A robotic body includes a first section and a second section. The first section includes a first wheel, and the second section includes a second wheel. A coupling assembly couples the first section and the second section. The coupled first section and second section are movable together via operation of the wheels. The coupling assembly includes a housing defining an interior chamber, a spindle disposed in the interior chamber of the housing, and a bearing device disposed in the interior chamber and between the housing and the spindle. The bearing device allows the spindle to rotate inside the interior chamber and relative to the housing. The first section is coupled to the housing and the second section is coupled to the spindle. The first section rotates relative to the second section according to a rotation between the spindle and the housing.

A bearing and seal arrangement for joints in heavy duty vehicles includes two spherical bearing each having an outer ring surrounding an inner member with lubricious liner disposed therebetween One of the spherical bearings has a seal receiving area having an axially extending width that is greater than that of the other spherical bearing The spherical bearings are aligned coaxially with one another One seal receiving areas has a flexible double lipped annular seal and a scraper seal positioned therein The scraper seal is positioned radially outward from the flexible double lipped annular seal The other seal receiving area has a boot seal positioned therein

A work vehicle comprises a front frame, a rear frame, an oscillation frame, a slew bearing, and a rolling-element bearing. The slew bearing and the rolling-element bearing allow oscillation between the oscillation frame and the rear frame about a fore-aft axis.
