Rotors for long-stator linear motor systems, having a low-wear mounting arrangement

A long-stator linear motor system, comprising:

• a plurality of rotors, at least one rotor of the plurality of rotors comprising:
• at least two rollers for mounting the at least one rotor on parallel guide rails of the long-stator linear motor system, wherein at least one of a) at least one pair of rollers of the at least two rollers is rotatably mounted to at least one rotatable bolster of the rotor, or b) at least one roller of the at least one pair of rollers comprises a steering rotational axis with an integrated castor;
• wherein the at least one roller is mounted on a roller axle by means of a bolt, via at least one of an asymmetric bore or a sloping bore;
• and
• wherein the at least one roller further comprises a pendulum ring mounted on the bolt, the pendulum ring having an external ball or slide bearing;
• a transport path having at least two parallel guide rails on which the plurality of rotors are movably mounted, wherein a respective first roller of the pair of rollers of the at least one rotor is mounted on a first one of the at least two guide parallel rails and a respective second roller of the pair of rollers of the at least one rotor is mounted on a second one of the at least two parallel guide rails;
• wherein the transport path comprises at least one of a) at least one straight piece and at least one curved piece or b) curved pieces with different radii of curvature.
