Achieving a smooth movement with minimal rolling variation.
The ball is held in a cage with a spherical ball holder, and the ball rolls on the rolling surface of the four-row circular arc groove of the precision ground LM rail and LM block.

basic information
● Smooth Movement Due to the limited stroke, there is no circulation of the ball, and even when preloaded, it moves smoothly. Additionally, the variation in rolling resistance is minimal, making it ideal for areas where smooth movement is required with short strokes. ● High Rigidity The EPF type adopts a DB structure with a 4-groove circular arc groove, providing high rigidity, especially against moments in the Mc direction. Therefore, it is optimal for use in locations where the Mc moment acts on a single axis. ● Miniature Type It is compatible with the mounting dimensions of the miniature LM guide RSR-N type, allowing for replacement. ● Four-Way Equal Load Each row of balls is arranged at a contact angle of 45° to ensure the same rated load in all four directions (radial, reverse radial, and lateral) acting on the LM block, enabling use in any orientation and a wide range of applications.
