The external axial load on a preloaded bearing set or double direction bearing causing one ball set to become completely unloaded is called the lifting force (→ Influence of an external load on preloaded bearing sets). The lifting force for sets of single direction bearings arranged back-to-back or face-to-face and double direction bearings can be estimated using
Ka1 = 2,83 F0
|F0||=||preload on bearings before external axial load is applied

– double direction bearings → product table
