A guiding device ( 30 ) for an elevator system ( 20 ) facilitates guiding a cab ( 22 ) along guide rails ( 24 ). The guiding device ( 30 ) includes a roller mount ( 34 ) that supports rollers ( 36 ) such that the rollers remain a fixed distance from each other. A biasing member ( 44 ) urges the mount ( 34 ) in a direction that maintains contact between the guide rail ( 24 ) and the rollers ( 36 ) and facilitates centering the guiding device ( 30 ) and the cab ( 22 ) relative to the guide rails ( 24 ).
