32207 Series 1

  • has conical rollers as rolling elements
  • suitable for high combined loads in one direction
  • it has also an axial load carrying capacity on both sides in the X- or O-arrangement in pairs
  • balanced ratio between radial and axial load capacity, size and weight
  • very good fixed bearing properties in one direction
  • manufacturers of bearings, such as FAG, KOYO, NSK, SKF, SNR, etc. assign different suffixes for their characteristics, for better orientation take note of t
