A pull-out guide for furniture parts that can be moved in relation to each other includes at least two pull-out rails, each having at least one running surface, between which at least one first rolling element and at least one second rolling element are arranged. The rolling elements may be rotatably retained in at least one rolling-element cage. The at least one first rolling element and the at least one second rolling element of the rolling-element cage have an identical nominal diameter. The pull-out guide is distinguished in that at least one of the running surfaces has a free-running segment in which the at least one first rolling element is positioned in a retracted state of the pull-out guide, the running surfaces having a greater distance from each other inside the free-running segment than outside the free-running segment.
