The guide carriage ( ) comprises at least one endless rolling element channel ( ) for the rolling elements ( ). The rolling element channel ( ) comprises a load-bearing channel ( ) for load-bearing rolling elements ( ), a return channel ( ) for returning rolling elements ( ) and deflecting channels ( ) arranged at both ends of the load-bearing channel ( ) and the return channel ( ), which deflecting channels ( ) connect the load-bearing channel ( ) and the return channel ( ) endlessly to each other and deflect the rolling elements ( ) out of the return channel ( ) into the load-bearing channel ( ), and vice versa. The rolling elements ( ) are received in pockets ( ) of a cage strip ( ) having at least two free ends ( ). The cage strip ( ) comprises spacers ( ) that define the cage pockets ( ) and are arranged, as seen in circulating direction, between successive rolling elements ( ). The cage strip ( ) further comprises cage belts ( ) arranged on both sides of the rolling element row to connect the spacers ( ) to one another. The cage belts ( ) are received in guide channels ( ) of the rolling element channel ( ) for guiding the cage strip ( ) in the rolling element channel ( ). Adjacent free ends ( ) of the cage strip ( ) comprise movable legs ( ) that are arranged substantially crosswise to the cage strip ( ), and opposing end surfaces of the legs ( ) are configured as contact surfaces ( ) for the legs ( ) with each other.
