The first feature is the large moment load. The THK LM
guide is used with two rails to withstand high moment
load. The second feature is ample options. Full stroke
adjustment (one or both sides), with cable bearer
(horizontal or vertical), and other options to match piping
port positions, etc., is selectable.
The X axis module sensor is installed on the T groove on
the front cover, so the distance with the magnet on the
slider is limited and a reed switch cannot be used. T2 or
T3 cylinder switch can be installed. When using a PLC
that may have leakage current, use the T3 (leakage
With the standard, the stroke can be reduced up to 15 mm
each from left and right. If larger stroke adjustment is
required, select full stroke adjustment. Note that the
stroke cannot be increased past the standard stroke with

Select the LCY (NHS-L) for high accuracy and light load.
Select the LCS (NHS-C) for high accuracy and medium load.
Select the HRL (NHS-H) for medium accuracy and high load.
Select the STL (NHS-S) for low accuracy and low cost.
Position locking is provided with all models as an option,
Consult with CKD as this may be possible in some cases.

When Darwin was a student atCambridge, he was interested less in books and laboratories than in mucking about in ponds and pokingat dead logs. During his three years at the university, from 1828 to 1831, he attended precisely onecourse of lectures in the natural sciences, bota
