ABSTRACT:
A shaft is borne in a standard by an intermediate member and a supporting bearing so that the shaft may follow without constraint lateral shifts of the supporting bearing by tilts about a plurality of small angles located in different planes. This effect is achieved by providing one of two guiding rings for the shaft within the intermediate member with two small sliding projections. These projections may be vertically arranged on a diameter of the intermediate member, which in turn is mounted to the standard by two small seat-engaging surfaces which are horizontally arranged on a diameter of the intermediate member. The apparatus is preferably used with shaft angle encoders for theodolites.
