it consists of a thick-walled outer ring with spherical outside surface profile, a solid roller stud with a thread for fixing, rolling ribs and a full complement of rolling elements as well as lip seals on both sides
it has a particularly high load capacity by the maximum number of rolling elements and supports either high radial or high axial loads from slighter misalignments and skewed running
it has a temperature resistance ranging from -30°C up to +100°C, limited by the seal
the outer ring is guided by the central rib and the rolling elements
