DOUBLE DIRECTION ANGULAR CONTACT THRUST BALL BEARINGSFAG double direction angular contactthrust ball bearings were developedfor the machine tool industryand are manufactured exclusivelyas high-precision bearings.They accommodate axialloads in the main spindles of machinetools and exhibit the sameabutment dimensions as doublerow cylindrical roller bearings ofseries NN30 (page 94) that take upthe radial loads.External DimensionsDouble direction angular contactball bearings are mounted in combinationwith double row radialcylindrical roller bearings. Thenominal outside diameters of thetwo bearings are identical. This facilitatesthe machining of the housingbore. The tolerance for the outsidediameter of the angular contactthrust ball bearing has beendetermined in such a way that thebearings have a certain clearancein the housing bore.Bearing DesignThe double direction angular contactthrust ball bearings have acontact angle of 60° and are axiallypreloaded. This results in theirhigh axial load carrying capacityand rigidity.FAG · 102
