Double row angular contact ball bearings correspond in design to two single row angular contact ball bearings but take up less axial space. They can accommodate radial loads as well as axial loads acting in both directions. They provide stiff bearing arrangements and are able to accommodate tilting moments.
Double row angular contact ball bearings in several designs depending on size and application. These are described in the following and include
|
– |
basic design bearings |
|
– |
sealed bearings |
|
– |
bearings with a two-piece inner ring |
|
– |
large bearings for heavy engineering applications with two-piece inner or outer ring |
