Model SRS5WM
This model has a larger overall LM block length
(L), width (W), rated load and permissible moment than model SRS5M.
Model SRS-5WN
Overall LM block length (L) is greater than for
model SRS5WM; load rating and permissible
moment are higher as well.
Model SRS-WS
Has a longer overall LM block length (L), a
greater width and a larger rated load and permissible moment than SRS-S.
Model SRS-WM
Has a longer overall LM block length (L), a greater width and a larger rated load and permissible
moment than SRS-M
Model SRS-WN
Compared with Model SRS-WM, it has a longer
total LM block length (L) and a higher load rating and permissible moment.

Note
Note) Since stainless steel is used in the LM block, LM rail and balls, these models are highly resistant to corrosion and environment.
The SRS-G is equipped with uncaged, full-complement bearings.
Using a greasing hole other than for greasing may cause damage.
Note1) The maximum length under “Length ＊ ” indicates the standard maximum length of an LM rail. (See A1-164 .)
Static permissible moment ＊ 1 block: the static permissible moment with one LM block
Double blocks: static permissible moment when two LM blocks are in close contact with each other
Total block length L : The total block length L shown in the table is the length with the dust proof parts, code UU or SS.
If other contamination protection accessories or lubricant equipment are installed, the
total block length will increase.
(See A1-507 or A1-528)
For the SRS5WM and SRS5WN, the balls will fall out of the block if it is removed from the rail.
Note2) The basic load rating in the dimension table is for a load in the radial direction. Use Table7 on A1-60 to calculate
the load rating for loads in the reverse radial direction or lateral direction.
Note) Since stainless steel is used in the LM block, LM rail and balls, these models are highly resistant to corrosion and environment.
The SRS-G is equipped with uncaged, full-complement bearings.
For the SRS15WS/WM/WN, if a grease nipple is required, please specify upon ordering.
Using a greasing hole other than for greasing may cause damage.
Note) The maximum length under “Length ＊ ” indicates the standard maximum length of an LM rail. (See A1-164 .)
Static permissible moment ＊ 1 block: the static permissible moment with one LM block
