3311A SKF Double Row Angular Contact Ball Bearing
Angular contact ball bearings have inner and outer ring raceways that are displaced relative to each other in the direction of the bearing axis. This means that these bearings are designed to accommodate both radial and axial loads. Double row angular contact ball bearings can accommodate radial and axial loads acting in both directions. The axial load carrying capacity of angular contact bearings increases as the contact angle increases. Double row angular contact ball bearings have a design corresponding to two single row bearings arranged back-to-back but occupy less space.
