Double row angular contact ball bearing with wide and two-piece inner ring and relubrication feature

Double row angular contact ball bearing, with wide and two-piece inner ring and relubrication feature, correspond to a pair of single row angular contact ball bearings in a back-to-back arrangement.

The two-piece inner ring enables incorporation of more balls, resulting in higher load carrying capacity. The annular lubrication groove and holes in the outer ring facilitates relubication.

  • Wide, two-piece inner ring
  • Accommodate very high axial loads in both directions, radial loads, and tilting moments
  • Relubrication feature
  • Suitable where a stiff bearing arrangement is required
