Precision angular contact bearings (screw drive, spindle, e-axis) configuration knowledge

Bearing the common sense

  Bearing the number of code groups
  / D - two sets of bearings
  / T - three sets of bearings
  / Q - four sets of bearings
  / P - five sets of bearings
  / S - six sets of bearings

  Bearing arrangement of the group code

  B - back to back
  F - Face to face
  T - Series
  BT - back to back and connected in series
  FT - face to face and in series
  BC - back to back in pairs in series
  FC - face in pairs in series

  For example:
  760206TN/DB installed in pairs back to back
  760206TN/DF installed in pairs face to face
  760206TN/DT installed in series in pairs
  760206TN/TBT three configurations, two series and a set of back to back
  760206TN/TFT three configurations, two series and a face to face
  760206TN/TT three configurations, the series
  760206TN/QBC four configurations, paired back to back in series
  760206TN/QFC four configurations, paired series of face to face
  760206TN/QT four configurations, the series
  760206TN/QBC four configurations, and a set of three back to back series
  760206TN/QFT four configurations, three series and a face to face
