SELF-ALIGNING SYSTEM
The combined use of “fixed” rollers type RT and RCS with floating
rollers type RTL and RAS allows to obtain a selfaligning system, in
fact, floating rollers, where the bearing can slide axially on the stud, C
allow to recover any alignment error due to an inaccurate mounting
or deformations.

HORIZONTAL MISALIGNMENT DX
In case of horizontal misalignment Dx between mounting surfaces, you
can use on one side NT (LS) guides with carriages type RT(RCS) and,
on the opposite parallel side, NT (LS) guides with floating carriages
type RTL (RAS) that allow an axial misalignment Dx and RTL allow an

allow rotation of both carriages; for this reason carriages type RTY

(RYS) are equipped with “fixed” rollers RT (RCS), in contact with a
sliding track, and eccentric floating rollers (RASR and RTL) in contact
with the opposite raceway. On the parallel guide, a carriage with only
floating rollers type RTL (RAS) must be mounted.
