Loading Graph – Slewing ring bearings, turntable bearings

In practice, most slewing bearings receive very little radial force (HP), which is usually less than 0.1Gp and can be ignored. To simplify the calculation, when selecting a standard size slewing bearing, the loading capacity charts are widely used to indie the loading capacity of the slewing bearings in many national or manufacturers’ standard.
