1) The allocation of screw ends to the bearing assemblies is clearly defined by the version.
Separate technical dimensioning of the
permissible drive torque is absolutely
necessary.

Accessories
Overview
Rexroth offers an extensive range of accessories for ball screw assemblies.
These include Nut Housings, Pillow Block Units, bearings, Slotted Nuts, and Front Lube Units.
A reasonable ratio of the load capacities of the bearing and the ball screw drive should be taken into account when dimen-
sioning. Further information is provided in this section.

Accessories
Nut housing MGS
Steel nut housings MGS are designed
for FEM-E-S, FDM-E-S, FEP-E-S and
SEM-E-S nuts
In addition to bolting, the housings should
be locked in place by positive means
(e.g. two pins with a diameter equal to that
of the screws S2).
We recommend using screws with a
strength class of 8.8.
Tightening torque
see “Installation in the machine” on page 147
Reference edges are formed on both sides.
cc
If a Ball Screw Assembly with a
front lube unit is used, the front lube unit
may project beyond the housing. This
must be considered when calculating
the stroke.
