Caged Roller LM Guide Ultra-high Rigidity Model SRG Models SRG-XLC/SRG-LC
The LM block has the same cross-sectional shape as model SRG-C, but has a longer overall LM block length (L) and a greater rated load.
Basic load rating(kN) : Basic dynamic load rating 34.2 to 601 / Basic static load rating 75 to 1170
Size :
25,30,35,45,55,65,85,100

Notes on dimensional table
Note1) The maximum length under "Length * " indicates the standard maximum length of an LM rail.(See Standard Length and Maximum Length of the LM Rail)
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 Conditions of the LM Guide, Lubricant: see Accessories for Lubrication)
- 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 LM Block Dimension (Dimension L) with LiCS Attached or LM Block Dimension (Dimension L) with QZ Attached)
The removing/mounting jig is not provided as standard. Contact THK before use.
** 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)H* ,T1*
If the mounting holes (4 holes) of the LM block are back spot-faced, these models can be mounted on the table from the top and the bottom as with the Model SRG-C.
The value in the parentheses represents a dimension if the mounting hole is back spot-faced. Contact THK for details.
- Note 3) The nine LM block mounting holes in parts (a) and (b) for SRG85LC are all through holes (fully threaded).
- Note 4) The six LM block mounting holes in part (a) for SRG100LC are through holes (fully threaded). The three LM block mounting holes in part (b) have an effective thread depth of 22 mm.
Note5) The basic dynamic load rating of the roller guide is a value based on a nominal life of 100 km. The conversion to basic dynamic load rating for a nominal life of 50 km can be obtained from the following equation.
| C50 | The basic dynamic load rating for a nominal load of 50 km |
|---|---|
| C | The basic dynamic load rating in the dimensional table |
Model number coding
(*1)See Contamination protection accessory symbol (*2)See Radial Clearance Standard (*3)See Accuracy Standard (*4)See Symbol for No. of rails used on the same plane
- Note) This model number indicates that a single-rail unit constitutes one set. (i.e., required number of sets when 2 rails are used in parallel is 2 at a minimum.) Those models equipped with QZ Lubricator cannot have a grease nipple. When desiring a grease nipple for a model attached with QZ, contact THK.

Notes on Ordering
[Order units]
Note that the number of items that constitute one set differs depending on the type of LM guide. Check the sample model number configurations and the accompanying notes.
