  1. Add 'EX' or 'GR' to reference for expansion type or fixed type respectively, e.g.
    bearing: 01E B 215 EX
    cartridge: 01 C 04 EX
    bearing,cartridge and seals: 01E BC 215 EX AT
    complete unit: 01E BCP 215 EX AT

    Pillow blocks are common between expansion and fixed type units
     
  2. Total available axial movement given. Maximum offset from centerline half this amount. 'Usual' axial movement denotes maximum recommended range of running positions of EX bearing for optimum performance. 'Maximum' axial movement denotes available movement before bearing strikes inside of standard Cooper cartridge.
     
  3. Maximum fillet radii of abutments:
    inner race: 3/64"
    outer race: 1/64"
