Slewing bearings are applied commonly in the following devices inter alia: harbour cranes, traveling cranes, radar stations, machinery underground and an opencast mining, armaments industry, building machines, medical analysis devices, rotary kilns, manufacturing systems, a power engineering. A static limiting load curve of the slewing bearings describes ranges of the allowable loads, which the bearing can be safely carried for assumption by a manufacturer durability. The static carrying capacity of a slewing bearing describe the relationship between a tilting moment M and an axial force Fa for assumed a value of a radial force Fr. The article concerns problems related to catalo selection of rolling bearings which are loaded the large radial forces which may by differently directed in relation to a tilting moment's vector. Manufactures of the slewing bearings mostly does not present in product catalogs of a static limiting load curve, which have taken into account an action the radial forces. According to an INA company, the radial forces are reduced to determining an equivalent tilting moment and an equivalent axial force. In this work, the static limiting load curves have been determined based on the FEM models, the equations of contact mechanics for the ball and the bearing raceway. The models were performed by use the ADINA system. Juxtaposition of results obtained on a basis of method's INA company and own model have been presented in form the static limiting load curves. The object of the analysis was the one row ball slewing bearing, domestic production, which is used in excavator type F250H.
