Double row angular contact ball bearings
SKF double row angular contact ball bearings correspond in design to two single row angular contact ball bearings arranged back-to-back, 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.
The standard assortment of SKF double row angular contact ball bearings comprises bearings in the 32 A, 33 A and 33 D series. Matrix 1 provides an overview of the standard assortment. For information about other double row angular contact ball bearings.
SKF produces 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 (fig 1)
  • sealed bearings (fig 2)
  • bearings with a two-piece inner ring (fig 3)
  • large bearings for heavy engineering applications with two-piece inner or outer ring
Bearings in the 52 and 53 series, in accordance with ABMA standards, are no longer available from SKF and have been replaced with 32 and 33 series bearings in accordance with ISO. With the exception of size 3200, 32 and 33 series  bearings are dimensionally interchangeable with bearings in the 52 and 53 series. Size 3200 has a width of 14 mm instead of 14,3 mm.
