1. A system for sensing rolling element loads in a rolling element bearing having a plurality of rolling elements disposed between an inner race and an outer race, comprising:

  • a plurality of sensors disposed about one of the inner race and the outer race of the bearing to output sensor data corresponding to detected loads caused by the rolling elements;

    a plurality of connecting members respectively connected to each of said plurality of sensors to transmit the sensor data; and

    a control unit to receive the sensor data from said plurality of connecting members, wherein said control unit calculates load components corresponding to each of the sensors in the rolling element bearing from the received sensor data and predicts bearing life from the calculated load components.
