Claim 1:
2. A linear guideway assembly for contactless linear displacement of a movable rigid body relative to another rigid body along a linear displacement path (x), said linear guideway assembly comprising:
one, single rigid body formed as a single linear guideway defining said linear displacement path as well as
at least one movable rigid body formed as a product carrier being displaceable along said single linear guideway, wherein
the linear guideway assembly further comprises a group of multiple magnetic bearing assemblies for allowing contactless linear displacement of the at least one product carrier relative to the single, linear guideway, wherein
the group of magnetic bearing assemblies is mounted to the product carrier in such way that the group of magnetic bearing assemblies is arranged in constraining five degrees of freedom (y, z, θ, Φ and ψ) of the product carrier relative to the single, linear guideway, whilst allowing one, translational degree of freedom (x) of the product carrier along the single, linear guideway, wherein
the product carrier at least comprises a first longitudinal side and a second longitudinal side opposite from the first longitudinal side oriented in the direction of the linear displacement path (x), and wherein the product carrier is supported, guided and transported at its first longitudinal side along the linear displacement path (x) by means of the single, linear guideway, whereas the other, second opposite longitudinal side is unsupported and freely moving along the linear displacement path (x), and wherein the group of magnetic bearing assemblies, seen in the direction of the liner displacement path, is mounted at the first longitudinal side of the product carrier closest to the single, linear guideway,
wherein the single, linear pathway, seen in the translational direction (x) of the linear displacement path, is provided a first guidance recess present at the side of the linear pathway facing away from the product carrier, and a second guidance recess at the other side of the linear pathway facing towards the product carrier and wherein each magnetic bearing assembly at least in part is accommodated in one of said guidance recesses.
