Abstract

A meter bearing with a recess located at the periphery of at least one of the bearing rings. Expansion-measuring strips are disposed in the recess and conducting paths and electronic modules are arranged on a supporting material and evaluate and transmit the output signals of the expansion-measuring strips. The expansion-measuring strips are connected to the electrical conducting paths which extend to the electronic modules. In order to reduce the space required for such a measuring and evaluation system in a meter bearing, the expansion-measuring strips are placed below and/or above the radial plane of the supporting material and of the conductor paths and electronic modules located thereupon.
