  • two layers of the steel sheet are at least partially adjacent to each other, so that increased forces can be absorbed.
  • the rollers rolling on the rail are adapted to the contour of the raceway, whereby usually no linear contact surface, but only one contact point has to remove the weight loads on the roller. This leads to a high pressure load, which can lead to deformation.
  • the leadership of the roller in the axial direction is not accurate.
  • the at least one track on the guide rail is concave or convex up or down in cross section, the roller contacting the curved track at two spaced apart points on opposite sides of a median plane of the track are arranged.
  • the mid-plane of the track may be a plane passing through the highest point or a concave downward-curved track through the lowest point, so that on both sides of the median plane a portion of the guide rail on a convexly upwardly curved track Running track is arranged.
  • the center plane may be a mirror plane with respect to the track when the track is mirror-symmetrical on both sides of the median plane. Due to the two spaced contact points, the contact pressure at the individual points is reduced.
  • the two contact points allow centering of the roller and thus improve the guidance of the roller in the axial direction.

  • a good centering of the roller is achieved on the track.
