Advantge and application scope
As the traditional work-craft has some grudge between bushing with posts, and the coefficient of friction is larger. Now we have changed the work-ways to steel-ball directly face to face guide bushing, so the precision is improved. It composes of both active roll and lower friction coefficient, now they have been widely used in punching machine, die machine, high precision machine which need rotation and vertical motion.
