Dimensional drawing/Dimensional table
- Note) The M in the model number symbol indicates that the LM block, LM rail and balls are made of stainless steel. The stainless steel provides excellent corrosion and environmental resistance.
- Note) Static permissible moment * : Static permissible moment value with 1 LM block

- Note) While the cage used to hold the balls is designed tooperate extremely precisely, factors such as impactsor inertial moment or drive vibration from the machinecan cause cage distortion. If using the EPF LM guide in the following conditions,contact THK. ･ Vertical Orientation ･ Under a large moment load ･ Butting the guide’s external stopper with the table ･ For applications involving high acceleration/deceleration If cage distortion occurs, the cage must be forciblyrestored to its original shape. Table 1 shows the required slip resistance in this event. Set the thrust so that it is no less than the maximum value shown in the table.
Model number coding
(*1)See Accuracy symbol
- Note) This model number indicates that a single-rail unit constitutes one set.
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.
