A roller carriage for displaceable linear guidance in a longitudinal direction on a rail element is disclosed. The roller carriage includes a carrier, a first roller or pair, a second roller or pair, and roller or pair. Every one of the first roller or pair, the second roller or pair, and the third roller or pair is 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 roller or pair, the second roller or pair, and the third roller or pair are disposed on the roller carriage such that the first roller or pair can be brought into engagement with a first track of the rail element and the second roller or pair and the third roller or pair can be brought into engagement with a second track of the rail element. One of the first roller or pair, the second roller or pair, and the third roller or pair is mounted such that it can move in a transverse direction perpendicular to the longitudinal direction relative to the carrier, and wherein the movably mounted roller is resiliently pretensioned in transverse direction by a first spring element.
