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 to 

operate extremely precisely, factors such as impacts 

or inertial moment or drive vibration from the machine 

can 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 forcibly 

restored 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.
