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)
- ** 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 Calculating the Equivalent Load to calculate the load rating for loads in the reverse radial direction or lateral direction.
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.
