Standard single row crossed rollers slewing rings with external gear with an average raceway diameter from 307 to 5,500 mm
Linear contact between the roller and the raceway limits contact pressure and therefore increases service life. The crossed rollers arrangement allows axial and radial loads to be accepted, while ensuring good rigidity of the assembly.
It should be noted that the rigidity of the supports is very important in order to guarantee proper operation of the crossed rollers slewing rings.
