Note1) The maximum length under “Length * ” indicates the standard maximum length of an LM rail. (See A1-378 .)
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.
Note2) For models SR15 and 25, two types of rails with diff erent mounting hole dimensions are off ered (see Table1 ).
When, replacing this model with model SSR, pay attention to the mounting hole dimension of the LM rail.
Contact THK for details.
Note3) 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.
