LINEAR MOTION GUIDE APPARATUS IN TESTING APPARATUS

摘要

A linear motion guide device is provided to perform testing endurance of machine part and to reduce damage of a cylinder by guiding the liner motion to a substrate without the linear motion error of cylinder. A linear motion guide device comprises: a shockproof steel board(10) including a substrate(13) and cylinder(15); and a guide unit(30) installed between the substrate installed in the upper of the shockproof steel board and a cylinder in order to guide the linear motion of cylinder to the substrate. If error is generated on the straight movement direction of cylinder, the guide unit does the angular motion as much as the generated error and delivers the linear motion of cylinder to the substrate.
