Double Row Angular Contact Ball Bearings

The double row arrangement of angular contact ball bearings is similar to the arrangement of two single row angular contact ball bearings put back-to-back, but requires less axial space. They can accommodate radial loads, axial loads in either direction and tilting moments.

The double row angular contact ball bearings are available in three different versions:

  • Open (default)
  • Closed with metal seals on both sides (2Z version)
  • Closed with rubber seals on both sides (2RS version)

The two closed versions are pre-lubricated with a high quality grease, while open ball bearings have to be lubricated externally. The 2Z version creates less friction than 2RS, but has worse sealing capabilities.
