Single direction angular contact thrust ball bearings
Single direction angular contact ball bearings (fig 1) are able to take up axial loads acting in one direction. They are of separable design, i.e. the washers and ball and cage assembly can be mounted individually. In the main application area for these bearings – rotary tables – two bearings are always adjusted against each other. The second bearing has to carry the weight of the drill when it is stationary and has a higher load load carrying capacity than the first bearing.
