Model SSR-XW

 With this type, the LM block has a smaller width 

(W) and tapped holes.

 

Model SSR-XV

This type has the same cross-sectional shape 

as SSR-XW but has a shorter overall LM block 

length (L).

 

Model SSR-XTB

Since the LM block can be mounted from the 

bottom, this type is optimal for applications 

where through holes for mounting bolts cannot 

be drilled on the table.

 

 Model SSR-XSB

This type has the same cross-sectional shape 

as SSR-XTB but has a shorter overall LM block 

length (L).

Note

Note1) The maximum length under “Length * ” indicates the standard maximum length of an LM rail. (See A1-118 .) 

 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 ) ** 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) For models SSR15 and 25, two types of rails with diff erent mounting hole dimensions are off ered (see Table1 ).

 When, replacing this model with model SR, 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.
