Double row angular contact ball bearing with two-piece inner ring
Double row angular contact ball bearings, with two-piece inner ring, correspond to a pair of single row angular contact ball bearings in a back-to-back arrangement, while requiring less axial space than the equivalent pair of single row angular contact ball bearings. The two-piece inner ring enables incorporation of a larger number of balls, with a larger contact angle, providing a high load carrying capacity, especially in the axial direction.

  • Accommodate very high axial loads in both directions, radial loads, and tilting moments
  • Suitable where a stiff bearing arrangement is required
  • Separable design means outer ring with ball and cage assemblies can be mounted independently of the inner ring halves
