Abstract
A linear motion rolling contact guide unit includes a rail having a horizontally extending wing section, a slider slidably mounted on the rail and a plurality of rollers interposed between the top surface of the rail and the slider so as to allow a shift in position in a lateral direction between the rail and the slider as the slider moves along the rail. A first slide member is fixedly attached to the slider to define a first squeeze film damper between the top surface of the rail and the first slide member. A second slide member is fixedly attached to the slider to define a second squeeze film damper between the bottom surface of the wing section and the second slide member. Each of the first and second squeeze film dampers includes an oil film for damping or absorbing any undesired vibratory motion.
