Total duration for all tightening steps
The total duration of all tightening steps can be determined by the expected maximum angle of turn and
the selected speed of each tightening step. Thanks to the high acceleration when starting and stopping
the spindles, these times need not be taken into account.
The total duration of all tightening steps or minimum cycle time is calculated by the sum of the individual
times:
t
cycle
= t
tight
+ t
pre
+ t
end
(for a three-stage tightening process)

Compatibility with foreign substances
All tightening system components from Rexroth are developed and tested in accordance with the latest
state-of-the-art.
As it is impossible to follow the continuous development of all the substances with which our tightening
system components may come into contact (e.g. lubricants for machine tools), reactions to the materials
used by us cannot be excluded in every case.
For this reason, you must perform a compatibility test for all new lubricants, detergents, etc. with our hous-
ing materials prior to use.
