Claim:
Electromechanical motor, comprising: a rail to be moved; a bearing for said rail, said bearing being a sliding bearing, said bearing having a first rail contacting portion and a second rail contacting portion; and a driving member, being arranged to impose a mechanical driving force on said rail, said first rail contacting portion being in sliding contact with said rail and arranged for concurrently obstructing displacements of said rail in a first direction transverse to a main extension of said rail, and said second rail contacting portion being in sliding contact with said rail and arranged for concurrently obstructing displacements of said rail in said first direction transverse to said main extension of said rail, said second rail contacting portion having a contact area against said rail with an extension in a direction of said main extension of said rail that is smaller than a cross-section of said rail perpendicular to said main extension of said rail, whereby said contact area of said second rail contacting portion is in sliding contact with said rail and further arranged for concurrently allowing at least a minor rotation of said second rail contacting portion relative to said rail around an axis transverse to said main extension of said rail.
