Bearing Monitoring

The bearing dimensions are used by the FactoryTalk Analytics GuardianAI algorithm to provide first principle failure mode recommendations. The failure modes included with the bearing dimensions are Ball Bearing Fault, Inner Race Bearing Fault, Outer Race Bearing Fault, and Bearing Cage Fault. If the values are left empty, FactoryTalk Analytics GuardianAI will not include those fault modes in the first principle recommendations when a deviation from normal is detected.
  • Inner Race Multiplier:
    [decimal number input] - BPFI (Ball Pass Frequency Inner) or inner race failing frequency. Corresponds physically to the number of balls or rollers that pass through a given point of the inner track each time the shaft makes a complete turn.
  • Outer Race Multiplier:
    [decimal number input] - BPFO (Ball Pass Frequency Outer) or outer race failing frequency. Corresponds physically to the number of balls or rollers that pass through a given point of the outer race each time the shaft makes a complete turn.
  • Rolling Element Multiplier
    : [decimal number input] - BSF (Ball Spin Frequency) or rolling element failing frequency. Corresponds physically to the number of turns that a bearing ball or roller makes each time the shaft makes a complete turn.
  • Cage Multiplier
    : [decimal number input] - FTF (Fundamental Train Frequency) or Cage failing frequency. Corresponds physically to the number of turns that make the bearing cage each time the shaft makes a complete turn.
Bearing Overview
NOTE: Rockwell Automation will be making an Excel database file available on Seismic of over 7000 bearings from common bearing manufacturers and models.
