Circular arc grooves allow for high rigidity and high precision.

With a 4-row circular arc on each side for high rigidity and high precision (zero clearance)

・Improved moment resistance

・Table displacement amount reduced to 1/2

・Zero table clearance

Auto switches are mountable.

Allows for position detection of the table throughout the stroke

Same dimensions as the LEF/Complete mounting compatibility is ensured.

∗ Excludes size 16

The body bottom positioning pin holes have been standardized.

Magnet for adhesion of the dust seal band

Improved adhesion enhances the dustproof performance and reduces dust seal band blistering.
