Abstract
A linear motion guide assembly is disclosed which employs an extruded U-shaped aluminum channel with inserted hardened steel races. A linear slider having recirculating roller element bearings which is slidably mounted upon the extruded track. The load bearing races of the recirculating bearings are opposed to in a spaced parallel relation to the insertable bearing races of the track. The track has linearly extending structures substantially parallel to the track races the structure being of substantially decreased stiffness so forming elastic hinges which supply an elastic pre-load between the track and the linear slider and wherein the lower modulus of the housing and the hinged structure allow significant deflection of the housing without excessively pre-loading the bearings.
