Statically optimized hybrid roller bearing

A bearing for longitudinal movement along a cylindrical guide portion of a rail extending with a cylinder axis in a longitudinal direction, the bearing comprising:

• a housing having a passageway running through the housing along a longitudinal axis running in the longitudinal direction, the passageway forming a receiving channel for receiving the guide portion of the rail;
• and
• two rollers spaced apart in the longitudinal direction, each roller being rotatable in the housing about a roller axle running perpendicular to the longitudinal direction and each roller bounding the receiving channel with a running surface in a transverse direction extending perpendicular to the roller axle, and
• wherein the housing has, in the longitudinal direction between the rollers, a mounting channel running through the housing perpendicular to the longitudinal direction along a mounting axis for receiving a mounting peg which is rotatable about the mounting axis, and
• wherein a plurality of sliding elements is arranged in the passageway spaced apart from each other in the longitudinal direction, the sliding elements being longitudinally spaced apart relative to the rollers, said sliding elements each bounding the receiving channel perpendicular to the longitudinal direction.
