ABSTRACT:
Device for load measurement in roller bearings whereby the measurement is carried out by sensors arranged to measure forces applied on a bearing, and which communicates with circuitry for recording, processing and evaluation of signals emitted from the sensors, which are representative of the bearing load. At least one roller body (4a, 4b) per roller body row is provided with at least one bore (7) in which is provided at least one sensor (8), as well as circuitry (9, 10) for amplification and transmission of signals emitted from said sensor to a receiver (11) provided at the non-rotating bearing ring of the bearing. From the receiver, these signals are conducted further to external circuitry for signal processing, and so on.
