ABSTRACT:
A supporting and guide roller for pull-out guides for drawers comprises a roller body made of hard material, the shell surface of the roller body forming a first rolling surface, at least one circumferential groove being arranged in the area of the first rolling surface and being filled with an elastic material, which forms a second rolling surface when the roller is not under load and projects a certain amount over the first rolling surface. The second rolling surface is arranged in the area of a wider notch in the roller body extending in the peripheral direction of the roller. When the soft rolling surface is under load, the material of the soft rolling surface is displaced into the area of the notch.
