Double row angular contact ball bearing with snap ring and split inner ring
Double row angular contact ball bearings, with snap ring and split inner ring, correspond to a pair of single row angular contact ball bearings in a back-to-back arrangement. The snap ring, fitted in an annular groove in the outer ring, facilitates axial location of the bearings within their housings. The split inner ring enables incorporation of more balls, resulting in higher load carrying capacity.

  • Snap ring facilitates axial location within housing
  • Accommodate very high axial loads in both directions, radial loads, and tilting moments
  • Suitable where a stiff bearing arrangement is required
  • Require less axial space than equivalent pair of single row angular contact ball bearings
