Double direction angular contact thrust ball bearing is made up of an upper component with a larger load carrying capacity and a lower smaller component locked to the machine. The two components are assembled together as a single unit. Typically characterized by a reduced height it is advised for combined loads when radial and axial loads act at the same time. It can also support (turn-over) tilting moments; only one bearing is, therefore, necessary to hold the rotating and the fastened components of the machine. Every single component of the bearing can be separately assembled making the assembling, the maintenance and the inspection procedures faster and easier.
