Abstract
A linear rolling bearing comprises a guide carriage ( ) that is slidably supported through balls ( ) on a guide rail ( ). The balls ( ) are retained in two guide members ( ) that are detachably secured to a base body of the guide carriage ( ) covering the upper side of the guide rail ( ) and are arranged on longitudinal sides of the guide rail ( ) that comprise raceways ( ). For each endless circuit of balls, the guide members ( ) comprise one raceway ( ) for load-bearing balls ( ), one return channel ( ) for returning balls ( ) and two deflecting channels that connect the regions of the load-bearing and returning balls ( ) to each other. The guide members ( ) are made of an elastic material, and the return channel ( ) of each guide member ( ) comprises an opening ( ) that extends over its entire length and has a width that is smaller than the diameter of the inserted balls ( ). According to the invention, the opening ( ) also extends over the entire length of the respective deflecting channel, and the deflecting channels and the return channel ( ) comprise on their longitudinal sides opposite to the opening ( ), a closed bottom that cooperates in the guidance of the balls ( ).
