With this type, the LM block has a smaller width (W) and tapped holes. Used in places where the space for table width is limited.
The LM block has the same cross-sectional shape as models SVR/SVS-R, but has a longer overall LM block length (L) and a greater rated load.

Note1) The maximum length under “Length ＊ ” indicates the standard maximum length of an LM rail. (See A1-138 .)
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
For oil lubrication, be certain to let THK know the mounting orientation and where the LM block piping joint should be
(Mounting orientation: see A1-12 , Lubricant: see A24-2)
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) ＊＊ A pilot hole for side nipples, when a grease nipple for a model equipped with LaCS or QZ Lubricator is needed.
Pilot holes for side nipples are not drilled through for models other than those stated above.
For grease nipple mount machining, contact THK.
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.
