A flanged bearing cartridge is provided comprising a sintered powdered steel flange housing formed of a steel composition consisting essentially by weight of up to about 6% Ni, up to about 3% Cu, up to about 2% Mn and/or Si, about 0.2 to 1.2% C and the balance at least about 90% iron. The sintered flange has a density ranging from about 80 to 92% of actual (theoretical) density of the composition and has a circular bore for receiving a bearing, the bore having a continuous inner wall of predetermined axial thickness located centrally of the housing and passing axially through the plane of the housing, the inner wall being configurated with a spherical groove and having inserted therein an annular anti-friction bearing comprising inner and outer rings with a complement of bearing elements held therebetween. |
