Double Row Ball Bearing

Features


  • Due to their internal design, angular contact ball bearings can withstand high radial-axial loads and reach high speeds. They are asymmetrical for manufacturing reasons and can withstand unidirectional axial loads only. Angular bearings are usually mounted in a group of two or more opposed preloaded units with rigid or elastic spacers. Typically, the inner and outer raceways and balls are made of chrome steel. Where operating conditions are severe, bearings may have ceramic balls creating a hybrid bearing.
  • Double Row Angular Contact ball bearings are available in two numerical series:
  • 5200 Series – Lighter load, higher speed, more/smaller balls per bore diameter.
  • 5300 Series – Heavier load, slower speed, fewer/larger balls per bore diameter.
  • Angular Contact Ball Bearing Series
  • ISO 18 Series - highest speed, lowest load bearings
  • ISO 19 Series - second highest speed, with the second lowest load bearings
  • ISO 10 Series - highest load, second lowest speed bearings
  • ISO 02 Series - highest load, lowest speed bearings

Double-Row Angular Contact Ball Bearings
This is basically a back-to-back mounting of two single-row angular contact ball bearings, but their inner and outer rings are each integrated into one. Axial loads in both directions can be sustained, and the capacity to sustain moments is good. This type is used as fixed-end bearings. Their cages are pressed steel.
