A roller carriage for displaceable linear guidance in a longitudinal direction on a rail element is disclosed. The roller carriage includes a carrier and a first, second, and third roller. The first, second, and third rollers are each mounted on the carrier such that each can rotate about a rotating axle. The rotating axles are substantially parallel to one another and the first, second, and third rollers are disposed on the roller carriage such that the first roller can be brought into engagement with a first track of the rail element and the second and third rollers can be brought into engagement with a second track of the rail element. The first roller is mounted such that it can move in a transverse direction perpendicular to the longitudinal direction relative to the carrier and is resiliently pretensioned in transverse direction by a first spring element.
