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,
• 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.
