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.

Seal arrangement for a load-carrying bearing, particularly for coordinate measuring devices

The invention is directed to a coordinate measuring apparatus in bridge configuration wherein a bridge spanning the measuring pad is guided on two guides laterally of the measuring pad. To avoid measurement errors, which are caused by different warming of the coordinate measuring apparatus, the guides are mounted on the support rods which have a low thermal coefficient of expansion and the support rods are arranged in a support structure.
