Abstract

In a seal arrangement for a load-carrying bearing which is supported on a guide path provided on a carrying body and which is arranged so as to be movable along the length of the guide path, especially for coordinate measuring devices, the bearing is connected with a bearing cover. The bearing cover spans the carrying body at least on one side thereof and has a side portion which is bent toward its side, each side portion projecting into a labyrinth recess which is arranged on the associated side of the carrying body over the entire length of the guide path to form a labyrinth seal.
