A roller guide for use with sliding elevator doors may include elements for effecting quieter sliding door running by reducing noise associated with the rollers running along the roller guide. The roller guide may by formed by a convex running surface made from a hose-like covering of sheet metal producing a spring effect. The hose-like covering may be dimensioned to utilize the spring effect within an elastic range or limit of the sheet metal, with the optimum spring effect occurring when a radius of the rail running surface is slightly less than a radius of a running surface. An elastic material, to dampen running noise, may be inserted between the hose-like covering and a carrier section. The carrier section may also include spaces for clamping respective ends of the hose-like covering.
