  • Load Calculations for Three Roller Type Slew Ring

    2009-10-6 · Slew ring bearings are routinely used to take heavy loads under a combination of eccentric axial load and radial load for off-highway vehicles applications such as excavators and cranes. The type and size of the bearing are determined based on a safety factor and rolling life calculated using a comp

    2011-9-13 · The calculation method of the equivalent loads for the slewing bearings was introduced in SAE 2010-01- 1892. 1) However, in this previous paper the calculation method could not be applied when an axial load does not exist. The specific case with no axial load but with a moment due to an eccentric radial load is introduced in this paper.
