  • Slewing Ring bearing, Functions Bearing Fastening

    The calculation of the minimum number of fasteners is carried out according to the following formula for the most unfavourable load case. In any case, a sufficient number of bolts ensuring an effective connection between ring and support frames must be kept, in order to avoid any ring deformation. Where : N = Number of bolts theoretically necessary.
