Abstract
In a linear motion slide unit, it is usable under a heavy load with high precision, or in a light load, an over-stroke amount can be made large. The linear motion slide unit comprises an elongated inner rail having high rigidity, a pair of outer rails attached to be reciprocally movable in an axial direction of the inner rail, and linear motion guides of endless track type structure disposed to be slidable with respect to the inner rail and fixed to the outer rails. A bearing body of the linear motion guide has also high rigidity, and accordingly, the balls mounted inside the endless track is applied with a large preload.
