● Smooth motion

Since its stroke is finite, the balls do not recirculate and travel smoothly even under a preload.  In addition, fluctuation of the rolling resistance is minimum.  Therefore, the product is optimal in places where a short stroke and smooth motion are required.

● High rigidity

Since model EPF adopts a DB structure in 4 rows of circular arc grooves, it has a high rigidity especially against a moment load in the Mc direction.  Therefore, the product is optimal for use in places where an Mc moment is applied to a single axis.
