KUD01897-040WA15-900-000 Slewing bearing

Two-row four-point bearings have a second ball raceway and with the same diameter can take significantly higher loads than single-row four-point bearings. They are in use in applications with high static loads and limited installation space, e.g. rotor blade adjustment in wind turbines.
