Accessories
Overview
Rexroth offers an extensive range of accessories for Planetary Screw Assemblies.
These include bearings and Slotted Nuts.
A reasonable ratio of the load capacities of the bearing and the Planetary Screw Assembly should be taken into account
when dimensioning. Further information is provided in this section.

Bearing assembly LAS
Fixed bearing with angular-con-
tact thrust ball bearing LGS
Double-thrust,
series LAS-E
The bearing assembly consists of:
--
angular-contact thrust ball bearing LGS
as per DIN 628 (not available as a sep-
arate part)
--
slotted nut NMA...
Separate technical dimensioning to
determine the limit values is absolutely
necessary for all attachments (e.g. pillow
block units, bearing assembly, etc.)
