The LEJS63-M is a variation of the LEJS High Rigidity Slider. This variation includes internal intermediate ball screw supports. The supports travel with the slider, holding the ball screw and limiting bouncing and vibration. The resulting benefit is the possibility of longer strokes, maximum speed at any stroke, and the positioning repeatability typical of a ball screw.
