Abstract
A linear motion rolling contact guide unit includes a rail, a slider assembly and a plurality of rolling members interposed between the rail and the slider assembly. The slider assembly includes a pair of lower and upper sub-assemblies. The lower sub-assembly is slidably mounted on the rail and the upper sub-assembly is mounted on the lower sub-assembly such that it may move transversely relative to the lower sub-assembly over a limited distance. A low friction intermediate member is provided at a first location in a gap between the opposed surfaces of the upper and lower sub-assemblies so as to provide an enhanced sliding characteristic therebetween. A squeeze film damper mechanism is provided at a second location in the gap between the upper and lower sub-assemblies for damping and/or absorbing undesired motion.
