Note

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 

attached. 

 (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. 

＊＊ 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.
