Principal dimensions is 11.024х15.335х3.622 in. equal to 280х389.5х92 mm.
Open type bearing without sealing. Require little maintenance.
Contact angle is 32 °
Two-piont (normal) contact type.
Machined metal cage.
Metric series product.

Double row angular contact ball bearings with split inner ring suitable for radial and axial loads acting simultaneously, where the axial load and tilting moments acts in both direction.
The two-piece inner ring allow filling the bearing with a larger number of balls, with a larger contact angle, providing a high load carrying capacity, especially in the axial direction. In their design and operation correspond to a pair of single row angular contact ball bearings in a back-to-back arrangement (O-arrangement), while requiring less axial space. They can operate at high speeds and, depending on the variant, even very high speeds. Require less axial space than equivalent pair of single row angular contact ball bearings, suitable where a stiff bearing arrangement is required.
