.
When the gravity center of work is on the rod axis on vertical motions, vibration may still be
generated by the clearance of internal whirl-stop. Attachment of an external guide is
recommended to suppress such vibration.
• When connecting the rod to external guides, be careful on the parallelism of the guides to the
rod. When connecting and fixing the rod to external guides, be careful not to apply excess
side-way load to the rod because of the assembly variation.
